Recently I spoke on the phone with a long-time customer of Nok-Out who told me a story from her workplace. They had a temporary worker – a volunteer – who had an untreated incontinence issue. She leaked a little bit of urine somewhat regularly as she moved around in the office area, sitting in different chairs to do different jobs. The cushioning in the chairs was absorbing the urine and once bacteria get a hold of that urine as a food source, the chairs start to stink. The caller was purchasing some Nok-Out to eliminate urine odor from those chairs. It got me to thinking about the difficulty in treating foam cushioning. Here is how to treat smelly cushions for odor – including urine odors.

Problem: Nok-Out works when it comes into direct contact with the odor source. In fact, it can ONLY work, when it is in direct contact with all of the odor source. If you miss a bit of the source, then that missed place will continue to stink. Cushions are thick and are not necessarily as absorbent as a sponge, so it can be a bit of a challenge if urine or other smelly stuff has penetrated deep into the cushioning. How do you get Nok-Out to work for you in this case?

Solution 1

If possible, remove the cushion from the covering. There may be a zipper in the back and if you are lucky, you can pull the foam cushion out and put it back later. You will need a largish tub. It doesn’t necessarily have to be as large as the cushion, but it should be big enough that you can ‘dunk’ large portions of the foam in it. Add water to this tub,and then add Nok-Out. A dilution ratio of 8 water to 1 Nok-Out will work here and will be efficient. Dunk a portion or all of the cushion in your mixture and palm flat, squeeze it down slowly, forcing the air out. Then slowly release the pressure, allowing the diluted Nok-Out mixture to be drawn into the cushion. Do this a couple of times. Treat the entire cushion in this way. This will both rinse away the dried urine and will leave a bit of Nok-Out behind to eliminate the urine odor. Allow it to dry and put the cushion back into its covering. This is the easy, most reliable method.Unfortunately, not all cushions can be removed from the covering. So another plan may be required.

Solution 2

Even if you can’t get direct access to the foam, you still need to get Nok-Out to penetrate deeply into the cushion to achieve direct contact with any urine source deep in the cushions. But it is not efficient at all to just pour Nok-Out directly on the seat or sofa. We can, however, dilute Nok-Out at a dilution rate ranging from 4 to 1 to the same 8 to 1 in the ‘tub’ method. Put this diluted Nok-Out into a sprayer and go to town on that cushion! Spray heavily. Wait a few minutes for it to be absorbed – and spray again. And maybe again and again as needed, to get this dilute Nok-Out mixture to penetrate deeply. Much like ‘lather, rinse and repeat’, you may have to go through this process more than once to be successful.

Why not just spray the cushions directly with Nok-Out?

You can, but your success will depend on how deeply you can get Nok-Out to penetrate into the cushion material. However deep the urine went, Nok-Out needs to get there also.

Will this work for pet urine also?

Yes indeed. At some level, urine is urine, whether dog, cat, ferret, pot-bellied pig or people. Nok-Out will work as long as it comes into direct contact with the odor source. It will remove ALL the odor if you can get it to come into contact with all the smelly stuff.
