I have not yet made it to the storage yard to see about the ceiling stain, but I moved some furniture around in the house to vacuum. What I thought was a red ball if lint was some red sticky thing. Well running the beater bar vacuum over it created a wholly mess, not only where it was laying but once the beater bar hit it kind of exploded into the area about the size of a pie pan. Wife NOT happy...So I carried the vacuum out doors, went and got the bottle of Folex that IAMICHABOD suggested. WOW, followed directions, the red stuff disappeared and I also used it to clean the beater bar. This stuff is amazing. I hope it gives the same results on my ceiling. Will post once I get that job taken care of. I bought the big spray bottle at At Bed,Bath and Beyond for $7.00.
