Cob Web Cleanup does not contain any solvents or products that will dull paint. What it will do in some cases is clean dirt off of the surface. If it is overapplied and allowed to drip or run, occasionally on dark or white surfaces, it appears that the colors have changed. This is only the area where it was applied is actually cleaner than the surrounding areas, so it appears as a "run" or "drip". If the area is power washed first, and even hand scrubbed with soap and a brush and rinsed off, then Cob Web Cleanup applied, the chance of runs or drips are greatly reduced. The best advice is to not over apply it and don't let it run.
