I have a 8x8 dirt area covered in tanbark where my 4 German Shepherds potty and urinate. I will have an open house soon and need help eliminating the urine smell. I removed the tanbark and watered the entire area so far. The smell is really strong. Also what can I do to the area to keep it smelling not so bad as my dogs contine to use until I sell.
My normal process is to pick up poop immediately since its a small area.
Steam cleaners sell "spot" enzyme product that naturally breaks down urine and poo... I had used that in the past to prevent dogs from using the same area in and outside of the house. works great on Carpet and I had to use it on a deck corner where boys kept marking...so if all fails try that.
the smell is from the uring being broken down. Those enzymes break more down, so the smell will get a bit stronger before it goes away. If the open house is soon, it might backfire, just something to keep in mind.
I have used a solution of vinegar and water which I spray over baking soda to help eliminate the smell. My dogs like to urinat right at the back door and does not smell to pleasent so I do this about every two weeks, more in the summer.
I put down pea gravel in the dog areas (not a good idea) and when I would wash the area, I used some dawn soap put in in a garden sprayer (used to spray insecticide) and sprayed the entire area. Let dry then washed again. It was not a quick fix however and took a couple of apps.
There is a product that is called "Kid's N Pets" believe me this really works like it says it does. I used it on a rental that had cat urine odor so bad after I pulled the carpet and pad that I thought I would have to remove the sub-floor. I used this stuff and in 24 hours the odor was gone and did not come back!
