Things You'll Need
Instructions
Cleaning
Remove the playfield glass from the machine and clean both sides using a rag and some glass cleaner.
Clean the playfield by wiping it down with microfiber cloths dampened with pinball playfield cleaning solution, which can be purchased from a hobby shop. Wax the playfield with a wax/polish when finished.
Clean the bumpers and other components of the playfield, like the decorations, with a cotton swab dipped in 90% isopropyl alcohol. This solution dries almost instantly so it won't damage any electrical components.
Maintenance
Replace the rubber o-rings around select components. These rings tend to stretch and crack over time.
Replace all the light bulbs that are burning out or dimming. You'll often see signs when a light bulb is ready to die, like dimming or flickering.
Test the flippers and apply a small amount of WD-40 to loosen them up if they need to be tightened.
Replace the pinballs about once a month, depending on how frequently you use the machine. Worn pinballs can chip and damage components.
