What is the best way to clean dog urine?

I use an oxygenated cleaner (Awesome Orange- my favorite and OxyClean) and water to scrub the stain and remove the odor so they don't want to use the same spot. After it dries, pour baking soda on the spot for further removal of the scent.

Vinegar and water mixed 50/50 and either poured or sprayed onto the stain is a good start. This will kill the odor and reduce the chances the dog urinates in the same spot again. Blot with paper towel to soak up as much as possible and use a shop vac or some other wet-vac system to get as much liquid up as possible. Repeat if the stain is especially deep.

If staining persists in the material, you can try a very mild soap mixture and lots of scrubbing. Test in an out of the way area to make sure it doesn't discolor the material you're cleaning. Good luck.

I have used a combo of vinegar, dawn, and diluted with water scrubbed into the carpet, let sit for 20 minutes and cleaned again with just water. Soak up the moisture. When dry I added a combo off baking soda and salt to remove excess odor and bring the resilience in the carpet back.
