Hello
After an ultrasonic bath for 15 minutes with a temperature of 38 degrees the brass parts, valve lifter and spring adjuster, are discolored with black spots. My cleaning solution contains a drop of dishwater detergent and a tiny bit of vinegar concentrate. It seems just to be an optical problem however is it possible to prevent this next time and what are possible causes?
Thank You
