Harvard Chemical Free Rinse Pro TC220 is a professional acidic carpet rinsing agent designed to neutralize alkaline detergent residues left behind after hot water extraction cleaning. By restoring carpet fibers closer to their natural pH, Free Rinse Pro helps reduce rapid re-soiling, leaves carpets feeling softer, improves appearance, and helps prevent browning and color bleeding.
Unlike plain water extraction, using an acid rinse removes detergent residue that can attract new soil. Professional carpet cleaners frequently use an acidic rinse as the final extraction step for both residential and commercial carpet cleaning.
Always pre-test in an inconspicuous area before cleaning any carpet, rug, or upholstery.
Most professional carpet pre-sprays are alkaline because they dissolve oily soils extremely well. After cleaning, however, alkaline residues left inside carpet fibers can continue attracting dirt if they are not neutralized. An acidic rinse helps restore the carpet to a more neutral condition, reducing residue while improving softness and appearance. Many experienced carpet cleaners consider an acid rinse to be one of the most important steps in professional hot water extraction. :contentReference[oaicite:0]{index=0}
