I was recently giving my tub a quick cleaning at the waterline with a Mr. Clean Magic Eraser, which I have found in the past works for this very nicely ( and for many other things too). However I had inadvertently used a "Bathroom" variety which must have some kind of detergent within it. I noticed excessive foaming, almost right away afterward. Is there anyhting that can be done to get rid of the soapy mess? Will it clear with time, or is a drain and fill in my near future?
