I bought a Giga Powermaster figure on eBay. It was in good shape, just a little chrome wear which is to be expected. I decided to give the figure a once-over as I do all my purchases - a light cleaning with a household cleaner. In this case, I used Windex v/ Vinegar. I applied it and started cleaning. No issues really. I looked at the q-tip I was using, and didn't notice any paint build up, primarily because I avoid the painted areas anyways. I went ahead and cleaned the chrome since I have done that in the past with no problems whatsoever. Not this time though. I finished everything and noticed that his back chrome had change from gold chrome to silver chrome! All the chrome was there, but he was now silver. I wasn't aware chrome could react in that fashion. Was the gold coloring painted on? I didn't notice any gold color on the finished q-tip. I'm not exactly sure how it happened, but perhaps this post can be a warning for people who attempt to clean gold chrome in the future. Anyhow, the chrome had wear to start, so I don't really care that the color is off. I'll go out and find some gold chrome paint and paint it back on.
