A few months ago my DS (and I - well I can't heap all the blame on a 2yo) spilled a large bottle of bubble mixture on the dark beige carpet.
Thought I had cleaned it up OK using vanish at the time but it soon turned into a dark mess that got blacker and blacker. So I spent ages cleaning it up again with vanish again but lo and behold it turned into a black mess over time.
I think that the bubble solution has made the carpet area sticky and so any particles around get trapped and so a nasty looking black mark builds up.
I know life is too short to worry about a perfect carpet but it looks truly dreadful and would love to get rid of it once and for all.
Anyone sucessfully cleaned this type of stain??
