Quoted from Damien:
Should naphtha be used each time you give your game a clean up, or is it better to use Novus 1? From what I've read earlier, you mentioned Novus 1 can be slightly abrasive.
Just wondering if it is safe/recommended to use naphtha on 90's-current games. I usually do a clean up every 2-3 months.
For light regular non-waxing cleanings whenever I take of the glass for something.
I clean off the ball tracks on standup targets with RC-88 and a q-tip (dont use it on anything plastic please).
I dampen a yellow felt polishing rag with mist n shine and rub down wherever I can reach to remove coil stop dust (works good on all plastics too). You can poke and pull a yellow felt polisher rag thru, under and around a lot of areas with a wooden spoon handle or a rounded piece of 3/8" dowel. I cut the rags up as necessary to get then into places that are tight.
If I have time to clean ball tracks I use a tiny bit of novus 2 on a small microfiber rag and rub them off.
Note: novus 2 will remove the wax in areas you use it on, as its abrasive.
Then I have to apply a super thin, almost non existent layer of carnauba over the ball track area, let it dry for a few mins and buff it off.
This differs from a big cleaning in that I spend a lot more time on a thorough cleaning inspecting nuts, bolts and screws and then wax all of the playfield I can reach with a thin coat of carnauba.
On other days I inspect the underside of the playfield and vacuum off black coil dust along with the inspection of all of the screws, bolts and nuts. I clean inside the inserts with a q-tip and rubbing alcohol.
I also tug on and inspect wires for looseness and check each solenoid plunger for smooth operation and repair or clean as needed.
I clean plungers and coils sleeves with naptha to degrease them. Especially on the flippers.
I also vacuum out the lower cabinet and wipe down the harnesses with a rag and sparkle glass cleaner.
I also use sparkle glass cleaner on plastics of they look grimy.
I only use naptha on the playfield to remove all the wax, when I change out all the rubbers.
Since you have to remove all of the assemblies, its a good time to really clean off the playfield. I do it in sections as I go.
For me its about 3000 to 5000 plays.
Notice that I havent mentioned novus 1. I rarely use it. Mist n Shine is sufficient if you have it.
