Today I looked at a carpet that had a little water damage. I could see on the carpet where some of the legs of furniture were. It had small sort of off red coloration. Is this possible to remove and if so with what product? It almost looked like rust but I am pretty sure it is not. Any feedback would be great! Thanks Sam

If it is rust, I use Vacaway's Rust Assasin product with good results. However, the longer it has been in the carpet, the harder rust is to remove.
The color you see may well be leached-out furniture stain, not rust. If it is, it may well be permanent.
Chlorine bleach might remove it, but will probably also remove carpet color as well.
