I have a 2006 Bounder with stains in the ceiling. It seems to be a carpet/fabric material.

Any suggestions to remove it or color over it somehow?

Thanks 

Water sometimes will leave an unsavory stain on our RV roofs. This can be a hard stain to remove without damaging the surface around it. An inexpensive and simple solution to removing the ceiling water stain is simple hydrogen peroxide. Dab a clean sponge and 100% hydrogen peroxide on the stain. Then absorb the stain with a clean paper towel.  Repeat until stain has disappeared. Always make sure to color test a hidden area before using the hydrogen peroxide and cover your carpeting below with a piece of plastic.
