Alkaline Pre-Spray is the most versatile traffic lane cleaner available. Alkaline Pre-spray is designed to be used regularly for traffic lane preconditioning. Dilute it to proper strength, spray it on the carpet and watch the soil and stains begin to melt away. Alkaline Pre-spray begins immediately to separate soil and grease from the carpet fibers. While maintaining a safer pH designed for nylon, Alkaline Pre-spray will readily remove soils like no other traffic lane cleaner in its class. Safer and effective for stain resistant carpets.
