Christian, All the tea {PB Blaster}in China won't help you if the holes have years of crud along the walls which don't allow the set screws back out and up, therefore causing you to strip the set screw hole. Use a straight pick to try and dig out any dirt in the set screw hole, which is another way of preventing needless damage. I use a .30cal bore brush and cordless drill motor to clean the holes, followed up with compressed air, a pick, and the PB Blaster.
