Tilex/Bleach on underside of awning
I've read successfully results of some members using Tilex or Bleach on the underside of the awning to remove mildew stains. Some have posted that they spray it on and roll up the awning for 30 mins or so. The exterior/top side of my awning is a black color while the underside is white. Will rolling it up bleach or discolor the top side of the awning? Any help would be appreciated.
