Hello everyone,

I have few plastic cards(KEM and COPAG) and use them about 10 hours/week.
And about every 2 weeks, I feel that cards become little stickier when I shuffle them.

I usually wash them with cold water and everything is fine.
But just out of curiosity, is it okay to use ultrasonic to clean plastic cards?
 
Try with some older setups that you no longer use. My initial thought is no but it could work as long as you use cold water.
 
I don't think this would be efficient. Hard to separate the cards in a small dimension bath, maybe? I think if would be reasonably fast just to wipe it down with a cloth.
