Ultrasonic Chip Cleaning (21 Viewers)

[Gear]

Would an ultrasonic be able to clean these marks? I already gave 'em a good scrubbing w/ a toothbrush+Dawn, i'm satisfied that the hooker juice was cleaned off, but these rack-check marks are some of the most vicious that I've ever seen. Any tips, or should I just invest in a ultrasonic cleaner?

Ultrasonic won't touch that. You need to either scrape them off carefully with the back of an X-Acto or utility knife, or use a magic eraser.

BTW I hope everyone understands that magic erasers work because they are abrasive and actually remove material from whatever they're scrubbing ... in other words, they take rack-check marks off because they are basically very fine-grit sandpaper. GO EASY with the pressure or you will take off too much of the chip.

I only use abrasive scrubbers on the chip edge. I'm too scared to wreck the mold and texture off the face of the chip.

What are you soaking it in before the US bath?

 

[Gear]

16 minutes???

16 minutes???

Yeah, a bit long. The Paulsons will survive, though. He's not agitating with a salad spinner, so will need a bit longer. Probably giving it a stir now and then.

 

[guyfleegman]

Pre soak in warm water.
20 minute timer...
2:00 bath with spinner.

 

[guyfleegman]

All done with 900 chipes! Hour and a half.

Not a theory; it's fluid dynamics. I worked in the ultrasonic inspection field for years.

Sound travels easily through water. Air (aka, bubbles) in water reflects sound waves. Bubbles prevents sound waves from reaching a target (if inspecting), identifies a target (like voids in metal), and prevents the waves from effectively reaching target chips and creating cavitation (microscopic bubbles that essentially explode, creating a shock wave that is the cleaning effect on chip surfaces). Also why leaving chips in the ultrasonic for very long periods of time will eventually destroy them.

Cavitation is some pretty powerful stuff -- it can destroy ship propellers and internal pump impellers, among other things. Additives are often part of the solution to minimize damage caused by unwanted cavitation.

@horseshoez @TKO this seems to be the thread to read as far as ultrasonic cleaning is concerned

@Steppenwolf this paired with the vid, done deal.

Another 1400+, damn I'm getting tired....

Okay, that's just begging for the Out Of Context thread.
Unfortunately, can't be online on Sunday when the sale goes live.

What, why? Traveling?

ugh why won't they ship to hawaii...... even the TSP i can't have shipped to me

@davin just let me know if you want me to quote shipping. Happy to help. Could ship the TSP tightly inside a ultrasonic even to help with shipping

@CacheCreekCollector Have you tried a magic eraser? I have seen others comment that it removes "check marks".

I tried a Magic Eraser on some Starbursts recently... As @Gear and others have noted, while it does clean up a lot of stuff other methods don’t, it is kind of like sandpapering your chips. Have to use very lightly if at all.

It is, in fact, exactly like sandpapering your chips!

What is the current recommended Ultrasonic option?

You sell these?

 

[Chile85]

@davin no, I would be willing to help ya out and get it shipped from US mainland if you would like. Just trying to help a chipping brother out.

That’s awesome I’ll keep u posted

Many of us are using the 6L capacity Vevor unit with reliable results.

 

[DaSinical1]

Just got my setup in and wanted to do a test run. Cleaned 250 chips in less than 20 mins and minimal effort. I'm a believer.

Thanks OP for showing me the light.

 

[davin]

Can’t wait to try mine out. Just got in today
My hands still throb from last time I cleaned chips manually

 

[davin]

I’ve heard on red chips to not go to high on temp, what do you folks recommend on paulson Red chips.... I’ve hand scrubbed with warm water and dawn and had red bleed in water already so don’t wana ruin in ultrasonic.... I want to prepare my self prior

 

[allforcharity]

Use around 37C. I do most chips around 43C.

There goes another 1000

Ancient ASMs in the foreground on DISQ mold. I only put them in for 30 seconds to minimize possibility of surface destruction. Worked alright, with some trace colour loss.

What's going on with that broken chip with tape on it? Testing for colorfastness?

 

[davin]

Anyone else hear like a sizzle noise when you first put chips in ?
