As mentioned in my previous post about "clear" varnish that is actually yellowish, we have had a problem with mildew stains gradually forming on a wooden panel in the bathroom where the hand-towel hangs.
I've repainted the panel & am going to repaint the yellowish test area white again & then slap a few coats of clear [1] acrylic varnish over it & put the towel hook back up. What else can I do to prevent stains from gradually forming there?
[1] Really clear --- I've done another test area, smaller this time!
