Quoted from Jaywoods06:Share your biggest pinball mistakes. Laugh at others miseries and let them laugh at yours.
So I was going to clean these and I use an ultrasonic cleaner on some of my pinball parts so I decided to try it on these....... well it didn't go as planned...... take a look at the before and after photos
