The short answer

Remove Water and Wet Materials

First, get rid of any standing water using a wet vacuum or pump. Remove soaked rugs, carpet, padding, and any furniture that absorbed water. Pet urine soaks deep into these materials, so leaving them in place spreads the odor and makes drying harder.

If the floodwater was dirty or contained sewage, treat everything as contaminated. Wear gloves and boots, and bag wet items for disposal. For porous items that cannot be cleaned thoroughly, throwing them away is often the safest choice. This step prevents the urine from seeping further into the subfloor.

Clean with an Enzyme Cleaner

Enzyme cleaners break down the proteins in pet urine and are the most effective option for removing odor. Apply the cleaner generously to the affected area, following the product instructions. Let it sit for the recommended time so the enzymes can work before you blot or rinse.

Avoid using bleach or ammonia, which can react with urine and make the smell worse or create harmful fumes. For hard surfaces like concrete, scrub the area with a stiff brush after applying the enzyme. Rinse with clean water and extract the moisture using a wet vacuum.

  • Use an enzyme cleaner labeled for pet urine
  • Let the cleaner sit for the time stated on the label
  • Scrub hard surfaces with a brush
  • Rinse with clean water
  • Extract all moisture with a wet vacuum
  • Repeat if the odor remains

Dry the Area Thoroughly

Drying is critical because lingering moisture lets odor-causing bacteria grow. Open windows, run fans, and use a dehumidifier to pull moisture from the air and surfaces. In a humid climate like Columbus, drying can take longer, so be patient and keep the air moving.

Check for hidden moisture in walls and subflooring using a moisture meter if you have one. If the area stays damp after a few days, the water may have soaked into materials that need removal. Structural drying and dehumidification services can help if the space is large or hard to dry on your own.

Decide What Needs Replacement

If the odor persists after cleaning and drying, the urine may have reached the subfloor or wall framing. In that case, you may need to remove and replace sections of drywall, flooring, or padding. Cutting away damaged material is often the only way to fully eliminate the smell.

Before cutting into walls or floors, check for electrical wires and plumbing. If the floodwater was contaminated, consider replacing porous materials rather than trying to salvage them. For extensive damage, local water damage pros can assess what can be saved and what should be removed.

When to Call in the Pros

Large flooded areas with pet urine can be overwhelming, especially if the water sat for a while. The pros have industrial extraction equipment and drying systems that can reach deep into materials. They can also identify hidden moisture pockets that cause odor to return.

If you live in Columbus, you can search for the pros who handle flood cleanup. They can help with extraction, drying, and removal of affected materials. Water damage inspection and moisture mapping services can pinpoint the extent of the problem before you decide on repairs.

Frequently asked questions

Can I use baking soda to remove pet urine odor?

Baking soda can help absorb some odor, but it does not break down the urine proteins. For a lasting fix, use an enzyme cleaner first, then sprinkle baking soda after the area is dry. Vacuum it up later. It serves as a final touch, not a substitute.

Will the odor go away on its own after the area dries?

Drying can reduce the smell, but it rarely eliminates it. Pet urine leaves salts and bacteria that react with humidity and return as odor. You need to clean with an enzyme product and possibly remove soaked materials to fully get rid of the smell.

What if the floodwater was from a broken pipe, not a river?

The process is similar, but the water may be cleaner. Still, pet urine in the area needs the same enzyme treatment. Check if the pipe water was safe to handle. If it was contaminated, treat it like any floodwater and take the same precautions.
