How to Get the Pee Smell Out of a Mattress

If you’ve already cleaned up your mattress but it still smells of urine, there are a few different things you can try. As outlined in our mattress cleaning guide, simply spreading baking soda out over the mattress is surprisingly effective. Baking soda is unique in that it actually absorbs odors, rather than just masking them. The basic pH of baking soda helps to neutralize the generally acidic odors of urine, while its tendency to absorb liquid helps to draw out any remaining moisture. For best results in neutralizing urine odors in your mattress, spread a thin layer of baking soda out over the entire mattress surface. If a specific area smells more strongly, you can use a slightly thicker layer of baking soda. Allow the baking soda to sit, uncovered, for 5 to 10+ hours, and then vacuum it. Repeat as needed. Another option is to use a vinegar solution, as discussed above. Use a 50/50 mixture of cold water and distilled white vinegar. You can also consider adding a few drops of an essential oil, such as lavender or eucalyptus, to help cover up any unpleasant smells. Apply it to the surface of your mattress using a spray bottle, and allow it to air-dry fully. Then, use baking soda to remove any remaining moisture, and to neutralize the strong vinegar smell from the cleaning solution. Keep in mind that pet stains may require a stronger cleaning solution with enzymes that remove lingering odors. This will help prevent pets from marking their territory again. Enzyme cleaners can be found in many pet stores
