Hey Guys, I've been collecting transformers for about two years now. Love this stuff. Anyways, my transformers on my shelf are getting dusty? How do you guys clean it? I usually just use a dust can to spray it but I'm pretty sure you guys have better ways of cleaning it? Also, I notice that a lot of you guys recommend nail polish to make loose joints sturdier. What item or tool do you guys use and what technique? Thanks a lot. Really enjoying my TF collecting experience so far.
