No worries. Let's go through it.
First, it is VERY rare that I use Naphtha on a game. I'll use Novus 1 or 2. Depending.
Novus 1 is a thin liquid (Spray the rag, NOT the game). It's nice for a quick cleanup. Have plenty of extra clean cloths as well, and switch them often. You don't want to grind in dirt, you are removing dirt.
Novus 2 is thicker. Not quite a paste, just a very thick liquid. Always shake the container well. Novus 2 is more abrasive. But it isn't really that abrasive. It will get off the thicker dirt layers. Again, on the rag, not the playfield. Always be careful of posts and edges of stuff. If Novus 2 (or wax) gets on a playfield post, you may not see it... until it dries. And there is nothing worse than looking at a clean game with these white toothpaste blotches all over the posts.
Be careful with Novus 2 on very old games and EMs with thin lacquer. You don't need to worry too much on Maiden, but on an old checked playfield, it will remove paint. You will experience it in this hobby eventually.
NO! Never use a wax with a cleaner in it. You are looking for a pure wax with nothing in it but wax. Mothers makes an awesome paste with nothing but wax, you should use that.
The problem with my saying that is others will disagree. They will say they have used wax with cleaners for 10 years without issue, and good for them. I like to know exactly what I'm putting on my game. Cleaners for cleaning, wax for wax.
Because you are new to maintaining pins, I'll say this one up front. Pins don't use lube, except in some small and obvious spots. Never get tempted to put grease in a flipper or something. A similar warning would be to never use WD-40 in a pinball machine, or any spray stuff. At best it turns into gum, and at worse there are still fumes when the game goes pop.
The first time cleaning a game can be a bit intimidating. And that is totally normal. My advice for that is to just do a quick wipedown first. Nothing too deep, just getting used to working on a game.
Balls. Replace them early, replace them often. If you ever notice a scratch or dent in a ball (which can happen as they hit metal), get rid of it. Not tomorrow, not one more game, right in the trash. Most of the time they can be cleaned quickly. And sometimes the polish marks can look like issues, so check with your hands. Any type of ball damage will chew a playfield over time.
Sorry this is so long. Welcome to an awesome hobby that keeps giving back fun. If you have questions, just let me know. If you hear the complete opposite of what I've said, just go with your gut.
