If you clean Them they wont harm anything. That is what is going wrong with our Country today, Is that everybody goes with the crowd.( Politically correct) pier pressure, to the point they let the crowd dictate what they do. People do what ever you want to. Don't ***** at others for doing what they want to. It would be a boring place if everything looked just alike. Hey it might look like the little blue suits that all the Chinese all like to wear. LOL
