Yesterday I drove my car through one of those touch free car washes cuz I was lazy. Well today I opened up my trunk and saw grey spots splattered all over my box. Somehow the water from the car wash got in my trunk. I look at my sub and the cone is discolored from whatever was used to wash my car. The middle of the cone where the water was sitting is very faded and when the sub hit, the water splattered all over the cone. Does anyone know a way that I could take all the color out of the cone so the whole cone will be the same color? The cone looks horrible right now. Any ideas would be great. Thanks, Matt
