Like I said before, this is a solid 101 for those who aren't sure on maintenance like myself. It contains great tips on how to keep your figures looking nice and new. I haven't seen many of these on dA myself so it's a pretty good find from an evident expert! I think that also it makes me really think about how I've been treating mine for all this time, so I think that this advice will prove great for anyone, especially with tools that are easy to find in everyday day-to-day life. Overall, this is a nice cluster of quick tips for a beginner.
You've got some very good tutorials, I hope more people will learn from them.
About cleaning, something that I've found to be working quite well is the sprayable solution used for cleaning glasses [I mean those you put on your face, not windows and bottles and the like...], lcd monitors or camera lenses [then you wipe it off with a microfibre towel]. It works for stains where soap fails. Also, for dusting off complicated crevices, the air pump used to blow off dust from lenses works pretty well. I don't have a display case and my figures always get so dusty :[ I've seen some really cool ones, with LED lights, completely transparent... Too bad I don't have any more space for something like that.
