I received this product from the Ignite program. I used this in my Hoover carpet cleaner and it worked like a charm. We have a new puppy and I forgot what a nightmare potty train is. I put some Hoover stain remover to pretreat and then use Hoover Paws and Claws cleaning solution in the carpet cleaner to finish the job. It got liquid stool stains out of my area rug. It also has a stain guard which protects it from further damage. No strong chemical smells like some other formulas I've used in the past. I'm happy to say our area rug is stain free :)
