What you should know about cleaning subfloors?
Pet odor is one of the commonest odors that happen to subfloors and the best bet is to use an enzymatic pet cleaner to achieve the cleaning job. These pet cleaners are composed of enzymes that convert organic waste into carbon dioxide and water. They are also effective in removing oil, grease, food, and wine stains. Be sure to sweep and vacuum the floor completely before applying any of the cleaners.
Select an enzymatic cleaner that is specifically for the kind of odors and stains on your subfloor. However, you may need to use more than one of those products. Go for a cleaning solution that contains protease if your subfloor has urine, wine, and bloodstains. Cleaning solution that contains lipase is good for removing oil and grease.
Cleaners that are composed of amylase work better for starch-based stains, sugar, and egg stains. It is important to read the instructions written on the product label or manual guide. After applying your chosen cleaning solution to the subfloor, allow it to sit on the floor for up to a day so it can work effectively as desired. Rinse and dry after.
Other ways to clean subfloor
You may decide not to use an enzymatic cleaner but a homemade cleaning solution. Combine ¼ cup of dish soap, 1/3 cup of white vinegar, and 1 cup of warm water in a spray bottle. Shake the bottle very well to get it properly mixed, then spray it on the subfloor. Use a neat cloth or towel to wipe it off. Inspect the subfloor if what you just did has an effect on it. If it does, mix a large amount of the cleaning solution you just prepared and wash the subfloor with a sponge.
You can also combine a part of bleach or hydrogen peroxide with warm water. Apply this mixture to clean the subfloor. Use a mop over the subfloor surface and use a clean towel to dry it afterward. Allow it to dry completely. Make sure to wear protective gloves, a mask, and goggles when using any of the cleaners.

How to treat pet odors from subfloor?
If you have pets like dogs and cats in your home, escaping pet odors from your subfloor is almost impossible. When pet urine dries, it turns to crystals and releases a bad odor. Even after replacing the old carpet and rug pad, you may still end up with such stench because it would have soaked inside the wooden subfloor.
You may not really need to replace the wooden subfloor, just lift off the new carpet to locate where the stench is coming from. In some cases, it is not possible to eradicate the odors from the subfloor. So, you will need to cut out the affected area and replace it, then treat the remaining part of the subfloor with a cleaner specially meant for pet urine before replacing the carpet.
In a case where you want to deal with cat urine, effectively cleaning it relies on some factors like where it is located, how long it has been there, and the kind of surface it was deposited on. We are dealing with wooden subfloor surfaces here. The recommended cleaners you can go for should contain enzymes that can break down and neutralize the urine odor.
Firstly, use a wad of paper towels and press firmly into the affected area to soak up as much liquid as possible. There are various commercial cleaners for pet odors in nearby hardware stores. Make sure to read the instructions in the product manual guide. You can as well use several homemade cleaners as an alternative.
- Hydrogen peroxide: Spray a generous amount of hydrogen peroxide on the affected spot and allow it to sit for about 10 to 15 minutes depending on how large the spot is. Then, dry it clean with a clean towel.
- To prepare a more concentrated solution, mix 3 percent of hydrogen peroxide with a small amount of dish soap and little baking soda. Spray this mixture on the affected area and allow it to sit for a few minutes. Then, use a clean cloth or towel to blot dry.
- White vinegar: Mix warm water with about 25 to 30 percent of white vinegar. Spray the mixture on the spot and let it sit for a few minutes before you dry.
Caution: Always test these homemade solutions on a piece of carpet or areas out of sight to confirm they won’t cause damage to your subfloor. Ensure to avoid products that have ammonia content.
Eliminating odors from concrete
Concrete is porous and it soaks in liquid which can lead to smell whether it is subfloor or an outdoor floor in a basement, garage, or kitchen. Enzymatic cleaners are effective at neutralizing odors on concrete. It is wise to choose a cleaner that has trisodium phosphate content. Pour 1 gallon of warm water into a bucket and mix with the cleaner.
Apply the cleaning solution to the floor and allow it to absorb for about 10 minutes. Make use of a short-bristled nylon deck brush to scrub it in. Then, rinse the floor with warm water 2 to 3 times. You may need to vacuum the subfloor to get rid of excess water.
