How To Get Dry Dog Urine Off My Walls

Dog urine, a ubiquitous aroma in most households, is bad for your interior health. While it may not harm you, that doesn’t mean you should ignore its presence.

Your dog can spread many potentially harmful bacteria and viruses through his bodily fluids and is responsible for getting your carpets or furniture wet.

When your dog urinates on the walls, it leaves a powdery film of dried urine.

First, break down that film by pouring warm water over it and then scrub it with detergent. This will loosen the uric acid salts from the urine and allow them to dissolve in your detergent’s surfactant, which you can rinse away after scrubbing.

Another method you might use is mixing some of your detergents with water, then adding some vinegar and squirt it into the affected area.

The vinegar will create bubbles that will dissolve the uric esters from the dry food and make them easier to dissolve in your detergent. Repeat this until you achieve a good result, then rinse with clean water.

You can also apply a pet-safe enzyme cleaner to the affected areas. These cleaners boast enzymes that break down the uric esters and soften them.

You can use a damp sponge to wipe off the liquid cleaner, or if you use a sponge, it is best to do this in a wet area.

However, you should not let the solution dry on the walls, which can cause the uric esters to harden, causing the walls to discolor and stain.

Is Dried Dog Urine Harmful?

Yes! Here are some reasons why dried dog urine is harmful

1. It Causes Respiratory Problems

Dried dog urine creates a dangerous feeding environment for microbes and molds. When left uncleaned, the molds accumulate and cause respiratory problems, especially for children and the elderly.

2. Food Contamination

When you expose dried dog urine to the air, it begins to polymerize and will begin to form a hard coating.

The bacteria in the urine are also released when drying out, which can cause food contamination, especially if the food is for human consumption.

This may lead to issues such as diarrhoea, nausea, and vomiting.

3. A Breeding Ground for Insects

The dried dog urine left in areas like the basement and the attic provide a perfect breeding ground for ants, roaches, spiders, and even rats.

The bodies of these insects also create more harm as they decompose. They can also cause allergies in people who are sensitive to insect bites.

4. Bad Odor

When you leave the dried dog urine uncleaned, it begins to decompose, and the odor it emits is very unpleasant. The smell may cause discomfort and disturbance to the people in the house.

5. Discolorations and stains

The dried dog urine’s color varies depending on when you left it uncleaned. When you don’t clean the urine, it begins to form a dark greenish or brownish stain, especially on clothing and carpets.

The urine may also form a yellowish stain on certain porous materials leading to damage.

Does Rubbing Alcohol Neutralize Dog Urine?

Yes! Rubbing alcohol can help to neutralize the odor of dog urine.


One of the main advantages of using rubbing alcohol to clean up dog urine is that it will help neutralize the odor.

Dog urine contains smelly sulfur-containing compounds that wood and fabric absorb.

But, when you apply alcohol to dog urine stains, it releases these odorous compounds from surfaces, making them easier to remove.

Rubbing alcohol also helps remove the stain by causing the urine to evaporate.

When you clean dog urine with rubbing alcohol, it dissolves in the water, causing the urine to run deep into the surface of wood and fabric.

Once this happens, any residual stain will weather away quickly with just a bit of sunlight.

Rubbing Alcohol Disadvantages

One problem with rubbing alcohol is that it may not dissolve non-water-soluble materials like protein and minerals left behind in dog urine.

When this happens, you may end up with a yellowish residue you cannot remove until you use an enzyme cleaning product.

Rubbing alcohol can also cause staining if it comes into contact with freshly painted surfaces. This is because rubbing alcohol is extremely drying and can cause paint to flake off.

To avoid staining any freshly painted walls or floors, always test rubbing alcohol on an inconspicuous area first to make sure it won’t cause damage.

How to Get Dog Urine Off Painted Walls

To remove dog urine from painted walls, you can try the following steps:

  1. Blot up as much urine as possible with a clean, dry cloth.
  2. Mix some water and white vinegar and put it in a spray bottle. Spray the mixture into the area of interest and let it sit for some time.
  3. Scrub the area with a scrubby object, being sure to reach all of the paint.
  4. Put a pinch of baking soda on a damp rag and rub the smell from the wall. If necessary, repeat this step several times.
  5. After you believe it has dried, rinse the area with water and dry it using a clean cloth until no moisture appears in the pores of the wall’s surface.
  6. Once dry, use a fine wire putty knife to scrape away the affected paint area. The dog urine should wipe away reasonably easily.
  7. Once you remove the urine and cure the wall, you may want to reapply paint, but be careful to use up as much as possible of any leftover product. 

If you opt for this method, ensure that you only clean one wall at a time so that no cross-contamination occurs.

Remember: If the smell returns, you should try another method. Also, clean your pet after accidents and keep them from marking in the same area again.

What Is the Fastest Way to Remove Urine Stains?

Vinegar And WaterMix equal parts white vinegar and water and sprinkle some baking soda on top of the vinegar-water solution. 
Hydrogen PeroxideApply to the stain, leave to dry in 5-10 minutes, and then scrub with an old toothbrush or similar item.

Use gloves when using this method, and avoid contact with the eyes, skin, and clothing you care about.
Hydrogen Peroxide and VinegarMix equal parts of hydrogen peroxide and white vinegar and apply to the stain, leave to dry in 5-10 minutes, and then scrub with an old toothbrush or similar item.
Tide DetergentApply directly to the stained material (paper towel) first, then scrub with an old toothbrush or similar item.
Baking SodaIf you want to keep the chemical smell of baking soda for a short time, then add it to the mix and spray the solution onto the spot, let it dry, and then scrub with an old toothbrush.

How Do You Clean Painted Walls Without Removing Paint?

You can use a solution of white vinegar and water to clean dog-dried urine on painted walls without removing the paint.

Mix equivalent amounts of white vinegar and water in a spray bottle. Spray the mixture on the affected wall and let it sit for a while.

Then, use a clean cloth or sponge to wipe the area clean. Repeat if necessary. Avoid harsh chemicals or abrasive scrubbers, as they can leave scratches on the walls.

When the problem is minor, try using a water-dampened rag or towel to wipe the stain. If there are a lot of cleanups, try using a plastic scrubby with warm water.

Dab at the area until it’s clean. To remove the remaining odor, spray baking soda on the dog stain. Let it sit for several minutes. Afterwards, vacuum it away.

After you clean the stain, use an all-purpose cleaner to give the area a good wipe-down. Disinfectant wipes are great for this purpose.

Avoid cleaning products containing ammonia, as they can cause some dogs to urinate in the same spot again.

To prevent your dog from returning to the same spot to urinate, you should also remove the odor causing it. You can do this with an enzymatic cleaner or a homemade doggie odor spray.

Does Toothpaste Remove Wall Paint?

No!Toothpaste does not remove wall paint. However, I do not recommend using it to remove dog urine on painted walls.

This is because toothpaste does not have the ingredients to remove paint. In addition, toothpaste will leave a stain on anything it is applied to.

Here’s what you need to know:

Wall paint does not boast the same materials as regular paint. It contains a thickening agent, so it doesn’t spill or run as much. As toothpaste does not have a thickening agent, it cannot remove the wall’s paint.

Toluene and Xylene are chemicals found in paints that are especially effective in preventing stains removal with most cleaning products.

Toothpaste does not contain either of these special chemicals. Therefore, it is unlikely to remove the paint from your wall.

Toothpaste is only effective in removing stains when old-fashioned lead-based paints cause them.

If your dog urinates on a surface previously painted with lead-based paint, you can use toothpaste to remove the stain.

This is because the chemical composition in toothpaste is effective against lead-based paints.

Old Dog Urine on the Hard Wood Floors- What to Use

White VinegarMix a 50/50 solution of white vinegar and water in a spray bottle and Spray the mixture on the floor, let it sit for 5 minutes, scrub it off using a stiff brush.
Baking SodaSprinkle baking soda over the entire area of old dog urine on hardwood floors and wait an hour before sweeping it up.
Rinse as usual.
Vinegar And Baking Soda (Purchase A Pre-made Mixture)Add several drops of vinegar to the baking soda solution (15 minutes before using it in the mop).

This mixture will not produce suds, but the smell will go after scrubbing.
Salt And Baking SodaSprinkle salt on the entire area of old dog urine on hardwood floors for at least five minutes before moping it up and rinse as usual.

Clean Dog Urine Off Walls Using Hydrogen Peroxide

Hydrogen peroxide is powerful at killing bacteria and removing odors at once, and it’s a cheap, easy cleaner. So, when your dog urinates on the walls (again), follow these steps:

Spray hydrogen peroxide on all surfaces touched by the urine. Wipe up with a paper towel or cloth until clean.

If any odors are left behind, wipe again with peroxide or use a spray bottle of water and peroxide to eliminate them. Once the area is odor-free, apply water-based paint or gel to seal in the fresh smell.

It’s worth noting that peroxide is an irritant that can burn your dog’s paws and skin if he directly contacts it.

Wash your hand thoroughly after you’ve finished cleaning. Also, avoid letting your dog lick his paws after cleaning because the alcohol on his fur can sting his gums.

After using peroxide to clean the tricky spot, ensure that you get rid of the remaining product. The chemical can react with fresh paint and create an unsightly mess.

Be sure to do a test with the paint you plan on using first, and keep peroxide at least 12 inches away from all materials that aren’t porous.

Clean Dog Urine Off Walls Using Ammonia

To clean dog urine off walls using ammonia:

1.        Mix 1 cup of clear ammonia with 1 cup warm water in a spray bottle.

2.        Spray the mixture onto the area of interest.

3.        Let it sit for a few minutes.

4.        Wipe away the wall using a clean, damp cloth.

5.        Repeat these steps until you achieve a positive result.

Always use the ammonia solution in a well-ventilated area and wear gloves to protect your skin.

6.   If the stains persist, you can use a water solution or Hydrogen Peroxide to treat your dog stains. After the treatment, leave the wall for about 30 minutes, then scrub it off using a brush. 

7. Make sure the exercise is supervised for safety.

8. Check for any damage to your walls after cleaning.

9. Clean the area with a water solution after you are done to avoid any pet odors in the future.

Remember, you should clean the dog’s urine immediately after you see that the dog went on to urinate. If you don’t do so, then the odor will be maintained, and the results are going to be unfavorable
