Cleaning pistons

View attachment 1715480542 I bought a $60.00 ultrasonic cleaner on ebay... very good results on valve train parts. I use Purple Power at a 50/50 mix. Turn up the heat and 30 minutes.

try the parts in a ziplock bag with your liquid in the bag. that way it doesnt screw up the tank water and you can dump the dirty stuff without changing the whole tank. thats what i do and then you use way less chemicals and they can be stronger or weaker depending on what your doing.
