Don't oil the old 13g chips. Those are most likely plastic slugged chips and will NOT absorb the oil. The Paulsons are
RHC, so they'll do fine in both the U/S and with oiling after. The vinegar will only be necessary if there's an odor on them (like smoke). Pre-soaking ... my man
@Ben8257 must have gotten to you! He's got an amazing regiment for cleaning, all without an U/S. I don't know how Ben doesn't go mad from hand cleaning. But I don't think you'd need to pre-soak. It won't hurt, but I don't know if it's necessary.
90s is the max I'd ever leave my RHCs in the U/S. It'll get 95% to 100% of crap off of them. Some of the H&C's around the border might need a toothpick or toothbrush to really get em clean.
I rinse my chips in continually refreshed clean water right after they come out of the U/S; I don't want the detergent staying on them too long.
