Cleaning carpets, tile, and upholstery with the patented Zr Water process — softened tap water that is alkalized and ionized to rinse without soap or detergent residue — Zerorez Carpet Cleaning has operated its San Diego franchise from 3200 Fourth Ave in Hillcrest's 92103 block since 2002. Every technician holds the Institute of Inspection Cleaning and Restoration Certification (IICRC) Carpet Cleaning Technician designation, and the franchise's air-duct division overlaps directly with HVAC specialists such as SD Ductmaster Cleaners on combined carpet-and-duct refreshes. The three-step process starts with an orange-peel pre-treatment, followed by counter-rotating Zr Lifter brushes that dislodge embedded debris, and finishes with the enclosed Zr Wand for high-suction rinse and fast drying. The cleaning system carries a Platinum Rating from the Carpet and Rug Institute, the CRI's highest seal of approval. Pre-listing carpet refreshes and tile-and-grout sealing for properties moving through agents such as Antoinette Embry, REALTOR® | Compass sit alongside residential maintenance accounts and one-time deep cleans. The largest jobs cover full-home carpet, tile-and-grout color sealing, upholstery, and air duct cleaning together as a single integrated appointment.
