3 Ways to Remove Urine Odor from Concrete - wikiHow
the reciepe for pet urine odor removal in concrete basement floors
When I moved into my new house the prior residents had both cats and dogs that urinated on the carpet. So when we moved in my little dogs peed all over the carpet also. We had to pull up the carpet and when we did we found out that there was rough concrete underneath. Well my dogs still pee on the carpet. I have used Pinesol and bleach it works for like a day then the smell comes back. What else can I use to get rid of the smell? I read that there was something that could break down the chemical make up of the urine and maybe keep the smell out of the concrete. If anybody could help me with this problem I would really appreciate it. Thanx Cleaning process for removing pet urine stains and odor (dogs, cats, and male cat spraying/territorial marking) specifically for concrete; recommended by vets, is an enzymatic based cleaner, "Urine-Off Stain and Odor Remover (Veterinarian Strength)." Process for use... (1) First thoroughly clean the ENTIRE concrete surface with 2-1 solution of Vinegar and Water; wet the ENTIRE surface with it, scrub, rinse, allow to dry. (2) Spray the "Urine-Off Stain and Odor Remover" over the concrete, really wetting it out with this enzymatic cleaning solution. Lay plastic over the wet surface to control evaporation; allowing it to work longer and giving it more time to really penetrate down into the urine stained concrete. Leave this for few hours. Then rinse the floor. You can usually purchase "Urine-Off Stain and Odor Remover" from PetSmart, Petco, and possibly some janitorial cleaning supply stores. After doing so recommend that the concrete be sealed against any type of topical moisture intrusion again, since if/when the surface get moisture down into it again (of any type) it can release what is left of the old urine that permeated deeper down into the concrete (in which case, the property owner would need to go through steps 1 and 2 again).If they don't care, or take the time, to house break their dog, allowing it to use their floor like a cat uses a litter box, then they will have to deal with potential stains and offensive urine odor. Guess if they miss the toilet and pee on the bathroom floor themselves they would just leave it to migrate into the polished concrete floor as well. Their stance of "don't care if dog pees on the floor" is not only unsightly and unsanitary, but it is simply offensive; furthermore, they are "allowing their own dog to vandalize their floor" without caring to do anything about it accept to moan/complain about the results (staining and odor) to you. I've been reading the posts about how to remove pet urine from concrete. I think my situation may be a little different and I was hoping somebody could help. I live in a loft and have polished concrete floors, they aren't sealed. Unfortunatley I have some stained concrete from my dog (she has urine accidents) and cat (he leaves hairballs)!!!!! We've tried a few citrus cleaners but they seem only to fade the stains and leave them still noticable. All the info I've found has been for sidewalks, basement floors, or industrial areas. There isn't an odor any longer so, will the vinegar do the trick for stains too and what about stains that have been sitting. Please, any help would be greatly appreciated. Thank you
