I have a 16x32 vinyl liner pool that was installed last year. Recently I had a company come and stain and seal the concrete around the pool deck. Due to some unexpected wind that day, the overspray fell on the white vinyl coping around the pool and it looks really bad. Is there any way to clean this coping and make it white again? I don't want to damage the coping or the liner.
Thank you,

Before we start looking at ways for you to clean this lets look at ways for that contractor to clean it. This company is responsible for cleaning up any mess they make and they are most likely candidate to know what to use. Do not let them off the hook.
