I actually got it from Vapexhale, but I think it was a limited run because it's been a while since I've seen it on the website. For an ultrasonic cleaner you can do something like this. I soak the nails and baskets in the ultrasonic cleaner filled with the highest concentration isopropal alcohol I can find. Usually soak them overnight or for a day, but it doesn't have to be that long, and I'll just turn on the ultrasonic cleaner here and there during that time.

​

Then when I'm ready I'll take them out, brush them off good to remove the remaining stains, soak in clean iso for a bit, dry off, and then finally burn them off in the vape with it set to the highest temp (in case it needs to be said, always be careful with iso around heat, otherwise you might lose some hair or go boom).
