Ultrasonic Chip Cleaning (28 Viewers)

Anybody have good soaking methods ? My hands and wrists are killing me cleaning these chips lol again I soak in 80% arm n hammer oxy laundry detergent 20% water for like 20-30 mins then hand scrub with a dental brush semi hard bristles
Have you tried a kitchen scrubber brush? Unless you're working with hot stamps, there's no reason to use a small toothbrush. Probably better ergonomics than a toothbrush, too.
Also, TSP substitute is great to use for soaking - most of the grime practically falls off on its own, after that.

What type of TSP substitute ?
 
What type of TSP substitute ?
It's literally called TSP substitute. It seems like it's what everybody used around here, before ultrasonics became so popular.
TSP (tri sodium phosphate) is what we always used to use to clean walls before painting. I think it's basically a degreaser. But at some point, they decided it was bad for the environment, and they outlawed it. Maybe it's a state to state thing; I don't know. But if you walk into the hardware store and ask for TSP, they'll sell you TSP substitute.
I would imagine TSP would work just as well, if not better, if it's available in your state. But I've never tried it on chips, so I can't tell you to use it.

Thanks for explaining that so well. I've always wondered about the phrase TSP substitute.

When soaking chips in this stuff how long should u leave the tsp sub sit in the water before adding the chips ?
 
First time doing the US was awesome. Thanks for all the great instructions and tips. My only adds are that I used two more zip ties as a hinge on my lid, added a yellow gear tie so I could secure the lid on the other side and zip tied down the spinning ties because it was driving me crazy that the chips were getting stuck in there and then splashing everywhere.

Tap water, Course Salt and Dish Soap at 42 degrees Celsius does a great number on most dirt and grime though sometimes benefits from a small wipe with minimal "shake" time and chemical exposure so no bleaching. ~20-30 second followed by a wipe or hot water spray with good pressure followed by another 20-30 seconds can give some great results. I have only ever put chips directly into the tray with none of these fancy salad spinner gadgets.

I layered the pictures side by side in "MSpaint" which gave me this cool side by side shot of pre/post Majestic Star NCV 1k chips. I wouldn't mess around with TSP chemicals or anything. The rest of the ingredients are safe to handle (by anyone), non bleaching and readily available in the cupboard.

I may have to try this recipe on old Burt/ASM chips (i.e. horseshu mold Binions Horseshoe chips).

Got any rough proportions?
I have a 6L tank, I did not measure anything but my guess was a healthy 3-4 tablespoons (aim for greater than 1% Solution) of course salt and a healthy portion of dish soap (ie 2-3 dish sinks worth). The salt creates a hypertonic solution which will draw "stuff" out of your chips by osmotic pressure in addition to the soap. Also on the microscopic the salt ion's act like a very mild abrasive which helps clean. For those 1 k chips 20 seconds with ~10-20chips/cycle then I tooth brushed, rinsed and cycled again for ~20 second more followed by a rinse again. For less dirty chips the tooth brush is not required but obviously those orange 1K's qualified as gross before cleaning.
another pre-shot (those 500's must have been the best of the bunch, the rest were just as gross as the 1k's)

I also used the same technique to clean some THC leaded hot-stamps and it worked out well so it is a Hot-Stamp safe method of cleaning.

Thanks for the write up!

Do you soak them prior putting into the ultra sonic?

maybe for a minute or so until everything is set up. I fill the tank with warm water but try to stay at ~42 celcius....anything more is too hot and when under 38ish degrees it does not clean as well for some reason. What I do for a good clean is put them in flat with the faces unobstructed ~10-20 per tray, then I stack em in the water, wipe one at time over the water and rinse em all in the tray with my kitchen sink spray before cycling again the same way. Brushing the chips is not to "remove" all of the dirt but simply loosen what the ultrasonic has raised so far then by using the ultrasonic for another cycle to shake off what was previously loosened. For less dirty chips (the 25/100/500/1000 Majestic Star chips above were all dirty). These HSI chips went in batches of ~200 for 30 seconds followed by spraying with the kitchen tap vigorously and cycling again for ~30 seconds. They were clean-ish but still a bit of grime now they are at least clean where my home game dirt can be what fouls these chips eventually.

Thanks for sharing your process!

Translation for Americans:
42 C = 108 F
38 C = 100 F
 
Bought some chips with a few mixed in that were faded-probably from someone incorrectly cleaning them at some point . Oil brought them back a bit, but was wondering if the fade permeates the whole chip or if scrubbing off as little as possible of the edge surface layer with a magic eraser would uncover unfaded material? Anyone tried this? Results? Thanks

It's fairly common to have just surface reaction, so I would give the magic eraser a go. White chips improve the best.
 
Apologies if it's been asked and answered elsewhere already - does anyone know of an alternative to TSP/TSP substitute? It doesn't seem to be available here in Switzerland and so I'm looking for a suitable substitute. Thanks!

Is This Topic for You?:
––––––––––––––––––––––––––––––––––––––––

Before we start, I consider my own time valuable, and out of respect for others, I don't want to waste YOUR time. To see if this topic is for you, mark the following statements below TRUE or FALSE:

1) I like having a little dirt and gunk on my poker chips. I think it lends some casino class.

2) I don't insist that my poker chips are 100% clean. 80-90% is good enough.

3) I enjoy scrubbing chips with a toothbrush and/or Magic Eraser and/or dental pick.

4) I don't really put any value on my time, and I don't want to spend any money. Besides, I scrub chips while watching TV, and I can focus on two things at once and still do a great job cleaning my chips.

5) I don't notice the permanent fading of my chips that occurs with some colors when I give them 15 minute or longer hot soaks in Oxi Clean, or if I notice the fading, I really don't care.

6) I have filthy Burt Co./ASM/CPC chips to clean.

7) I already own a high-end Chip Brite® ultrasonic cleaner!
http://www.tcsjohnhuxley.com/en/live-gaming/utilities/chip-washer.html


If you marked ANY of the statements above TRUE, then I recommend that you stop reading now, as THIS TOPIC IS NOT FOR YOU. To borrow another member's infamous tag line, it's a "No thanks." :D



Summary:
––––––––––––––––––––––––––––––––––––––––

This updated topic describes a process I've used to effectively clean dirty used Paulson chips (RHC, SCV, LCV) with an ultrasonic cleaner and sodium metasilicate with a minimum of effort. I've also used this process to clean ceramic Chipcos (Hard Rocks) and Bud Jones roulettes (Aztar). To be clear, just as with traditional manual baths followed by scrubbing/wiping/brushing/etc., this process only cleans the dirt and filth from the chips, i.e. it does not remove chip marks that are a result of harsh contact with other chips, like rack checks. Photos can be found at the bottom of this post.

Please be sure to do TESTING on a small number of chips prior to using ANY cleaning process on large quantities of expensive chips!


Bottom Line Results:
––––––––––––––––––––––––––––––––––––––––

This process results in completely clean chips for me, with absolutely NO brushing, scrubbing, or wiping whatsoever (i.e. no toothbrushes, Magic Erasers, etc.). Using this process, I am able to consistently clean 1,000 Paulson RHC chips (such as dirty Aztar E, Par-A-Dice, and Garden City casino chips) in an hour. This timeframe includes a 45 second ultrasonic bath for 40 chips at a time, plus the time necessary to rinse the chips in clean water, soak for 1 minute in white vinegar (5% acidity - to eliminate cigarette smoke odor if your chips have it - done while ultrasonic cleaning the next batch), pat them dry with a towel, and lay them out flat on a table for overnight drying.

Filthy Paulson SCV/LCV chips you ask? I can get 1,000 nasty Empress chips clean in 1-1/2 hours (as long as someone else hasn't previously tried to clean them, which makes the job a lot harder).

Hot-stamps? I've cleaned Casino Miami 300x gold hot-stamp fracs and 20x silver hot-stamp $10 chips with no discoloration or other problems using sodium metasilicate.

The speed is a combination of the fast ultrasonic cleaning, and setting up a good workspace and process that doesn't involve a lot of individual chip handling, walking back and forth, etc. These timeframes do not include equipment setup or cleanup, nor do they include time necessary to explain to your significant other exactly why you need to co-opt her kitchen.


Equipment and Materials:
––––––––––––––––––––––––––––––––––––––––

1. Hornady "Lock 'n' Load" Magnum Sonic Cleaner - dual transducer ultrasonic cleaner with 140 W of power (currently about $200 on Amazon).
http://www.amazon.com/Hornady-Stainless-Steel-Sonic-Cleaner/dp/B004EXWERQ

Do NOT skimp here. If you get a smaller, low power, single transducer unit marketed as a "jewelry cleaner", you WILL be disappointed.

The ultrasonic cleaner is also great for jewelry, glasses, fuel injectors, carburetor parts, filthy used chip racks from casinos, and even the stainless beverage holders in your poker table that get nasty after a few games!


2. Lundmark "TSP" (sodium metasilicate) Hard Surface Cleaner
http://www.amazon.com/Lundmark-TSP-Hard-Surface-Cleaner/dp/B001001VRA/

I hate the false advertising by Lundmark and others that boldly put "TSP" on the labels of their products that are NOT trisodium phosphate, but I love the way that sodium metasilicate cleans chips.

3. A plastic "chip barrel cage" (my term) taken from something called a "Salad Spinner" (about $8 for the one I got). I found this in a local Kroger grocery store. Below is a link to a salad spinner on Amazon that is identical to mine, though it's currently about twice the price that I paid in the grocery store:
http://www.amazon.com/gp/product/B005JYZSTK

IMPORTANT NOTE: In order to get good "turnover" of the chips while rotating the cage, I added four plastic ties to the sides of the cage. This easy modification significantly reduced the amount of time it takes to clean the chips! See the photos at the end of the topic.

If you can't get the same thing, substitutions could be made here, as you just need something to contain the chips while you rotate them during the ultrasonic bath. However, I strongly recommend plastic instead of metal here, in order to prevent tearing up the stainless tank in the ultrasonic cleaner. I also recommend finding something as large as possible that still fits in the ultrasonic tank.

4. Distilled Water (around 70-80 cents/gallon) - for better cleaning, and to help ensure that others who try this process will get similar results. Depending upon the hardness of the water in your location, use of distilled water can make a significant difference!

5. A large clean bowl to use for rinsing the chips in clean water after the ultrasonic bath. I used the large plastic container that came as part of the "Salad Spinner".

6. Lots of clean towels to pat dry the chips, and to wipe up any minor splashes that occur during rotating the chip barrel cage during the ultrasonic bath. I recommend "bar mop" towels. They are great for drying chips, and even better for wiping excess mineral oil from chips. They're also very cheap if you buy a pack of them at Sams or a similar warehouse club, and they'll keep you from getting in trouble with the missus for using her nice towels for wiping chips. Here's an example at Sams:
http://www.samsclub.com/sams/bakers-chefs-bar-mops-16-x-19-24-ct/prod3530205.ip

7. Measuring cup for the distilled water.

8. Measuring spoon (tablespoon) for the sodium metasilicate powder.


Process:
––––––––––––––––––––––––––––––––––––––––
IMPORTANT - INSPECT RESULTS ON THE FIRST BATCH OF YOUR OWN CHIPS CAREFULLY PRIOR TO CONTINUING TO CLEAN THE REST OF YOUR COLLECTION!
This process did not damage any of my Paulson chips (including thousands of Casino Aztar Evansville, Par-A-Dice, Garden City, Casablanca, Empress, Casino Miami, and others). To the contrary, it eliminated nearly all the fading problems I was experiencing with longer/hotter Oxi baths. It also bears noting that this process, which includes tumbling the chips in a cage in the ultrasonic bath, did NOT impart any visible damage (chipping/nicks) in even the most fragile of chips that I cleaned - some near-mint white RHC Terrible's $1s that still had razor sharp edges, but had become grey from cheesy dirty hands in someone's home games! However, your own chips, equipment, and process conditions COULD yield different results, so be careful! I'm not responsible for any damage that might occur using this process, any more than any of the other helpful people at PCF & CT are responsible for minor damage (fading) I inflicted upon small numbers of my own chips when I followed some of the traditional processes noted in the forums! :D

Here we go...

0. Prepare your workspace, and be safe! This goes a long way toward speeding the overall job. I recommend locating the ultrasonic unit very close to the kitchen sink, with some space close by large enough to place a medium towel that will be used for the initial drying of 40 chips at a time. Put your large bowl for rinsing in the sink and fill it with clean warm water. Get your towels ready.

KITCHEN AND PERSONAL SAFETY:
• Cover any kitchen countertops, cabinet faces, backsplashes, etc. that could be splashed with the sodium metasilicate solution. Don't forget to cover the floor nearby, too! Your personal safety is at risk if the missus finds that you've ruined her kitchen.
• Wear eye protection.
• Wear gloves. The thin latex gloves you can get at the drug store work great.

1. Heat 2 cups of distilled water in a clean measuring cup in a microwave for about 3 minutes.

2. Pour the heated water into the tank of the ultrasonic cleaner.

3. Dissolve 2 tablespoons of Lundmark "TSP" sodium metasilicate in the hot water.

4. Add 6 more cups of distilled water to the ultrasonic cleaner, for a total of 8 cups. I found that this gave me something close to the 110 F temperature that I wanted to use.

5. Plug in the ultrasonic cleaner, and turn on the built in heater if the temperature isn't yet up to 110 F. Turning on the ultrasonic transducers will heat the water even faster if necessary.

6. Put 40 chips in the chip barrel cage.

7. Set the ultrasonic cleaner timer. As a guideline, I recommend the following times:
• Lightly soiled Chipcos - 30 seconds
• Lightly soiled Paulsons of any mold - 30 to 45 seconds
• Heavily gunked up Paulson RHC chips - 45 to 60 seconds
• Heavily gunked up Bud Jones roulettes - 60 seconds
• Heavily gunked up Paulson SCV/LCV - 1-1/2 to 2-1/2 minutes

If you have some PREVIOUSLY CLEANED Paulson SCV/LCV chips that still have gunk in the rings and Hat & Cane mold, you may find that the gunk has been hardened to the point where even 2-1/2 minutes in the ultrasonic bath won't remove it. I'm not sure whether the previous cleaning process, detergent, and/or heat causes this, but I've experienced it. In any case, if you have chips like these, I recommend you give 2-1/2 minutes a shot, and if that doesn't work, give up and resort to getting the hardened gunk out with a dental pick or the back side of the point of an X-Acto knife. If you elect to trying longer baths in the ultrasonic unit, please be VERY careful to watch for fading.

8. Place the chip barrel cage with chips in the ultrasonic tank, and turn on the ultrasonic cleaner.

9. Rotate the chip barrel cage by hand for the entire ultrasonic cleaning time. I've found that 1/2 rotation per second works best. You'll note that the ultrasonic transducers add a lot of energy to the bath that's absorbed by the chips and radiated as heat, i.e. the temperature of the water will rise during the bath. I try to keep the temperature around an average of 110-115 F.

SAFETY CAUTION: BE CAREFUL TO KEEP YOUR FINGERS OUT OF THE ULTRASONIC BATH WHILE THE UNIT IS RUNNING. IF YOU DON'T, IT WILL *NOT* FEEL GOOD!

Also note that I've experimented with a lot of different rotation speeds, and alternating between rotating/waiting, etc., but the constant 1/2 rotation per second has worked best so far.

10. When the ultrasonic cleaning cycle has completed, slowly remove the chip barrel cage from the tank, give it a gentle shake, and allow the excess water to drain back into the ultrasonic tank.

11. Dump the chips into the bowl of warm clean water to rinse. Agitate the chips by hand a bit to ensure they're well rinsed.

12a. If your chips have cigarette odor, take them from the rinsing bowl, shake the excess water, and put them straight into a container of 5% distilled white vinegar (I use a cheap plastic tupperware-like container for this). Then begin ultrasonic cleaning your next batch of chips while these cleaned chips soak in vinegar to remove the odor. When your next batch of chips is clean and in the rinsing bowl, remove the chips from the vinegar bath, shake the excess vinegar, and place them on a towel to pat dry as in step 12b (you don't need to rinse them in water again).

12b. If your chips don't have cigarette odor, remove them from the rinsing bowl and lay them flat on a towel, and pat the tops dry with another towel. Remove and place the chips flat on a large towel on a table for overnight drying prior to oiling.

After patting dry, I move the chips to the "overnight drying table" (my poker table) by picking up the four corners of the bar mop towel on which they were pat dried. Over the long haul, this saves a lot of time by minimizing the handling individual chips.

13. Loop back to step 6 and repeat as necessary until you're done. Note that I use the same bath of sodium metasilicate water for 1,000 chips, and though filthy at the end, the original bath water is still effective in cleaning the last batch of chips. However, I often find that after cleaning about 1,000 chips, the sodium metasilicate bath becomes very foamy (possibly from detergents used to clean the chips at the casino) to the point of spilling over out of the ultrasonic unit. So, I usually change out the bath water about every 1,000 chips when I have more than that number to clean.

Thanks for sharing, i have 3 sets to clean but havent thought of investing in an ultrasonic
 
Anyone know if the L mold chips are safe in the US? Think they were made or sold by C.W. Rice. Nice and leaded too. Thanks

Wow, I totally misunderstood this question. My initial reaction was "Well, they're fine in Canada, so I guess so...?" :oops: :wtf:
Sounds like you’re still recovering from Vegas. The US will do that to you o_O

I tried it on some of the older chips I didn’t want to use chemicals on and this recipe worked pretty good. I like the fact that it doesn’t have any harmful chemicals and I can do it inside without worrying about damaging the countertops.

I love how TSP is a "chemical" but dish soap and salt are somehow not.

Everything is a chemical.
I think I classified it as a “harmful chemical”. I would gargle with salt water, but not with TSP water. Adjectives matter!
