How Do You Get Urine Out Of a Mattress? Step‑by‑Step FAQ Guide

If you’re searching for “How Do You Get Urine Out Of a Mattress”, you’re likely dealing with a fresh accident or an old stain and want it gone fast—smell and all. This guide walks through what to do, what to avoid, and how to protect your mattress going forward.

What’s the best way to get fresh urine out of a mattress?

For fresh accidents, acting quickly makes a big difference.

Step-by-step method:

  1. Blot, don’t rub

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

  2. Apply a gentle cleaning solution
    A common home option is:

    • Mix equal parts cool water and white vinegar in a spray bottle.
    • Lightly spray the stained area until damp, not soaked.
    • Let it sit for 10–15 minutes to help break down the urine.

  3. Blot again thoroughly

    • Use fresh towels to absorb the vinegar solution and remaining moisture.
    • Continue until the area feels only slightly damp.

  4. Use baking soda for odor control

    • Sprinkle a generous layer of baking soda over the damp area.
    • Gently spread it so it fully covers the stain.
    • Leave it on for several hours, ideally overnight.

  5. Vacuum the baking soda

    • Use the upholstery attachment if you have one.
    • Go over the area slowly to pick up all the powder.

This approach helps with both visible staining and lingering odors in most fresh cases.

How do you get dried or old urine stains out of a mattress?

When people ask “How Do You Get Urine Out Of a Mattress”, they often mean set-in stains that have already dried. These can be more stubborn but are still worth treating.

For dried stains:

  1. Lightly re-dampen the area

    • Mist the stained area with plain water or a diluted vinegar solution.
    • The goal is to loosen the dried residue, not soak the mattress.

  2. Use an enzyme-based cleaner (optional)

    • Enzyme cleaners are commonly used for urine on soft surfaces.
    • Follow the label instructions and test on a small, hidden area first.
    • Allow the product to sit for the recommended time.

  3. Blot thoroughly

    • Press with clean towels to draw out moisture and loosened residue.

  4. Apply baking soda and vacuum

    • As with fresh stains, coat the area with baking soda.
    • Let it sit for several hours, then vacuum.

Old stains may need more than one treatment. If a faint odor or mark remains, repeat the process rather than using harsh chemicals that can damage the mattress materials.

Will the urine smell ever completely go away?

Urine odor can be persistent, especially if it has soaked deep into the mattress, but odors usually improve significantly with proper cleaning.

To maximize odor removal:

  • Treat the area as soon as you notice it, even if it’s already dry.
  • Allow full drying time before putting bedding back on.
  • Use baking soda generously, as it helps absorb smells.
  • Consider repeating the treatment if any odor lingers.

Strong perfumes or air fresheners may cover the odor temporarily but do not remove the source inside the mattress.

What should you avoid when cleaning urine from a mattress?

When learning how to get urine out of a mattress, knowing what not to do is just as important:

  • Don’t use hot water

    • Heat can cause urine to set further into fibers and make odors harder to remove.

  • Don’t soak the mattress

    • Too much liquid can penetrate deep layers and be slow to dry, potentially leading to other issues.

  • Avoid harsh chemicals or bleach

    • These can discolor fabrics or break down foam materials.
    • Strong fumes may also be unpleasant in a bedroom.

  • Skip steam cleaning for most mattresses

    • High heat and moisture may not be compatible with certain mattress materials.

How long does a mattress take to dry after cleaning?

Drying time depends on how much liquid was used and the room environment.

To help it dry faster:

  • Increase airflow with open windows or a fan.
  • Use a low, cool setting on a hair dryer if needed, keeping it moving.
  • Avoid covering the area with sheets or a mattress protector until fully dry.

Many mattresses feel dry to the touch in a few hours, but deeper layers may take longer, so giving extra time is helpful.

Can cleaning urine damage a mattress?

Gentle, water-based cleaning with blotting and baking soda is generally safe for most mattress types. Potential issues usually come from:

  • Over‑soaking the mattress
  • Using strong chemical cleaners
  • Applying high heat

If your mattress came with care guidelines, it can be useful to check any cleaning instructions before using new products.

How can you prevent future accidents from ruining your mattress?

The easiest way to avoid repeating the question “How Do You Get Urine Out Of a Mattress” is to add a layer of protection:

  • Use a water-resistant mattress protector to create a barrier.
  • Choose removable, washable bedding that’s easy to clean quickly.
  • If accidents are common, keep cleaning supplies (towels, spray bottle, baking soda) handy.

Protective layers help keep liquids from reaching the core of the mattress, making clean-up simpler and faster.
