PURT VS ENZYME TREATMENTS: WHAT’S THE DIFFERENCE?
We get asked this question often - especially when someone has tried a pet enzyme spray and it appeared to work at first and then a few days later the urine odour is back.
The answer is not simply the product being used. It is whether the entire urine deposit is located, reached and properly treated.
Enzyme treatments can work when the correct product reaches all of the contamination and remains under suitable conditions for long enough. However, enzymes and beneficial bacteria depend on factors such as moisture, temperature, pH and dwell time. Previous cleaning chemicals, disinfectants or premature drying can also affect their performance.
The challenge is that pet urine rarely stays on the surface. It can pe*****te the carpet fibres, backing and underlay, sometimes reaching the subfloor.
That is why Chem-Dry Metro treats urine contamination as a professional restoration job, not simply a standard carpet clean.
Our comprehensive process includes:
• Using specialised equipment to locate hidden contamination
• Rinsing and extracting the bulk of the urine residues
• Applying PURT deeply enough to reach the remaining source
• Allowing its oxidation-based chemistry to break down the odour-causing compounds
PURT uses three odour-control components, including an oxidiser that breaks odour and stain molecules into smaller compounds. Its molecular-entrapment technology also helps neutralise odour compounds and reduce unpleasant off-gassing while the treatment is working.
Unlike a biological process, oxidation does not depend on keeping microorganisms alive.
This specialised product, combined with accurate detection, thorough extraction and correct application, is why PURT can deliver more consistent results on severe, aged and previously treated urine contamination.
Pet urine odour should be treated at its source, not simply covered with fragrance.
