My carpets are about 4 years old and a light colour, wanted to freshen up the traffic areas, just a bit grubby from foot traffic, and a few marks, made no difference at all! Didint lighten any of the marks which are of various substancesTotal waste of money and time, no better than vacuuming, should have just gone and got a rug doctor in the first place!
