How To Properly Clean Pee Out Of a Mattress: Step‑By‑Step FAQ Guide

If you’re searching for “How To Properly Clean Pee Out Of a Mattress”, you probably need a practical solution fast. This guide walks you through what to do right away, how to remove stains and odours, and what to avoid so you don’t damage your mattress.

What is the best first step when pee gets on a mattress?

Act as quickly as possible. Fresh urine is much easier to remove than dried stains.

  1. Strip the bed
    Remove all sheets, mattress protectors, and bedding. Wash them according to their care labels.

  2. Blot, don’t scrub
    Use clean, dry towels or paper towels to blot up as much liquid as possible. Press firmly, but do not rub.
    Rubbing can push urine deeper into the mattress layers.

  3. Keep liquids controlled
    Before using any cleaner, make sure the surface is only slightly damp. A very wet mattress dries slowly and can develop unwanted smells.

How To Properly Clean Pee Out Of a Mattress (Fresh Stains)

For a fresh urine accident, a simple home solution usually works well.

Step-by-step cleaning method

  1. Mix a gentle cleaning solution

    • Cool or lukewarm water
    • A small amount of mild liquid detergent or a gentle soap

    Stir to combine. Avoid harsh cleaners that may damage fabrics or irritate skin.

  2. Lightly apply the solution

    • Use a spray bottle or a clean cloth.
    • Dampen (do not soak) the stained area. The goal is to reach the urine without flooding the mattress.

  3. Blot again
    Use a fresh, dry towel to blot the area, lifting out the moisture. Repeat light spraying and blotting as needed.

  4. Neutralize odour with baking soda

    • Sprinkle a generous layer of baking soda over the damp area.
    • Gently spread it with your hand so it covers slightly beyond the stain.

  5. Let it sit
    Leave the baking soda on the mattress for several hours, or ideally overnight. The longer it sits, the more moisture and smell it can help absorb.

  6. Vacuum thoroughly
    Once completely dry, vacuum up all the baking soda using an upholstery attachment.
    Check that the area is dry to the touch before making the bed again.

Can you remove old or dried pee stains from a mattress?

Dried stains can be tougher, but you can often improve both the appearance and odour.

How to treat dried urine spots

  1. Re-dampen the stained area
    Lightly spray or dab with cool water. This helps loosen dried residue.

  2. Use a gentle cleaning solution
    Apply a mild soap-and-water mix as above. Let it sit for about 5–10 minutes, then blot.

  3. Repeat and be patient
    Older stains may need several rounds of light cleaning and blotting rather than one heavy application.

  4. Use baking soda again
    After blotting, add baking soda and let it sit for several hours before vacuuming.

If a stain is very old or extremely set in, it may not disappear completely, but the smell and intensity can often be reduced with repeated gentle cleaning.

What should you avoid when cleaning pee from a mattress?

Some common reactions can actually make things worse.

  • Avoid hot water
    Hot water may set some stains and make odours harder to remove.

  • Avoid harsh chemicals or unknown products
    Strong cleaners can damage mattress fabrics, break down foams, or leave lingering odours.

  • Avoid soaking the mattress
    Too much liquid can seep deep inside and be very slow to dry.

  • Avoid steam in most cases
    Steam can drive moisture and smell deeper into dense mattress materials.

How do you dry the mattress safely after cleaning?

Drying well is just as important as cleaning.

  • Increase airflow
    Open windows, turn on a fan, or use a gentle air setting to help the mattress dry.

  • Let it fully dry before making the bed
    The surface should feel completely dry, not cool or damp.

  • If possible, stand the mattress on its side
    This can help air reach more surfaces and speed up drying.

How can you prevent future pee stains on a mattress?

Once you know how To Properly Clean Pee Out Of a Mattress, prevention becomes the next priority.

  • Use a waterproof mattress protector to create a barrier between spills and the mattress.
  • Wash bedding regularly so any odours don’t linger.
  • Address accidents quickly whenever they happen to limit staining and smell.
