We have a very light cream or off white ceiling headliner. It is very carpet like. We had a fairly large area of staining in the bedroom by the air conditioner duct and a smaller one up front. After fixing the duct and the front air conditioner drain, removing the stain was really becoming a project. No matter what we tried it didn't seem to work. Rummaging around in the garage I found some InVinceable that we had gotten at the fair last year. Yes, it's the same stuff that they advertise on As Seen On TV.
I figured what the heck, we had it, no loss but I wasn't really expecting very much from it. Much to my surprise the stuff worked, even though I messed up and didn't mix it to its highest strength. I sprayed it on, rubbed it in with a paper towel and away went the stain. For a couple of the really bad areas I had to do it twice but it actually worked! I was absolutely amazed! For the stain up front I used the brush provided with one of the failed concoctions that I had purchased to make sure that it got into every nook and cranny of the carpet-like ceiling. It did that one too!
The only drawback with the stuff is that it is only good for about 4 hours before it loses its potency. Since I did not have lots of things to do other places I poured the rest in with a load of laundry.
As I said above, I am extremely surprised by the efficacy of this stuff. If you can get it I recommend that you give it a shot. Remember, you may have to use it twice on some of the worst stains and be sure to make plans to use it all.
