Browning Treatment, 1 gal
Pro's Choice "Browning Treatment" (formerly known as Brown Out) is an excellent treatment for water stains on upholstered furniture, yellowing of white furniture caused by wet cleaning, and treatment of brown out on carpet due to over-wetting.
Simply apply full strength to the problem area. The full benefits of this treatment may not be realized for several hours. Very often you will see the stain disappear nearly immediately as you watch.
