Quoted from scubadiver6:I'm new to this hobby and have some basic cleaning questions for you:
1 - Can you expand on your cleaning methods a bit more?
2 - Are you using alcohol on a cotton rag (with elbow grease), then going over it with the Magic Eraser? (or vice versa)
3 - What kind of alcohol do you use?
4 - In your experience, is the combination of alcohol and a Magic Eraser safe enough just for a thorough cleaning (i.e. when you have no intention of stripping the playfield down, sanding and re-clearcoating)?
In other words: If you were not completely restoring a playfield - yet the playfield was pretty dirty - would your cleaning techniques change?
I have a Taxi and am looking for the best/safest/most effective way to clean a System 11 playfield....
This thread is amazing! I've learned quite a bit!

Here's my best understanding...
terryb has an awesome site with tons of great information: I've learned a lot there about soldering and cleaning playfields:

In short, have an approach to cleaning a playfield like you would with wood flooring...
Would you wet-mop a dusty/dirty floor first, or vacuum it first? Why? The idea is get as much stuff off of there dry as you can, before you go "wet" -- once you go wet you are creating an abrasive mud that will then pack material back into grooves.
dry vacuum / dry rag / soft bristle brush... get all the dust off possible, before going to microfiber towels and 91% isopropyl and creating "mud" to clean/scour with.
When you've cleaned to your best ability with rags/91% -- then move to a magic eraser which has an abrasive quality. You want to do this once "as much particle" is removed as possible... that way you aren't magic-erasering with a tiny film of mud... For me the magic eraser step is about two things:
1. removing a yellowing of whiter/lighter areas
2. removing ball swirl marks
What this means is I don't necessarily magic eraser the entire playfield. Every bit of magic-eraser cleaning we do on a micro-level is abrasive and hard on the surface. If we just do it once carefully every 30 years, hopefully we'll be ok...
