Yellowing of shower surround...
Hi All! I have a 2008 MicroLite 18FBR. The shower surround has gotten very discolored since February. In Feb, it was bright white. We just took it out on Thurs, and noticed it was yellowed. It doesn't wash off, either. I also noticed that the skylight trim has yellowed as well. Any thoughts on what might have caused this?
