My recipe for getting your carpets clean. 1 cup of distilled white vinegar, 2 gallons hot water, and 1/2 to 1 cup of Borax, diluted. This got our carpets SO clean and fresh! Never hiring a company to do it again! I even had red marker on my carpet that the "other guys" said would never come out; this got it out! I save some in a mason jar for emergency spot cleaning.
This is a guide about removing red wine stains from carpet. If you drink red wine then you know that spills are going to eventually happen and they are very difficult to clean up. Red wine stains are one of the hardest stains to remove from any fabric.
