How To Clean Urine Stains Off a Mattress: Step‑by‑Step FAQ Guide

If you’re searching for How To Clean Urine Stains Off a Mattress, you’re likely dealing with a fresh accident or a lingering stain and smell. This guide walks you through simple, at‑home methods to tackle both fresh and dried urine stains, along with common questions people ask in this situation.

What’s the best way to clean fresh urine off a mattress?

When the stain is fresh, acting quickly gives the best chance of removing both the mark and the odor.

Step 1: Blot, don’t scrub

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

Step 2: Apply a mild cleaning solution
A simple option many people use at home:

  • Mix equal parts cool water and white vinegar in a spray bottle or bowl.
  • Lightly spray or dab the solution onto the stained area.
  • Let it sit for about 10–15 minutes.

Step 3: Blot again

  • Use dry towels to blot up the vinegar solution and any remaining moisture.
  • Repeat until the area feels only slightly damp.

Step 4: Use baking soda to absorb moisture and odor

  • Sprinkle a generous layer of baking soda over the damp spot.
  • Leave it for several hours, or overnight if possible, to absorb moisture and smell.
  • Vacuum thoroughly to remove the baking soda.

This approach answers the core of How To Clean Urine Stains Off a Mattress when the stain is new and still wet.

How do you remove dried or old urine stains from a mattress?

Dried stains can be more stubborn and may have a stronger odor, but you can still improve or remove them with a bit more effort.

Step 1: Lightly re-dampen the area

  • Mist the stained area with cool water.
  • You want it slightly damp, not soaked.

Step 2: Use a targeted cleaning mix
Common at‑home option:

  • Mix about 1 part white vinegar to 2 parts water.
  • Optionally add a small amount of mild dish soap.
  • Apply to the stained area with a spray bottle or cloth.

Step 3: Let it sit and break down the stain

  • Allow the solution to sit for 15–30 minutes.
  • Blot with clean towels to lift out the loosened urine.

Step 4: Deodorize with baking soda

  • Sprinkle baking soda thickly over the treated spot.
  • Leave for several hours or overnight.
  • Vacuum well.

If some discoloration remains, the stain may be partly set in the mattress materials. In those cases, reducing smell and lightening the stain is often the most realistic outcome.

How do I get urine smell out of a mattress?

Even when the stain looks gone, odors can linger. To focus on smell:

  • Airflow helps: Leave the mattress uncovered in a well‑ventilated room.
  • Repeat baking soda: Another round of baking soda, left for several hours and vacuumed, can continue to absorb odors.
  • Avoid heavy perfumes: Strong fragrances may just mask the smell temporarily instead of addressing it.

For persistent odors that don’t improve with cleaning, some people consider professional cleaning services that specialize in upholstery and mattresses.

Can I use bleach or harsh chemicals on my mattress?

In most cases, bleach and very strong chemicals are not recommended for mattresses because they can:

  • Discolor fabrics
  • Weaken materials
  • Leave strong, lingering odors

Instead, milder, water‑based solutions are commonly preferred. Always check your mattress care tag and test any cleaner on a small, hidden area first.

How should I dry the mattress after cleaning?

Proper drying is important to avoid musty smells and moisture issues.

  • Use fans: Place a fan near the mattress to speed up drying.
  • Open windows: Good airflow helps moisture evaporate.
  • Avoid direct heat: High heat sources can damage mattress materials.

Only remake the bed once the mattress feels completely dry to the touch.

How To Clean Urine Stains Off a Mattress: Common Mistakes to Avoid

  • Soaking the mattress: Too much liquid can push urine deeper and make drying harder.
  • Rubbing the stain: This spreads the stain and drives it in.
  • Skipping the baking soda: Without an absorbent step, odors are more likely to linger.
  • Covering it too soon: Putting bedding back on a damp mattress can trap moisture.
