Quoted from investingdad:So if somebody had a NIB pin for home use only...What is the recommendation for gentle cleaning (use what and how often) and should wax be put on the playfield while it's still pristine?
Lots of people use Novus 1 for gentle cleaning, but that product is actually designed for plastic. Not saying that it won't work, but I prefer to use something that was specifically formulated for the job (cleaning a clear coated surface).
For regular cleaning without worry about the cleaner removing your wax, I recommend using Optimum Opti-clean. You can't over use it, and it can actually help maintain your wax with it's polymers. I use it every time I have the glass off (for whatever reason).
You can buy it concentrated. Mix with distilled water. It will clean plastics as well.

And yes, you can apply wax to a brand new pin.
