How Do You Clean Pee From a Mattress? Simple Steps That Actually Work

If you’re searching for “How Do You Clean Pee From a Mattress”, you’re likely dealing with a fresh accident or an old stain that won’t go away. This guide walks through what to do right now, what to avoid, and how to handle lingering odor and stains—without damaging your mattress.

What’s the Best Way to Clean Fresh Pee From a Mattress?

Fresh accidents are usually easier to handle. The goal is to remove moisture, lift the stain, and neutralize odor.

Step-by-step for fresh urine:

  1. Blot, don’t rub

    • Use clean, dry towels or paper towels.
    • Press firmly to soak up as much liquid as possible.
    • Avoid rubbing, which can push urine deeper into the mattress.

  2. Apply a gentle cleaning solution

    • Mix a solution of cool water and a small amount of mild liquid detergent or gentle soap.
    • Lightly dab the stained area with a clean cloth dipped in the solution.
    • Do not pour water directly on the mattress; too much moisture can be hard to dry.

  3. Rinse with minimal water

    • Use a separate cloth slightly dampened with plain cool water.
    • Blot the same area to remove soap residue.

  4. Use a deodorizing layer

    • While the mattress is still slightly damp, sprinkle a generous layer of baking soda over the area.
    • Baking soda helps absorb remaining moisture and odors.

  5. Let it dry completely

    • Leave the baking soda on for several hours, ideally until the mattress is fully dry.
    • Vacuum the baking soda thoroughly.

👉 For fresh accidents, speed matters. The sooner you act, the less likely the urine is to soak deeply and leave a lasting stain or smell.

How Do You Clean Pee From a Mattress When the Stain Is Old?

Dried urine can leave yellow stains and a lingering smell. Cleaning it may take more than one round.

To tackle dried or older stains:

  1. Lightly re-dampen the area

    • Use a spray bottle with cool water to lightly mist the stain.
    • This can help loosen dried residue without soaking the mattress.

  2. Use a gentle cleaning mix

    • A mixture of cool water and mild detergent can still work.
    • For tougher discoloration, some people use simple household ingredients like baking soda as a paste with a small amount of water, then gently blot after a short time.

  3. Blot and repeat as needed

    • Alternate between applying a small amount of cleaning solution and blotting it out.
    • Patience is important; several light treatments are better than one overly wet one.

  4. Deodorize thoroughly

    • After cleaning, apply a fresh layer of baking soda, leave it for hours, then vacuum.
    • Strong odors sometimes need more than one deodorizing cycle.

Older stains may not disappear completely, but many people find they fade noticeably and odors become far less obvious with consistent, careful cleaning.

How Do You Get the Urine Smell Out of a Mattress?

Even if the stain is lighter, odor can linger. When people ask “How Do You Clean Pee From a Mattress”, odor removal is usually a major concern.

To reduce or remove smell:

  • Clean first, deodorize second
    Removing residue helps any deodorizer work better.

  • Use odor-absorbing powders

    • Baking soda is a common choice because it can help absorb both moisture and smell.
    • Spread it over the entire affected area, not just the visible stain.

  • Allow long contact time

    • Leaving baking soda on for several hours (or even overnight) tends to be more effective than a quick sprinkle and vacuum.

  • Air out the mattress

    • If possible, place the mattress in a well-ventilated room.
    • Good airflow can help lingering odors dissipate more quickly.

If odor remains after cleaning and deodorizing, repeating the process can gradually improve it.

What Should You Avoid When Cleaning Pee From a Mattress?

Certain habits can make the problem worse or shorten your mattress’s life.

Avoid:

  • Soaking the mattress
    Too much liquid can seep deep inside, making drying difficult and potentially leading to long-term odor or damage.

  • Harsh scrubbing
    Vigorous scrubbing can damage fabric and push urine deeper into the layers.

  • Strong, untested chemicals
    Aggressive cleaners may discolor fabrics or leave their own strong smell behind.

  • Using hot water
    Hot water may set some stains, making them harder to remove.

Can You Prevent Future Pee Stains on a Mattress?

You can’t always stop accidents, but you can protect the mattress to make cleanup easier next time.

Common approaches include:

  • Using a washable, waterproof mattress protector as a barrier.
  • Adding an extra removable cover that can be washed more frequently.
  • Keeping extra sheets and protectors on hand for quick changes during the night.

These steps don’t stop accidents, but they can keep urine from reaching the mattress in the first place.
