Good for stains. I have been using for 12 years. However, there use to be vendors and the local grocery store. That stopped now everything is online.

Excellent product. I cleaned the car with it and noticed a smell was gone so I used it on pet stains on my carpet in the house. Smells and stains are gone. I’ll never be without it. Best carpet cleaner I’ve ever found.
