Core's Tann-X coffee and tannin stain remover effectively attacks both coffee and other natural tannins found in tea, cola, wine and urine. It modifies and reduces the stain color intensity with a pH of 4.5. Great for use on clothing, carpeting, or any type of area that may stain, including countertops. We do have another food & beverage stain remover, but it is geared more towards protein based stains. Take a look at our complete line of carpet & laundry based spot removers, for other options.
