This stuff worked better than I had hoped! Took out set in stains including pizza sauce that I never thought would come out. The only negative is the spray pattern makes it hard to do even coverage and it goes all over when spraying

This product is amazing. I’m a sales rep and I work out of my car, therefore my car seats need to be cleaned more often than most. This product get out every stain and cleans extremely well. I use it for my sofa and rugs when needed. I even sent it to my daughter in college to clean her couch.
