I am trying to eliminate cat odor from an upholstry couch cushion.
I have tried the oxygenated cleaner, but still have an odor.
Thursday’s Answer:The foam inside a farbic-covered cushion is extremely difficult if not impossible to properly clean, deodorize and sanitize.
If the cushion has a zip off cover, replace the foam. If there is no zipper, you may want to take the cushion to an upholstery shop and have the foam replaced and then have the fabric cleaned and deodorized.
If the fabric is available it may be easier and cheaper to have an upholstery shop recover a new cushion for you.
Other possible cleaning/deodorizing methods to reach the affected area of an open cell foam cushion include: injection, saturation and Ozone treatment.
Injection requires inserting a hypodermic syringe into the contaminated area and injecting approx. 3 ml of an odor counteractant treatment into each square inch of foam.
The injection solution should be a high quality protein enzyme, formulated for urine odor removal.
Then, re-clean the fabric and place in direct sunlight for 8 hours.
Saturation requires pre-testing ... Gary Clipperton, president of National Pro Clean Corporation
