Woolite Heavy Traffic Foam Carpet Cleaner performed no differently than a normal carpet cleaner would. It works great for little spills on the carpet and stuff like that. It did nothing for the area by my door that gets a lot of traffic and has discoloration due to said traffic. I have an area on my carpet by my door that you can tell get's a lot of traffic in and out of the house. It is a little bit darker in that area due to the grime and whatnot that's been brought it from outside. I saw the Woolite Heavy Traffic Foam Carpet Cleaner and thought that was the exact thing I had been needing! I followed the instructions. It had a little bit of a chemical scent to it but it was not over powering. The foam that came out of the can wasn't all that foamy. I let the product work it's magic [or lack of]. I vacuumed it up and noticed no difference in the area whatsoever. I've continued to use the product on random areas where food got dropped or my cat had an accident and it works fine for those areas. It just doesn't do what it claims for high traffic areas. I recommend it as just a normal carpet cleaner. Not one for high traffic areas.
