Quoted from Mocean:What's the safest bet here, just in case some crud is covering up a ding in the paint? It's not novus 1, I assume. I just don't want to plank this thing!
Relax, get some bright worklights over the playfield , and don't overthink it.
Get rid of the old rubber - this will make a big mess, so get it over with.
Vacuum first - see how much crud goes away. Use brush attachment and crevasse attachment.
Wipe with soft dry cloth - is the remaining dirt glued on, or did it wipe away?
Wipe with soft cloth moistened with Naphtha to remove any stuck on dirt (if needed) - are you now down to clean playfield?
Vacuum again - take note of any scratches and ball trails.
Use Novus2 - with a soft cloth (old cotton t-shirt is great), polish out any scratches. Polish out the ball trails in the inlanes. Keep the cloth rotated to clean sections, and keep it moist with the Novus2.
Vacuum again - check your work. Ignore tiny scratches you won't see with the glass on.
Wax - Using the included applicator or a clean very slightly dampened with 1 drop of water cloth, rub the wax into the playfield using small circles. If your applicator is dirty from your car, don't even think of using it! Do the ramps, do the metal ball guides, the wire guides, undecaled target faces - every place the ball touches. Don't use too much wax! If using Blitz, use 1/4 of what you would use of Turtle Wax.
Wait 20 minutes - Drag you finger across, if it cleanly removes the wax film, it's ready. If it's slightly tacky, give it another 10 minutes.
Wipe - wipe off the wax film with soft cloth. If you are using good wax, there won't be any white wax chips or flakes at all. Keep the cloth turned to fresh areas.
Vacuum again - if you used cheaper wax, you may need this final vacuum to pick up the wax dust.
Drop in new balls - for $5, why not?
Play.
