Description
Pro’s Choice CSS is a color-stabilizing sour for carpet and upholstery. Use it after alkaline stain removal to bring fiber pH back down, steady the dye, and limit browning on natural fibers as they dry.
It is the follow-up step with wool stain systems such as Red Relief for Wool and Stain Magic for Wool. Those products lift the spot. CSS neutralizes the leftover chemistry and stabilizes textile color.
On carpet, rinse and extract after stain removal, saturate the fibers with CSS, wait about 3 minutes, then extraction-rinse and blot. Faster drying gives a cleaner finish. On upholstery, dilute 4 to 1 with water and apply before cleaning with a high-volume trigger sprayer or a pump sprayer fitted with an 04 tip or smaller. Light brushing helps it reach the yarn.
Test an inconspicuous area first. Do not mix with alkaline cleaners in the same tank.
