We’ll provide expert tips and precautions to ensure you clean your hardwood floor with confidence.

Let’s Start.

Can Old Urine Stains Come Out?

The answer is, it depends on the severity of the damage. In some cases, old urine stains can be removed, while in others, the damage may be too severe to fix.

One factor that affects whether or not old urine stains can be removed is the type of damage.

If the urine has caused discoloration or dark spots on the wood, it may be possible to remove the stains with the right cleaning products and techniques.

Another factor that affects whether or not old urine stains can be removed is how long the stains have been there.

If the urine has been allowed to soak into the wood for an extended period of time, it may be more difficult to remove the stains.

However, even old urine stains can often be lightened or removed with the right products and techniques.

Method 3: Using Enzyme Cleaner

Meet the Enzyme Cleaner Avengers, specialized in dealing with organic marks and pet odors.

These heroes are perfect for fresh stains on hardwood floors, as they break down uric acid and other troublesome compounds.

They’re also great at preventing repeat offenses by wiping out all traces of the mess.

But, hold on! These avengers are no match for set-in urine stains.

You need them in action early on for best results.

Pet stain removers and hardwood floor cleaners like Bona or Rejuvenate are here to save the day.

They’re effective for surface-level stains and general floor cleaning.

However, they might not be the best choice for deeply absorbed urine stains.

Method 5: Using Oxalic Acid

Beware! Here comes the mighty oxalic acid, a.k.a. wood bleach!

This stuff is potent, so handle with care and wear your safety gear.

When other options fail, oxalic acid can work its sorcery on those deep urine stains.

Oh, and you might have to sand and stain afterward to restore your wood’s glorious look.

Method 6: Using Hydrogen Peroxide

Last but not least, our trusty ally – hydrogen peroxide! This DIY hero can clean those tough urine stains, but be prepared for a bit of a wait.

Method 7: Sand and Stain Strategy

Sometimes, my friend, we have to go all-in to win this battle.

Sanding and staining your floor might be the ultimate strategy to eradicate those black urine stains.

It’s not for the faint of heart, though. This one’s labor-intensive and could be quite costly.

How to Execute the Sand and Stain Strategy:

  1. First, watch some tutorial videos or consider hiring a professional, as this is a major operation.
  2. Get your hands on the necessary equipment and materials, which could set you back a couple of hundred bucks.
  3. Alternatively, you can hire a pro, but it’ll cost you more.
  4. Sand several layers to see if you can hide those pesky stains. If not, you’ll have to go all the way and redo the entire floor.
  5. If you do choose this route, consider using a dark-colored stain like espresso or charcoal. It might hide any remaining stains and give your floor a chic new look.

Method 8: Replace the Hardwood

  1. You’ll need a circular saw and a hammer/crowbar to cut out the stained sections.
  2. Have some spare floorboards ready for the battle. You’ll need them to replace the damaged pieces.
  3. Measure twice, cut once! Be precise and careful.
  4. Depending on your skills and preference, you can fix the new boards with adhesive or hide the nails under wood putty.

And don’t forget about those pesky odors! Use an enzyme cleaner on the subfloor to ensure there’s no trace of the enemy left to lure your pets back for more mess.
