Pet urine is the call that decides whether a carpet cleaner gets referred or gets a refund request. Enzyme products need the right temperature, the right dwell, and a living organism to survive the trip to feed on the deposit. HydraMaster USR with MultiPhase takes the other route: activated oxygen chemically modifies the stain and the odor-causing compound directly, so the result does not depend on keeping bacteria alive in a bucket. Professional carpet cleaning and restoration technicians use it on urine-contaminated carpet, rugs, and upholstery where the customer wants the smell gone, not covered.
The formula pairs oxidation with MultiPhase, HydraMaster's encapsulating and bonding odor eliminator, so two mechanisms run at once. Oxidation breaks down the chromophores that make the yellow stain visible and deactivates the odor compounds. MultiPhase encapsulates and bonds what remains. Because the odor is chemically eliminated rather than masked, there is no heavy perfume left in the room afterward, which matters in homes where the customer is already sensitive to smell. Added penetrants help the solution reach the deposit down in the backing, and anti-resoiling agents keep the treated area from graying faster than the carpet around it. This case ships four 6.5 pound jars.
Built for these jobs
- Pet urine stain and odor treatment – The primary job: yellow urine staining and the ammonia odor that comes back on humid days.
- Sub-surface extraction work – Mixed hot and applied at volume, it is designed to be flushed with a sub-surface tool that reaches the pad and backing.
- Rug and upholstery odor calls – Handles urine deposits on area rugs and upholstered furniture where replacement is not an option.
- Restoration and post-loss deodorizing – Useful anywhere urine contamination is discovered during a water or trauma job.
- Second-pass treatment after a failed enzyme – Works where an enzyme treatment did not hold, because it does not rely on live culture activity.

Frequently asked questions
How do I mix and apply USR with MultiPhase?
The common professional method is to mix the manufacturer's recommended amount, about 6 ounces, into a five gallon bucket of very hot water, apply, allow a 10 to 30 minute dwell, then extract. Longer dwell generally gives a better result. Always follow the current label directions for your application.
Why oxidation instead of an enzyme?
An enzyme product depends on living organisms reaching and consuming the urine deposit, which requires favorable temperature, dwell time, and moisture. Oxidation chemically modifies the stain and odor compounds directly, so the outcome is less dependent on field conditions.
Will it leave a strong fragrance behind?
No. The product is built to eliminate odor chemically rather than cover it, so it does not leave the heavy perfume that masking deodorizers do.
Is it safe on wool or delicate fibers?
Oxidizers can affect dyes and some natural fibers. Always test in an inconspicuous area first and follow label guidance for fiber type before treating wool, silk, or a decorative rug.
Do I need a sub-surface extraction tool?
Not always, but urine that has soaked into the pad and backing will not be reached by a standard wand. For deep contamination, a sub-surface tool is what actually flushes the deposit out.
