How To Get Pee Off a Mattress: Step‑by‑Step FAQ Guide

If you’re searching “How To Get Pee Off a Mattress”, you’re likely dealing with a fresh accident or an older lingering stain. This guide walks you through exactly what to do, using common household ingredients and simple steps to clean, deodorize, and protect your mattress.

What should I do first when there’s pee on my mattress?

Acting quickly makes a big difference.

  1. Strip the bed
    Remove sheets, mattress protector, and any bedding right away so urine doesn’t spread.

  2. Blot, don’t rub
    Use clean, dry towels or paper towels to blot up as much liquid as possible. Press firmly, lifting and replacing towels as they become damp.
    Avoid rubbing, which can push urine deeper into the mattress.

  3. Keep the area as dry as you can
    The drier you get it before cleaning, the easier it is to remove stains and odor.

How do I clean fresh pee off a mattress?

For fresh stains, a simple water and mild detergent or vinegar solution often works well.

Basic cleaning method

  1. Mix a gentle solution

    • 1 part white vinegar to 2 parts cool water, plus a small amount of mild dish soap
      OR
    • Cool water with a small amount of mild detergent

  2. Lightly apply the solution
    Use a spray bottle or a clean cloth to lightly dampen (not soak) the stained area. Mattresses dry slowly, so avoid over-wetting.

  3. Gently blot again
    Blot with a clean cloth to lift urine and cleaning solution out of the fabric.

  4. Use baking soda for odor
    Sprinkle a thin, even layer of baking soda over the area. This can help absorb moisture and reduce smells.

  5. Let it dry completely
    Allow several hours, or more if needed. If possible, increase airflow with a fan or open window.

  6. Vacuum the baking soda
    Once dry, vacuum carefully to remove all powder.

How can I remove dried or old pee stains from a mattress?

Dried stains are more stubborn but can often be improved with patience and repeated treatments.

Deep-cleaning older stains

  1. Rehydrate the stain
    Lightly dampen the area with cool water or a water and vinegar mix (same ratio as above). Do not soak the mattress.

  2. Let it sit briefly
    Allow 5–10 minutes so the solution can loosen the dried urine.

  3. Blot and repeat as needed
    Blot, applying gentle pressure. You may need multiple rounds of applying solution and blotting.

  4. Use baking soda generously
    Cover the area with a bit more baking soda than you would for a fresh stain, as older smells can be stronger.

  5. Leave for several hours or overnight
    The longer baking soda can sit on a dry surface, the more odor it can absorb.

  6. Vacuum thoroughly
    Remove all visible powder and check for any remaining odor once fully dry.

How do I get rid of pee smell in a mattress?

Odor is one of the biggest concerns when people ask How To Get Pee Off a Mattress. Smell often lingers longer than the visible stain.

Odor tips:

  • Use vinegar and baking soda together
    Vinegar helps break down urine odor, while baking soda absorbs lingering smells.
  • Ensure complete drying
    A damp mattress can trap odors. Use fans or natural airflow to speed drying.
  • Repeat treatments if needed
    One round may not be enough for strong or older odors. Multiple light treatments are usually better than one heavy soaking.

Is it safe to use harsh chemicals or strong cleaners?

Many people wonder if they should use strong products when figuring out How To Get Pee Off a Mattress.

  • Mild is usually best. Strong chemicals can sometimes discolor fabric or leave their own lingering smell.
  • Test a small area first. If you try any cleaner you’re unsure about, test it on a hidden spot on the side or underside of the mattress.
  • Avoid over-saturating. Too much liquid, especially with stronger cleaners, can be hard to rinse out and slow to dry.

For most household situations, water, mild detergent, white vinegar, and baking soda are enough to handle typical urine stains.

How long does it take a mattress to dry after cleaning?

Drying time depends on how much moisture is used, your mattress type, and the room’s airflow.

  • Lightly treated spots can dry in several hours.
  • Heavier treatments or thicker mattresses may need a full day or longer.

Whenever possible, let the mattress dry completely before putting sheets back on. Trapping moisture can keep odor in and make the fabric feel damp.

How can I prevent future pee stains on my mattress?

Prevention is a common concern for anyone who has dealt with cleaning urine more than once.

  • Use a waterproof mattress protector. This helps keep liquid from soaking into the mattress layers.
  • Layer your bedding. Some people use a protector plus a washable mattress pad for easier cleanup.
  • Address accidents quickly. The faster you respond, the easier it is to clean and deodorize.
