How to Clean & Remove Urine or Pet Odor from a Mattress in 2023? – Step-by-Step Guide

Step 1: Act Quickly

When dealing with urine or pet odor on a mattress, it’s crucial to act as soon as possible. The longer the urine sits on the mattress, the more difficult it becomes to remove the odor. Prompt action can prevent the odor from setting in and make the cleaning process easier.

Step 2: Remove Bedding and Soak up Excess Moisture

Start by removing all bedding, including sheets, blankets, and mattress protectors. Place them in the washing machine for cleaning. Next, use clean towels or rags to blot up as much excess moisture as possible from the affected area of the mattress. Avoid rubbing the stain, as this can push the urine deeper into the fabric.

Step 3: Sprinkle Baking Soda

Baking soda is a natural deodorizer and can help absorb odors from the mattress. Generously sprinkle baking soda over the entire surface of the mattress, paying extra attention to the areas affected by urine or pet odor. Let the baking soda sit for at least 8 hours or overnight to allow it to absorb the odors.

Step 4: Vacuum the Baking Soda

After the baking soda has had time to work its magic, use a vacuum cleaner with an upholstery attachment to thoroughly vacuum the mattress. This will help remove the baking soda along with any trapped odors. Vacuuming also helps freshen up the mattress and restore its cleanliness.

Step 5: Treat Stains and Odor

To tackle any remaining stains and odor, you can create a homemade cleaning solution using white vinegar, hydrogen peroxide, and liquid dish soap. In a spray bottle, mix equal parts white vinegar and hydrogen peroxide, then add a few drops of liquid dish soap. Shake the bottle gently to mix the ingredients.

Step 6: Test the Cleaning Solution

Before applying the cleaning solution to the entire mattress, it’s important to test it on a small, inconspicuous area to ensure it doesn’t cause any discoloration or damage. Apply a small amount of the solution to the test area and blot it with a clean towel. If there are no adverse effects, proceed to the next step.

Step 7: Apply the Cleaning Solution

Spray the homemade cleaning solution onto the affected areas of the mattress, focusing on the urine or pet odor stains. Be careful not to oversaturate the mattress, as excessive moisture can promote mold and mildew growth. Gently blot the solution with a clean towel or rag, working from the outside of the stain toward the center.

Step 8: Air Dry the Mattress

After treating the stains and odor, allow the mattress to air dry completely. Open windows or use a fan to promote air circulation in the room. It’s important to ensure the mattress is thoroughly dry before covering it with clean bedding to prevent the growth of mold and mildew.
