Concentrated Carpet Neutralizer. Accumulation of alkaline films imbedded in carpet fibers can cause carpets and fabrics to look dull, yellow or hazy. This effect can be a result of over using high pH shampoo, extraction solutions, ice melt residue, urine salts, coffee, teas, juices or other alkaline residues. Brown Out will remove and prevent the yellow-brown stains caused by using good quality cleaners. At the same time, it will act as a final rinse to remove the last soil and detergent to complete the cleaning job. To eliminate this film, use at a dilution of 2 - 4 ounces per gallon of water and spray onto the affected area(s). This product may also be added to shampooing machines, carpet extractors and bonnet solutions and applied during the cleaning process. Do not mix with other products.
