When you have pets accidents happen, even on your beautiful hardwood flooring. This is a guide about removing pet urine stains from hardwood floors.
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.

I have two Dachshunds that have made it their business to ruin me. I don't have the money to replace these parquet tiles and knowing the maintenance of my building they will charge me three times what it's really worth. How can you clean up and get out dog urine stains and odors from this type of flooring. I'm desperate! Please someone help!

What a snooty answer from someone who doesn't know how notorious Weiner dogs are for this behavior. Geesh.
Try the hydrogen peroxide.. And ignore the rude person. Sorry you got trolled for such a simple thing.

Please tell me more about the peroxide soaked paper towels for pet urine stains. I rent and have an elderly dog with bladder issues and when I pulled up my rug today there is a rather large black stain on the hardwood floors. I need to clean this up before the end of our lease. Please help!
I just pulled out the carpeting and padding from our rental house bedrooms and living room and I have tons of large urine spots on the hardwood floor. I'm sick about it. Please help. i don't have any idea where to start.
Looking forward to your reply.

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.
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 pulled up the carpet in my living room today and I had black spots on the floor that smelt like pee. I need a solution to kill the smell take the black spots away.

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.
About 2 months ago we paid a lot to have our hardwood floors refinished. Now I have a black stain on the floor from cat urine. Is there any way of getting the cat urine black stain off the wood floor without ruining the finish? Thank you for any help.

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 enzyme cleaner. 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.
I had a tenant, had being the key word here, with a no pet lease. Three dogs and a cat later, my hardwood floors are a mess. I do not think the animals were let out, it is disgusting. I am hoping for a Nature's Miracle recipe for hardwood floors. Thank you!

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.
I have a old home and am trying to do work on the floor. It has a whole lot of pet stains. I want to keep the floor. How do I get it out? Please help. No work on them has been done for 25 years.

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!
My oak floor is stained by my dog being sick on floor in the night. It is dark brown in color and the size of a medallion. Can I ever remove this? I have wiped it over and it doesn't budge.
November 27, 2014
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.
How do I repair pet stains on a wood floor? Is there a way to restain just were the pet stains are?
November 6, 2014
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.

How do I remove dried urine spots from hardwood?
I had a black garbage bag full of clothes on my hardwood floor and I had it there for about a week, while it was there my two dogs were lifting their leg on it and I didn't realize this until I picked the bag up and behold a pretty big dark spot on my hardwood floor. Please can someone tell me how to get this out without having to sand and refinish?
Over several years two male cats peed in a particular place in our living room. Will refinishing the floor ever get rid of the stain/odor? Or, should I use KILZ on the floor and put down new flooring?
By Barb R.
Our dog was peeing on the area rug in our dining room which went unnoticed for a period of time. When discovered we took the area rug in for cleaning, but found dark stains on the hard wood floor underneath the rug and pad. Any suggestions for removal of spots and smell will be greatly appreciated?
Will hydrogen peroxide bleach the timber floor lighter? We have dark mahogany floors. Will hydrogen peroxide also damage the sealant so that we'll have to re-varnish the whole floor? I'm just worried that the spot will still be noticeable if its colour changes.
By Linda AH
I foster dogs and one peed on my hardwood floors. I have used some cleaners and it still doesn't come out.
Any ideas short of sanding and refinishing the floor?
|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...
|By Mary from Denver|
|they said PEROXIDE, not bleach. Peroxide bleaches your hair, but it's not CHLORINE bleach, which gets your whites clean.|

|I gave hydrogen peroxide a try and to my shock it works! It is slow going and I am not finished yet but so far have had good results. :-)|
|Tried the hydrogen peroxide. It works! I used it on oak cabinets that the little guy got into and peed in.|
Can anyone help me with cat urine stains and smell on hardwood floors? I plan on refinishing them so anything will help.
Ginny from Quincy, MA
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)
Try the urine remover here - http://www.furnitureclinic.co.uk/Urine_Remover.htm
It will remove any staining and kill the odor (07/13/2006)
Can't you use a bleach/water solution to clean/sterilize old hardwood floors, before going over them with a dust mop and liquid gold? (07/14/2006)
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.
How can I get pet urine stains up from a hardwood floor?
Betty Lou from Arkansas
I've been trying soaking rags in the hydrogen peroxide and leaving them on the stains. They don't smell very good, but when I change them they do have brownish stains on them. I'm hoping that's the urine coming out of the wood. I only see slight improvement after doing this for several days and am wondering how long this process should take and when I should just give up and call in the pros. How much of an improvement is it realistic for me to hope for? These stains are a couple of weeks old (that's how long we've had our puppy) but in some areas they are pretty dark. Thanks everybody! (08/25/2007)
Follow-up to my earlier post; my floors are looking MUCH better! The spots are still visible but nowhere near as bad as before. There are no more black spots, they're just a bit darker than the rest of the wood. I'm hoping that with more soaking they'll lighten up even more. At least if I re-do the floors some day they should turn out okay. So if you're trying the hydrogen peroxide, don't give up too soon. Good luck! (08/31/2007)
I have a large blackened area that I started using peroxide on yesterday. After about 36 hours, I can see a noticeable improvement. I have been using rags soaked in peroxide, covered by plastic wrap, and have used weights to hold them in place. (10/01/2007)
Check out this link for great information on how to bleach stains on wood floors. http://www.oldhouseweb.com/stories/Detailed/214.shtml
We found the solution here to a problem area on an oak floor with a very large blackened area due to an older dogs incontinence.(b)(/b)
We did have to try most of the suggested treatments, til we found the one that worked for us. We did not want to stain the oak after sanding, just seal it with clear sealer. The treatment lifted the stain after multiple applications, and it looks beautiful.
We found the Oxalic Acid mixture worked the best. (10/14/2007)
By Peke Mamma
We just moved into an old house and the guy before us had a few indoor dogs and cats. When we pulled up the old nasty carpet, we found old nasty, worn out wood floors. He lived there for 12 years and just about every corner and surface of floor next to a wall is just saturated and stained from all those years of the animals peeing on the carpet and it soaking into the wood! Are these floors salvageable? Will peroxide work? It's almost the entire house that's affected. Any suggestions?
Editor's Note: If you are going to re carpet, get some shellac like Bin or Kilz and paint the floors where it is discolored. It will seal in the smells. If you are trying to use the floors, you could try peroxide and see if it works to bring the floors somewhere back to the normal color. (10/31/2007)
Peroxide may do more damage than good for your floor and may actually bleach the area. I suggest that you use ammonia to strip the area and then follow up with Murphy's oil soap. If the smell is still there, then put a dish of vinegar in the room and this should absorb the smell in the room. (11/19/2007)
I am so glad I found this website. I went out today and bought some peroxide and a spray bottle. I took up my carpets two days ago and found several pet stains left from the previous owners dog as well as my own, peeing on the same spot. The peroxide is doing the trick. Instead of covering it with a rag and plastic, I decided to cover it with Baking Soda. The baking soda does two things, it absorbs the moisture and stain and also gets rid of the odor. I have repeated this method about 4 times, first I spray the spot with peroxide and let it sit for about ten minutes, then cover the dampened area with a layer of baking soda. I wait another ten minutes then go back and gently scrape up the now almost solid baking soda. (09/07/2008)
Thanks for all the feedback that everyone has posted. Will try out the ideas here very soon.
There is no way to get the stains out. Sand your floors and stain it to a dark stain, and no one will be able to tell. Remember, a DARK STAIN. I re-do homes and that always works for me and looks really great. Good luck. (10/10/2008)
How do I remove pet urine stains from my hardwood floor?
Lisa from Rockford
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)
How do I get black urine spots from my dogs out of my hardwood floor?
I'm sorry, you'll have to sand them. But you could try "OUT!". It has an enzyme that "eats" the urine. But I'm pretty sure the dark stain is permanent. (07/14/2009)
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)
How do I get black urine stains, from my dog, off a hardwood floor?
By Olwynnel from Alna, ME
I seriously doubt it's entirely redeemable, but for starters, I'd go to a pet or janitorial supply place and get the enzyme odor stuff. It dissolves organic residues, so it might remove some of the stain. I'd apply once, leave and observe for a few days. If it helps, see how far it will take the process of removing the stain.
After a few weeks, if the stain is better, try a q-tip with bleach water in a tiny spot. Sometimes bleach water removes stains from wood. Then wood needs to be sanded as the grain will be raised. Then it will need to be re-stained to match the rest of floor and varnished. That's if it is an old floor.
If it's a new floor, maybe just buy some replacement pieces, skip all of the above, and replace the damaged pieces. (08/25/2009)

How can I remove the dark stain left by pet urine on my hardwood floor?
By Margaret from Niceville, FL
I wonder if real mayonnaise would take it out? I have never tried it for removing rings off of tables, so I am not sure if it even works. (04/04/2010)
We had two week old cat urine stains that we finally found on the 90 year old top nailed white oak floor. The same two locations were peed on multiple times, so they were both dark and deep stains. There are lots of things you can try. I read a lot online, and just started trying things. Always test what you try in an obscure location, in case you do not like the result.
First I used Petastic odor and stain remover for cat urine, which is the same formula as Nature's Miracle. After two applications, which were each left there for an hour, there was still a dark stain and odor. After much online research, I decided to try 3 percent hydrogen peroxide, which I put directly on the floor. This lightened it some. I then put on hydrogen peroxide mixed with baking soda, in no particular proportion. This created small oxidation bubbles, and I could see and smell urine being lifted to the surface. I rinsed this clean, and used Petastic again. I rinsed that clean, and let it dry overnight. This morning, the stain is substantially lighter, and looks a little "bleached". It smells a little of urine, and a little of Petastic when I put my nose right next to the stains.
The floor will definitely change quite a bit in the hours after applying peroxide, so you may want to be more patient than me and just put one application on per day.
I'm enclosing a photo of the current state of one stain, prior to any further application or sanding. This was almost black when I started.
I may put some peroxide on the places that are still a little dark, and next we will sand it and put some sealer on it. In a few years, the floors throughout the house will be refinished, so it will be fully addressed then. Hopefully we won't have to replace floor boards, but that is a possibility.
This happened because I was distracted for a week or two and did not provide an optimum litter box experience for my two cats. Always keep the litter box clean! (06/03/2010)
