Hey everyone!
I have a beige carpet (not my choice) that didn't seem to look nice no mater what I cleaned it with. I tried the "recommended" shampoo and stain-remover that came with the shampoer, but it didn't work nice. I also tried simple green -better, but not good.
Last weekend I tried Purex detergent. It worked wonderfully! That's all I'm using from here out! I hope this s someone else revive their tired, stained carpet.
