We renovated our home recently. When I was going to place my old trophies in the showcase, I noticed most of the trophies are faded and some of them have some damages. From a blog (http://www.houlthellewell.com/blog/trophy-color-fading/5-reasons-your-trophy-colour-is-fading/) I understood that repairing these trophies ourselves is not safe. I want to know is there any ways to remove the stains on trophies and to clean its wood base.
