Shop for Appliances at The Home Depot. 3-in-1 Carpet Cleaner is a revolutionary concentrated carpet cleaner specially formulated to be 3 products in 1: (i) a Traffic Lane Pre-treatment for Sprayer or Bonnet Cleaning Applications, (ii) a Spot Remover and (iii) an Extraction Cleaner. No need for separate pre-sprays or spot removers. Just mix with water according to the directions for the desired application. Each dilution safely cleans carpets without the use of detergents and harmful chemicals, thus eliminating the need for defoamer or additional rinsing agents. Unlike traditional carpet cleaning formulations, which promote re-soiling, fiber untwisting, matting and longer drying times, our detergent-free technology suspends dirt and soils, reducing wear and damage to carpet appearance.
