Greenwald's Carpet, Upholstery & Fabric Stain Remover is an environmentally friendly cleaner. With refills, you're not throwing away empty bottles every time you use up cleaner. With this cleaner, you simply refill your bottle. This is an easy to use stain remover. Fill a 32oz. spray bottle with warm water. Drop in one packet and let it sit for one minute. Then gently shake and it's ready for use. This has been a great stain remover. I've used this on upholstery and carpet. After spraying the stain, I'll let it sit for a few minutes then scrub. The stains came right out. I'm highly impressed with the results. It doesn't leave rings or stickiness. It's definitely a commercial grade cleaner at a very affordable price. You get 6 water-soluble refills with a purchase which really saves money rather than buying individual bottles of cleaner. It also comes with 100% money back guarantee. Great product!!
