10-4 ❗️ Message received ! Go directly to sanding and skip that unnecessary fore play with chemicals !

I’m working on removing the active smells of my senior dog. I’ll take on the cosmetics after he passes. As long as my house doesn’t smell like a kennel, I think we should focus on keeping him comfortable moreso than how the floor looks.

Good job! With dark stains like that we normally just remove the boards then sand them flush. I was amazed you got that out

Thank you. Getting ready to try this on some pet stains. Thank you for the detailed before and after photos.

Just a side note, H2O2 has a pretty short shelf life, maybe good for a few months once opened.

Wiping it doesn't do anything. Soaking 3 layers of paper towels for several hours is key. I mean soaking wet. You need to look for the urine soaking up into to paper. Once you see quite a bit of yellow brown, change the paper, add more hydrogen peroxide. Keep doing this until it barely bleeds out. That's literally the urine leaving the wood. The paper towels are like the vehicle to which it can leave.

try using Bar Keepers cleaner to scrub it. It has oxilic acid in it that is the basis for bleaching wood.

Based on my internet searches, the H2O2 works with multiple long periods of soaking, and long periods of drying. The short spurts of chemicals without the patience do not seem to work. Obviously the chemicals work better on an unfinished floor, as the purpose of varnish, etc is to protect from water penetration. It just slows the work of something like peroxide. I am going to say peroxide over oxalic acid, as I use peroxide to remove carpet pet stains and odors routinely. I do not pay for the expensive spray products, and just have 3% H2O2 in a sprayer available. It takes out any colored stain. Peroxide is oxygen bleach, ie “OxyClean” in a bottle that is super cheap-99 cents per liter on sale. Forget the branded stuff. We have white carpets that are 21 years old and have had every kind of stain from blood to red wine, liquid poop, chocolate, red soda, and 4 dogs worth of piss stains. Still beautifully white-until the next accident, which is frequent. Just pretreat and use the carpet cleaner. My husband is super fussy, and he does not even notice any odor.

God damn dogs! Grats on removing the stain and this helpful video. I'm about to tackle the same job, but my stains are darker.

Two solutions. Oxalic acid or hydrogen peroxide at 30%. Use a pet pee pad to reduce evaporation.

Thanks for the video research 👌🏼

you have to let it sit until it completely dries (not just 20 minutes), and it can take many treatments of doing this.

Whoa, there is hope for my floor!

You have to do it several times a day for weeks but it does help...eventually

nice that sanding worked. I wonder if oxalic acid would have worked better than peroxide if sanding wasn't an option.

Thanks for the video! We are going to tackle a similar spot (with a full floor refinish, also), and I was worried this stain wouldn't come up. Of course it's right in the walk-way entry, not in the middle of the room where it could be covered with a rug if need-be. We ripped up OLD carpet (from the early 80's?) and found these same spots. Any change of a before and after shot of your floor finished?

Did you sand the entire floor or just the damaged spot? If it’s the later, did the finish match with the old?

i seeit does nothing for stains. how about odor ???

what sander did u use? I'm about to take the same kind of job

Throw rug

So are you just saying to use a 24 grit on the sander?

Just replaced the boards man lol.

Ahha so just borrow a sander then. Oky doky lol

Ahhhhhhhhh stop the madness!!!
