Simply drop two pre-measured yellow Carpet Pre-Spotter PAK-It into its matching yellow quart trigger spray bottle (sold separately) and add cold tepid or warm water. Wait two minutes and shake. Adjust nozzle to mist or stream settings and spray liberally onto stain. Allow the product to sit on the stain for one to two minutes to absorb the stain. Rub gently with a hand brush then blot with paper towel or cloth. Repeat if necessary until stain is removed. Finally rinse with a little clean water and blot dry. If using a carpet steamer or extractor spray on stain before use. Note always test for colorfastness on an inconspicuous surface area. Note: This is the only PAK-IT Quart Bottle product that requires 2 PAK-Its not 1.
