In the past I've tried a toilet bowl cleaner that had a strong acid to it.What have you tried so far?
I would think most any rust remover would work, and be safe to the VCT
Sure. I use it on all sorts of tile, porcelain, ceramic and vinyl all the time, I mean why not? Fabric, why would it harm anything else other than natural calcium based stone?In the past I've tried a toilet bowl cleaner that had a strong acid to it.
I never thought about trying a carpet cleaning rust remover.
Have you tried it?
