Tip: Baking Soda For Urine on Wood Floors

The best idea for soaking pet urine from the cracks in the wooden floor is to sprinkle baking soda on the boards where needed. Leave it for an hour or two and you will actually see the urine sucked up like a straw. You must repeat this a few times.

I had this when we bought our home too. There is a bottle of cleaning solution that you can buy at Lowes (probably home dept too) I can't remember the name of it, it comes in a black jug. It has a I skull on it and it had "40" in the name. Anyway its a very strong cleaning solution but the smell is very mild, pour it on your floors with very hot water and take a deck scrubbing brush to it as it will take the stickiness and most of the stain up. to get rid of it completely you will have to sand and refinish. your floors.

Just remember to dry your floors quickly with a towel when finished. you don't want your floors absorbing that water.
Hope this helps! Good luck.

If the cat is not using the litter box, take it to the vet. It probably has a uti. If this is an old odor attracting your cat, you must get rid of the odor. I would try Nature's miracle. Spray liberally onto the stain. Keep it wet. At first it may smell worse, but after a few days, it should completely remove the smell and most of the stain. After initial application, wet clean cloth with Nature's miracle and keep it over the stain. This will help keep the application from drying out. Then, if your floors are oiled instead of polyurethane, it will be an easy fix. If not, you may have to sand and redo that area. You must make sure all urine is gone first! A black light will tell you.

Question: Does Dog Urine Stain Hardwood?

I'm getting a new puppy and have all hardwood. It is an old house so the hardwood is real wood not the new laminate they have. Will urine cause any stains on the floor? Even if I should get it up quickly? I can't potty train her for another month because she is only 2 months old. Thanks.

Every time that your dog goes into the yard and does the deed, immediately hand her/him a treat. This only takes four or five times. I broke two in a week with this. You can pick up underpads in the incontinence section of discount stores and place them by the door if you don't get there in time, and in a crate so you don't have to wash as much. They have them in pet stores, but the are twice the price.

You mentioned hydrogen peroxide to remove pet stains from wood floors. This does work, but a couple notes; unless you said otherwise you are probably using household 3% solution. You can purchase near 100% peroxide at Home Depot or some such. But be careful, at that strength it will burn you, and you are looking at bleaching the wood. Which means the finish, or any color stain are all dissolved, along with the stain hopefully. The wood will need to be refinished. This is not to detour but FYI.

When I bought my home one floor was heavily stained. I finish floors for a living, so I bleached the whole area, stained it a darker color and refinished the floor. At that point it was unnoticeable. Since, I have re-sanded the area and gone to a natural finish. The few remaining blotches are difficult to distinguish from the natural variation in wood color and grain.

This was the result starting from deep old heavy pet stains. Lesser stains may be easier to deal with, needing only local light sanding and a little touch up refinish. It stained because, whatever, got through the finish and into the wood grain.

Also, when we tear out a carpet to install wood, oft times pet odor has gotten into the sub-floor (the ply wood or particle board underneath the carpet). I can still smell it after the wood has been lain over the top, the polyurethane may seal the odor in, but you may consider painting KILNS or some other stain cover to seal the sub-floor before wood instillation.

One beauty of wood is that it is durable, with care can last years and years, is low maintenance, and for the most part can always be fixed.

I had the same problem with a cat. It took a while to realize that the cat was peeing on the rug and that it was soaking into the hardwood underneath. When we lifted the rug, there were black spots in several places. Having removed the rug, the hardwood floors looked nice enough to try to restore, so I tried oxalic acid and other recommended remedies. The spots lighten up some, but in the end the spots never clear up enough to look decent. You will likely need to get the floors sanded and refinished.

We had a similar problem in a new to us 50 year old house that we only saw on summer days with all doors open. Upon moving in, we found that the previous owner's dog left dark stains that smelled very bad and were all over the house. There were also older stains. After many valiant tries to clean out the stains and odor using all types of cleaners, all failed as the stains and especially the odor had seeped down into the wood. We finally replaced the entire oak floor. We filed against the previous owner who eventually reimbursed the replacement costs. Good Luck!

Is the oak sealed? If so you can buy wood cleaning products and mix with water. If it's sealed you can also try white wine vinegar with water. If it's not sealed the trick is to use as little water as possible. Water can warp oak.

Also it's important to mop with the grain.

We had animals the past 27 years and had run into problems with only one house we rented. We used this product called odor be gone , you soak the wood once it drys you paint this other product called kills . This works permanently. They also make odor be gone in a carpet shampoo I still mix some odor be gone into the shampoo to make it stronger it works great . You may have to repeat it a few times but it will work. You do have to treat the wood and replace padding for best results. You can find this at Home Depo , that's where we found it. Good luck Penny Berry.

      Does anyone know how to remove set in pet stains (urine) from oak hardwood floors? The stains are dark, almost black. They are in a rental property and may be up to a year old. Thank you.


      Urine Stains - Hardwood floors 05/29/2005
      While finding this site, checking with wood flooring stores, and the local PetSmart, We accidentally found a solution to the urine stain problem:

      Fill a squirt bottle with full strength Hydrogen Peroxide from the drug store. (The solution is about 3.5% out of the bottle). Squirt the stain and let rest for about 1 minute. You will now be able to easily scrape off the varnish. Apply the solution again liberally. Let it react for at least 2 hours. Depending on how old and how dense the stain, you may have to sand the spot and reapply the peroxide several times. Then it will be necessary of course to refinish the spot.

      We have just sanded and refinished a large hardwood floor that has been under a wall to wall carpet for 14 years. Imagine our delight to see blackened urine stains fade away with this process...

      they said PEROXIDE, not bleach. Peroxide bleaches your hair, but it's not CHLORINE bleach, which gets your whites clean.

      RE: Pet Urine Stains On Hardwood Floors

      I tried the hydrogen peroxide and covered it with clear plastic wrap to hold the moisture in longer and when I woke up the next morning (approx. 9hrs later), almost all the dark black was gone. Now the stain is a faint green hue. Repeating to see if the rest will come out. (07/02/2006)

      RE: Pet Urine Stains On Hardwood Floors

      We are getting ready to sell our condo, which has the "pre-finished" (meaning not enough varnish to matter) oak floors and we had a couple pet urine stains and a couple places where someone put a damp mop and left it (our son did it-not me!!). I tried just bleach and it helped some, but dark stains along the cracks still showed, so I tried one further step: I poured some hydrogen peroxide on the stain and let it sit for a couple minutes, then I poured full strength bleach over it, combining the two liquids. It REALLY foams! Be careful and don't wear good clothes, or they might get bleached! I left the foamy stuff on for about 5-10 minutes, then took my string mop and mopped most of it off, leaving it slightly damp. It looked better right away, but by the next morning (I did it in the evening), the stains were gone. I don't know if the combination is doing the job, or just one or the other worked, but I'm not complaining. A long time ago, I bought a commercial wood bleaching kit, and it was a solution of lye, which you sprayed on the wood to soften it, and then some strong peroxide, which caused MAJOR foaming, and did the bleaching. I thought that maybe this might work too, being two strong oxidizing solutions. (07/17/2006)

      Editor's Note: Mixing bleach and hydrogen peroxide will make toxic chlorine gas and could cause injuries. Please use caution and do research before mixing different cleaners.

      Regular old cat litter, piled on the stain. I used the clumping kind, you could literally see the litter turn yellow as it soaked it up.

      I had to do it a couple of times, but it worked for me. Anything liquid is just going to make the wood wetter, defeating the purpose. (11/07/2008)

      RE: Pet Urine Stains on Hardwood Floors

      I had the same issue, wherein I removed carpet in an older home to find nasty black last-owners' animal urine stains marring the gorgeous hardwood floors. After frustratingly sanding with an orbital sander, I was unable to remove them hardly at all. I then covered the entire black-stained area with paper towels, and next soaked them with Hydrogen Peroxide. I covered the entire affected area with a couple of garbage bags to seal it in, and let stand for about an hour. Repeated 2x, since it was really bad.

      I pulled the stuff off, and wiped semi-dry with more paper towels, and covered the entire area with extra sanding-dust from the dust collector of the sander, to sop up the remaining moisture. I vacuumed the moist dust up, let it dry fully in the air, left for a couple of hours, and came home to see that the stain was completely gone! Amazing super-cheap solution! (08/13/2009)
