I went through the same thing. Its ugly. The cat urine in my house was at least 5 yrs old when I bought the house and it stillmade me gag. It gets in the cells of the wood.

One thing I found to help was vinager…..then put some kitty litter on top of the mess. When dried, vacumn up. This helped quite a bit. You might give this a try before moving on to the more expensive stuff.

When we sanded, the smell came back and the stain remained (I tried wood bleach to no avail). I ended up replacing many of the worst boards and then sealing them. Now, you would never know.

So, there is hope :-)

I came across a product a few years ago which is a god-send at getting urine smells out of carpet. I’m not sure if it would work for wooden floors but might be worth investigating. It’s called Nature’s Miracle and you can buy it online from various US pet stores. Besides the fact that it works 10 times better than anything else I’ve ever tried, as the name suggests it’s organic. We buy big bottles now which last us several years … we buy in bulk as we have to get it mailed from the US as we’ve not been able to find a stockist in the UK. The idea of shipping cleaning products internationally sounds ridiculous but it really does work that much better (and has saved us at least one carpet replacement so more than paid for itself).

Just from reading the links you posted the first one looks and sounds the best. Sorry I don’t have any experience with cat pee on hardwood floors. My aunt, who has cats and carpet sometimes has problems with the stink of cat spray (even after washing it’s hard to get the smell out) so she puts down crushed mothballs or mothball crystals. The smell isn’t great, but it does kill the stench of the cat spray. If it is something that sweats out in the heat maybe you could use some sort of oil dry granules that would absorb what comes out? Maybe even try some plain clay-based cat litter and then sweep it up.

Mindy While you are waiting to find out the ideal product try some vinegar and water. It might help. Some baking soda in a bowl in the corners also might help absorb the odor. Of course your puppys might get into it but at least it shouldn’t hurt them. At the hardware store you can also buy “Fast-One Drop” deodorizer. Good luck

Mindy,
My dad swears by Nature’s Miracle. I don’t know if they sell it in bulk, but it the only thing I’ve heard of that works.
Do you have a dehumidifier to try to avoid the moisture oozing out of the wood? I’ve been meaning to buy one myself. You have no idea how much the smells in basements and such are caused by moisture. My dad’s basement is 100% different since he bought one.

You guys rule :)

I had a bottle of Nature’s Miracle on hand, since one of our dogs still pees in the house from time to time. I know a lot of people that swear by it.

After reading some things on the internet, my plan of action today was as follows:

I put Nature’s Mircale in a spray bottle and sprayed it lightly on the areas that were sweating. Then I took some Arm & Hammer Baking Soda Pet Odor Eliminator powder and sprinkled it over the areas to soak up the moisture & the smell. This was something I read about online, and figure it can’t hurt. It does seem to be sopping up the moisture, and it has certainly taken care of the odor. Tomorrow, I’ll vacuum it up and reapply if necessary.

It isn’t pretty, but as long as the dogs aren’t eating it and the smell is gone I don’t care what it looks like! If nothing else, it’s making me FEEL less gross, because it looks like it’s taking some of the pee away.

StuccoHouse - glad to know there’s hope! We already knew we’d be replacing quite a few boards, as they are badly stained. Wish we were closer to the refinishing job - we’re waiting till after the basement jacking is finished. Which won’t start until the kitchen addition looks good from the outside, the chimney is fixed… the list goes on and on and on!

p.s. - Gram, I bought some vinegar at the store today before reading your comment because of that note you left me. Vinegar has got to be the most versatile thing ever!

I read an article stating that all cleaning products were really just ammonia, bleach, or vinegar with some color and fragrances added. Those three substances should clean nearly everything in your house, apparently. So maybe we should all stop buying a different (expensive) cleaning product for every surface in the house!

I’m going to try the vinegar tomorrow ;)

Whatever you do, don’t try to clean with ammonia. Ammonia is great for a lot of things, but will actually fix or bind the uric acid particles to your floor. The enzymatic cleaners like Nature’s Miracle work great on fresher stains, but I’m not sure how well they will do to really minimize very old odors and staining.

I realize I’m long past helping now, but thought this may work if you’re still looking for ideas….we use “Pine Fresh” litter for our cat. It’s little pine pellets that turn into sawdust when they’re hit with the ammonia of cat urine. They completely neutralize the smell, and the sawdust is compostible (sp?). So you might try sprinkling it on the bad areas to absorb all the excess liquid.
Just an idea. I have not tested it as I have not been graced with this particular problem, but it might be worth a shot if it happens again.

Another potent cat stink remover (not organic, but wicked effective) is called “Anti Icky Poo.” Yes you read that right. http://www.antiickypoo.com/
My beloved (almost beheaded) cat peed right in the middle of my bed - no washing that out, it was in the springs and i didn’t want to rust them out. This stuff has some kind of enzyme beasties that eat nasty odors. Which was handy, because while i had it out on the front porch to dry, would you believe a neighbor’s dog came along and peed on it, too? And, although i no longer sleep on it, it’s amazingly still able to be used as a covered couch with no smell. God bless geentic engineering for odor eating enzymes!!! (Just leave my tomatoes alone).

Haha, Oh, Faster Pussycat - that’s terrible but hilarious!

Thanks for the link!

Well its been 5 months and I’ll bet you still have the odor. too bad you didn’t try your second choice. It really works on just the problem you have.

Did the smell come back? We are in a similar situation, but with dog urine.
The hardwood floors were refinished but the urine sweats through the hardwood.
Did anything finally work for you?
Help……….:(

We are in the same predicament as you! We have gone through 4 bottles of Urine-Off with no luck yet. Did any of the remedies work for you? Please respond!!! :)

Hi! My husband and I bought a house in June which needs many renovations and we LOVE your site! Very interesting and so useful. We have a lot of the same problems/repairs as you. We are currently dealing with the cat urine problem… Apparently the previous owner’s cat(s) decided to use one of the bedrooms as its personal litter box. The rest of the house is fine, but that one room is nasty. The wood doesn’t seem to be seeping any moisture, but sure does smell more in the heat and humidity. How did the Nature’s Miracle work for you?? Please respond! :)

I bought a house that was used as a rental…..the tenants had 5 BIG dogs that, after they were evicted, were allowed to stay in the house , only being fed & given water maybe twice a week….when they finally left & took their poor dogs , I had the biggest mess I’ve ever seen on my hands…..I pulled up all the carpets , but the urine had gotten into the pine plank subfloor……I tried everything to get it out until I found a local company that does restoration work that guaranteed me they could get the smell out , never to return again ( unless I let a dog pee in there again )……they used the same method on my house that they use when cleaning up after a human corpse had been in a house for a long time………they put their guarantee in writing. & I was told nobody has ever in 20 yrs. called & said the smell came back……….they’ve done the work for $480 + tax……..

i need to know what is the best thing to get human urine out of wood floors and it is the floor of the house not any overlay wood floor. I afriad to carpet it and the smell still comes thru. It is getting hot and i don’t know how old the smell is. I heard alot about the vinegar please let me know if this works or just a quick fix Thank Patty

Our son urinated on our steps trying to make it to the bathroom. I thought I cleaned it good until the hot weather came, and it stinks horrible. We use those stairs often, and I’m wondering what you think the best thing might work since it was on the stairs. Does peroxide damage your hard wood floors? Do I need to let it sit for a short time or at least 15 min?

Hi

i have a rental unit and the tenant is using the deck as dog pen - the dog does his business on the wood decking. I am worried that this is going to cause damage and long term odor problems. I have never seen my tenant mop or attempt to clean the surface of the deck - though he does on occaison pick up the poo - Is this doing damage to the wood? what should i have him do to fix any damage? is there something he could put down on the surface that would protect it? he does this due to his long hours at work.

thanks

I have had two different homes with exterior wood treated decks and my dogs used them for their bathrooms and neither have ever smelled. I used to rinse the urine off with hot water right after she did it. I am still in the house and I just went out back and put my face to the deck and there is no smell. I have put sealer on it last year but never noticed any smell before I did that so I would not worry about it so much. IT would be nice if they rinsed the deck off once in a while.

I need to know if it is possible to repair bad floor joists without having to take up the subfloor. We have some termite-damaged joists that need to be replaced and the contractor who looked at it said some of the subfloor was also involved and they could only fix it by taking up the floors and redoing the underneath.

Anyone had any experience with this? Our house is over 100 years old

I need something to kill the smell of oily nasty water that leaked out of my baseboard radiator onto my wood floor over about a week. The stains/smell are over a year old but it smells like it’s freshly spilled.

Most of the floorboards have swollen up. I used a wood floor cleaner and put fans on it to dry it for about 2 days straight. No effect on stains or smell.

The heat definitely makes it worse.

Replacing the floor is not an option. Any ideas?

I know vinegar and baking soda might work separately - would they work together or would that just be a bad science experiment?

Thanks,
B.

Martha,

We repaired some of our joists from the basement, but I assume you mean joists you don’t have access to? If so, then I don’t know of any better option than pulling up floorboards.

B,

I would suggest trying baking soda by itself - this seemed to pull remaining moisture out of our floors.

Hmmmm,

I keep reading that Nature’s Miracle is just that; a miracle. But so far, I’m having a tough time agreeing with it. My 2 Chi puppies have been peeing probably for several months in one corner of the room on the carpet. Unfortunately we didn’t notice it until recently when we started to smell it. Yuk! We tried Nature’s Miracle on it and it didn’t seem to help. Then we decided to pull up the carpet in that corner and soak the back of it with Natures Miracle. Well, it’s been drying for several days now and it still smells like pee. I might add that after the Nature’s Miracle dried on both sides of the carpet, we deep cleaned it as well with our carpet cleaner using a strong pet formula shampoo. Still smells. Are we doing something wrong? We’ve about decided that the only way to get the smell out is to replace the carpet. Can someone save us some $$$ please?

Thanks

Hi everyone…

One of my guinea pigs recently escaped and he urinated on our hardwood floors. There’s now a big black stain on the floor and I need to know how to get it out. It doesn’t smell, it’s just really ugly. This is a rental home for us so replacing the floor boards isn’t really an option for us…willing to try just about anything else.

Hi all. Just bought a house and dealing with a carpeting and urine contamination problem.

Have been researching for a few days: as far as home remedies go, I would not recommend a vinegar solution — too much controversy surrounding it.

The problem is uric acid and bacteria — this is the source of the odor. Google for more information. One remedy you may try is an old one that Mythbusters tested for skunk odor: it’s a mixture of hydrogen peroxide, baking soda, and soap. Some folks have reported success with this, but you should test for colorfastness — again, Google for more information.

Also, in extreme cases, I have read that some people have had good results by shocking the area with an ozone generator — this is what a lot of professional companies use for odor cleanup.

I am still researching and testing, so I will try and report back with my results.

Good luck…
