How Pet Stain Off Works
Pet Stain Off contains beneficial bacteria and enzymes that begin breaking down organic contamination under suitable conditions. The bacterial cultures consume the organic material responsible for many pet stains and odors.
Unlike a fragrance-only deodorizer, this product is designed to reduce the odor source itself. Adequate moisture, warm temperatures, proper dilution, and sufficient dwell time help support the biological digestion process.
Older, heavily saturated, or deeply contaminated areas may require repeated treatment. Carpet backing, padding, subflooring, upholstery filling, and other concealed materials may also require direct treatment when contamination has penetrated beneath the visible surface.
Carpet and Upholstery Applications
Pet Stain Off can be used with several professional cleaning methods, including:
- Pump-up or hand sprayer application
- Carpet extraction cleaning
- Bonnet cleaning
- Manual spot treatment
- Pet-odor remediation procedures
Always inspect and test the material before widespread application. Apply enough mixed solution to reach the same depth as the contamination. Surface-only treatment may not completely correct odor originating in carpet backing, padding, subflooring, upholstery cushions, or other concealed materials.
Directions for General Odor Control
- Remove loose waste and excess contamination.
- Clean or blot up as much removable material as practical.
- Apply the properly diluted product directly to the source of the malodor.
- Apply enough solution to contact all contaminated material.
- Keep the treated area moist for at least 30 minutes.
- Allow the bacterial and enzyme action sufficient time to digest the organic residue.
- Repeat the application when dealing with heavy or deeply absorbed contamination.
Directions for Carpet Treatment
- Vacuum the carpet thoroughly.
- Spot-clean and remove loose contamination before applying the treatment.
- Mix Pet Stain Off according to the level of organic contamination.
- Apply with a pump-up sprayer, hand sprayer, or compatible carpet-cleaning equipment.
- Keep the treated area moist for a minimum of 30 minutes.
- Allow additional dwell time for severe or older contamination when appropriate.
- Extract or complete the cleaning process according to the surface manufacturer's recommendations.
Recommended Dilution
| Application |
Dilution Ratio |
Product Per Gallon of Water |
| Light organic contamination |
1:16 |
8 ounces per gallon |
| Heavy organic contamination |

16 ounces per gallon |
When used in compatible carpet-cleaning equipment, use approximately 1/2 pint to 1 pint per gallon of mixed solution, depending on the severity of the contamination.
Estimated Mixed-Solution Yield
| Dilution |
Concentrate Used Per Gallon |
Approximate Yield From This 4-Gallon Case |
| Light contamination |
8 ounces |
Approximately 64 gallons of mixed treatment |
| Heavy contamination |
16 ounces |
Approximately 32 gallons of mixed treatment |
Actual coverage will vary according to surface porosity, application method, contamination depth, and the amount of solution required to reach the odor source.
Optimum Conditions for Biological Activity
- Effective pH range: approximately 6.0 to 9.5
- Optimum pH: approximately 7.5
- Warm conditions generally improve bacterial activity
- Product activity is retained at temperatures up to approximately 130°F
- The treated area should remain moist long enough for biological digestion to occur
Do not combine Pet Stain Off with strong acids, caustic cleaners, chlorine bleach, disinfectants, sanitizers, oxidizers, or other chemicals that may destroy or reduce bacterial and enzyme activity.
When another cleaning chemical has already been used, rinse the affected area thoroughly and return it to a suitable pH before applying the biological treatment.

Important Application Notes
- This product must contact the actual odor-producing material to work properly.
- Apply enough mixed product to reach the full depth of the contamination.
- Do not expect a light surface mist to correct contamination located in carpet padding or subflooring.
- Maintain adequate moisture during the required dwell period.
- Do not use boiling water or expose the bacterial treatment to excessive heat.
- Do not mix the concentrate with incompatible cleaners or disinfectants.
- Heavy contamination may require repeated treatment.
- Test delicate fabrics, upholstery, rugs, and color-sensitive materials before widespread use.
Frequently Asked Questions
Is Pet Stain Off only a deodorizer?
No. It is a biological stain and odor treatment containing bacteria and enzymes designed to digest organic material responsible for many persistent odors.
Does it simply cover pet odors with fragrance?
The product does contain a fragrance, but its principal purpose is to digest odor-producing organic contamination rather than merely covering the odor.
Can it be used for both urine and fecal contamination?
Yes. The formula is intended to treat organic residues including urine, feces, vomit, and other animal-waste contamination.
Can it be applied through a carpet extractor?
The manufacturer states that it can be used with compatible extraction equipment. It may also be applied separately with a hand or pump-up sprayer.
How long should the product remain wet?
Keep the treated material moist for at least 30 minutes. More severe contamination may benefit from additional dwell time.
Will it correct urine that has soaked through the carpet?
Only when the mixed treatment reaches all contaminated materials. Carpet backing, padding, tack strip, subflooring, baseboards, or wall materials may require separate treatment or replacement.
Why might the product fail to work?
Common causes include insufficient product, inadequate dwell time, allowing the area to dry too quickly, failure to reach the contamination source, incompatible chemical residue, extreme pH, or contamination that has penetrated materials that were not treated.
How much product is included?
This listing includes four one-gallon bottles for a total of four gallons.
