Prochem All Fiber Deep Clean Rinse - Professional Acidic Low pH Carpet Cleaning Solution for Commercial & Residential Use, 1 Gallon (S103-1m) | Perfect for Deep Stain Removal, Upholstery & High-Traffic Area Cleaning

Used with bissel 2x proheat revolution pet and it worked very well. Glad it does not leave residue- next time I am going to spray with a garden weed type sprayer and only use water to clean or rinse - better for the carpet. Try not to put cleanser in any carpet cleaner. So I’ve been told by a professional. I had to pretreat stains with a concentrate of the same solution and it worked nicely. Use fans if you can to prevent wicking.
