It just depends on how much she used that spot. Back ground, I used to have a terible problem with skunks. And a couple of times a year my dog would tangle with one. The smell would get into everything (we lived in a house built in 1906, so it was fairly open to drafts. Once my dog got into the house just after he tangled with at skunk. He rubbed himself on a rug we had among other things before we could get him back outside.
Because of that we learned that most of grandmas home remedies are just myths perpetrated by those that scrubbed it out finally, and want to tell you their special secret.
I know the secret. You must oxidize the cat urine. This will require you to moisten the area with plain water, tehn vacuume it. Dont get it wet, just moisten it. Keep doing this until your white rag gets cleaner when you dab it. you will have to do this several times. You might need to put in a few drops of a mild dishwashing soap into your water. Now here comes the real part of the secret. Sunshine!!!!! Sunshine is an oxidizer, just like bleach. Leave it in the sunshine for a couple of days. The UV rays will break up those molecules that is causing it to stink. You might have to repeat this process a few times and it may take 3 or 4 days. But sunshine will beat up those smelly molecules.
I hope this helps........
Over the winter, our kitty somehow got locked in the camper for a couple of weeks. Out of the whole camper for her to use as her bathroom she decided to use the small couch in our slide that also contains our pull out bed. We have treated and treated and treated and the smell will not go. Of course this couch at attached to the slide and the cushions can not be removed.
any helpful tips? Besides replacement...
