For initial cleaning of a dirty playfield I use baby wipes since I will be polishing and waxing it anyway.

But for normal maintenance cleaning, I use Novus1 and microfiber towels. I spray directly on the playfield. Just don't let it sit. I also use a microfiber towel to buff off the wax. Basically, treat it like a brand new car.

Treasure Cove's polishing disk kit is awesome if your playfield is dull.

Novus 2 is a polishing agent. It shouldn't be used regularly as it is a mild abrasive. Mainly used when shopping out the machine.
Novus 1 is a plastics cleaner which is safe for most everything in a pinball machine.
Even if you use Novus2 you should finish with a Novus1 wipe down before waxing.

Yep, Novus 3 is the most coarse with Novus 1 being the finest. Always use the least aggressive that you can get away with.

here is a good video about cleaning a playfield

If it was already waxed you should just give a regular wipe down with Novus 1 or simple green once a month depending how much playing you do. And every so often give a wax in the high traffic areas so you dont wear down to the paint on the playfield. IMO

if using the Treasure Cove treatment - make sure you have a drill that can get up to 2000 + rpms. A chordless batery drill probably isn't going to go that high. I did 2 playfields with a batery drill and wasn't really impressed. However, on my last pin I got a decent drill and was blown away. Check out these before and after pics - and this doesn't even really do it justice. I recommend this stuff.

To answer your original question, gweempose, I use chamois cloths on my playfields during cleanings. I don't think brand name makes a difference. I bought my cloths from the nearby auto parts store (Pep Boys), but I am sure you can find them just about anywhere. As far as cleaning agents go, I use novus 2 for getting the initial dirt/scratch out. If all I need is to do a usual cleaning, I will use novus 1. If the playfield section is easy to get my hand in (so much so, that there won't be any residue left afterwards), I will directly apply a tiny bit on the playfield itself. If its a really tough part to clean, I will apply the novus onto the cloth/Q-tip, and then clean from there.

Other than that, regular old glass cleaner for the playfield glass. To throw all this stuff in, I got a free car wash bucket from Pep Boys, in which I place all my used rags and cleaning agents.
