Ingredients You Need

  • White Vinegar
  • Baking Soda
  • 3% Hydrogen Peroxide
  • Dishwashing Detergent (Dish Soap)

Step-by-Step Guide

Step 1: Blot the Urine

If the urine is fresh, use paper towels to soak up as much as possible. Press down firmly to absorb the moisture deep within the mattress. You might need to stand on the towels for extra pressure. If you have a wet/dry vacuum, use it to extract moisture. If the urine is dry, move to the next step.

Step 2: Neutralize Odor with Vinegar

Mix a solution of equal parts vinegar and water. Pour about 50 ml over the urine area. Blot with paper towels or use a vacuum to soak up the solution.

Step 3: Sprinkle Baking Soda

Sprinkle a good handful of baking soda over the affected area.

Step 4: Apply Hydrogen Peroxide Mixture

In a jug, mix a quarter cup of 3% hydrogen peroxide with a teaspoon of dish soap. Drizzle this over the baking soda and gently work it in with your fingers or a brush. Wait 15 minutes before blotting or vacuuming again.

Step 5: Dry the Mattress

Allow the mattress to dry completely. You’ll know it’s dry when the baking soda feels dry. Vacuum up the baking soda thoroughly. If possible, dry the mattress in the sun or use a fan, heater, or hair dryer to speed up drying.

Preventative Tip

To prevent future accidents, consider placing a plastic tarp over your bed. Cats don’t like the feel and it will protect your mattress.

Conclusion

And that’s it! With these steps, your mattress can stay clean and fresh.
