Use Hydrogen Peroxide

If the urine has already been absorbed deep into the hardwood, you may have to soak the stain spots with hydrogen peroxide.

First, use a peroxide-soaked cloth to scrub the stain and let them dry. If the stains and odor persist, you can cover the stain with a paper towel or soft wipe saturated with peroxide.

Allow the towel to sit on the stained spots for a few hours, and repeatedly check every hour to see if the stain is removed. Once the stain is removed, you may notice mild discoloration on the floor, and as a result, it may require some refinishing.

Use Baking Soda

Baking soda can also be used to amp up the effects of the vinegar or peroxide cleaning process; it can be used to soak up any dampness or residue and deodorize as well.

Simply sprinkle a generous amount of baking soda over the area. Allow the baking soda to sit on the floor for about an hour before vacuuming. You can repeat the procedure if the floor is still damp.

Use Enzymatic Cleaner

Enzymatic cleaners are non-toxic and are very effective in breaking down urine stains and odors. Most enzyme cleaners are designed specifically for the elimination of pet odors.

Natural enzymes can be used to neutralize and thus eliminate the urine completely, but ensure to apply them accordingly to packaging instructions and apply it only on the stained spots.

You may need to repeat this process a couple of times before the stain and odor can be completely removed.

With a little elbow grease, you are bound to eliminate the stain but keep in mind that the stain and cleaning process may affect the wood; this may cause it to require a small sanding or touch-up.

Use Hand Scrapers

If the urine stains are small and fresh, you can remove them with a hand scraper. You would need to scrape the floor with the grain but avoid scraping the area too deeply; this is to prevent the formation of a nasty divot.

You can purchase hand scrapers at home improvement stores. Scraping your floor with a hand scraper may mark the floor, but you can use grit paper to remove the mark by hand sanding over the area.

Lastly, with a shop vac, clean the floor and seal the area with a surface finish.

Use Wood Bleach

You can also use wood bleach to remove pet urine stains. But this might only remove lighter urine stains from the hardwood floor.

The wood bleach would work the best if the affected area was sanded first. Sanding enables the bleach to penetrate the wood better and remove the black urine spot.

Ensure to wear gloves and properly ventilate the area by opening up a window before using this product. Also, make sure to apply it accordingly to packaging instructions.

Sand And Refinish The Area

Sanding and refinishing is a great way to get rid of the urine stain. Sanding can be used to remove every speck of stain on the floor, especially if the stain is not stubborn.

Make sure to match the newly sanded area with the surrounding area so they blend together and the newly sanded area does not stand out on its own.

Keep in mind that sanding may eliminate the stain but not the smell, so you may need to opt for another odor elimination method.
