Have a shower stall that unfortunately has several corner seams
that were "caulked" with RTV. Of course, by now they have gotten a bit
Have tried all the common bathroom stall type cleaners on it, but no luck.
My guess is that the mold, while probably not on the surface, is not very
deep. But, of course, I'm not too sure of this.
Is there any product that stands a chance of cleaning the RTV, that won't
damage or de-glaze the tiles ?
Really don't want to have to rip out all the RTV if I can avoid it.
