How To Get a Urine Stain Out Of a Mattress: Step‑by‑Step Guide

If you’re searching for “How To Get a Urine Stain Out Of a Mattress,” you probably want something that works, doesn’t damage your bed, and helps with both stain and odor. This FAQ-style guide walks you through what to do, what to avoid, and how to prevent future stains.

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

For fresh accidents, acting quickly makes a big difference.

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

2. Apply a mild cleaning solution
Mix a simple solution at home:

  • 1 part mild liquid dish soap
  • 2 parts cool water

Lightly dab the solution onto the stained area with a clean cloth. Avoid soaking the mattress; too much liquid can be hard to dry and may cause lingering odors.

3. Rinse lightly
Dampen another cloth with plain cool water and gently blot the area to remove any soapy residue.

4. Dry thoroughly
Blot again with dry towels, then air-dry the mattress. If possible, open windows or use a fan. The mattress should feel completely dry before you put bedding back on.

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

Old urine stains are more stubborn because they’ve had time to set and can leave a noticeable odor.

1. Lightly re-dampen the stain
Use a spray bottle with cool water to slightly moisten the stained area. This helps loosen dried residue.

2. Use a gentle cleaning mixture
Many people find a mild water-and-vinegar solution helpful for dried stains and odor:

  • 1 part white vinegar
  • 2 parts cool water

Lightly spray or dab the mixture onto the stain. Let it sit for about 5–10 minutes so it can break down the stain.

3. Blot carefully
Blot with clean, dry towels until most moisture is removed.

4. Deodorize with baking soda
Sprinkle a thin, even layer of baking soda over the area. Leave it on for several hours, or ideally overnight, to absorb remaining moisture and odor.

5. Vacuum the baking soda
Once completely dry, gently vacuum up the baking soda using a hand attachment. Avoid harsh scrubbing, which could damage the mattress surface.

How do I get rid of the urine smell in addition to the stain?

When learning How To Get a Urine Stain Out Of a Mattress, odor control is often just as important as appearance.

  • Clean first, deodorize second. Remove as much of the stain as possible before trying to handle odor.
  • Baking soda is commonly used to help with mild smells after cleaning.
  • Repeat the vinegar-and-baking-soda routine if odor lingers, allowing full drying time between attempts.

Strong, persistent odors that don’t improve with home cleaning may require professional mattress cleaning or, in some cases, considering whether replacement is more practical.

Will these methods damage my mattress?

Most mattresses tolerate light, surface-level cleaning when done carefully:

  • Use cool or room-temperature water, not hot, to avoid setting stains.
  • Avoid soaking the mattress; too much liquid can damage internal materials.
  • Test any cleaning solution on a small, hidden area first to check for discoloration.

If your mattress came with care instructions, it’s wise to follow those first and stay within any guidelines given.

How long does it take a cleaned mattress to dry?

Drying time depends on:

  • How much liquid was used
  • Room temperature and airflow
  • Mattress thickness and materials

In many cases, it may take several hours to overnight to dry fully. To speed things up:

  • Open windows or use a fan
  • Remove bedding so air can circulate
  • Avoid sleeping on the mattress until it is completely dry to prevent odor and moisture buildup

Can urine stains on a mattress be completely removed?

Results vary based on:

  • How long the urine has been on the mattress
  • The type of mattress and cover
  • How deeply the liquid penetrated

Fresh stains often respond well to prompt cleaning. Older, set-in stains may fade but not always disappear completely. However, even if some discoloration remains, odor and hygiene can usually be improved significantly with careful cleaning.

How can I prevent future urine stains on my mattress?

Prevention can save time and frustration:

  • Use a water-resistant mattress protector to act as a barrier against spills.
  • Check Bedding regularly for dampness, especially in households with children or pets.
  • Address accidents quickly—the sooner you treat the stain, the easier it is to manage.
