I have a brand new machine. How frequently should I be cleaning and waxing the playfield? (I tried searching the forums for an answer and couldn't find it, so apologies if I missed it.)
Using common sense, I expect I'll just wipe it off when I spot any dust/debris, and when I start seeing loss of shine or obvious indicators of dirt, I'll clean and wax. Is that reasonable, or is more preventative care needed?
