How To Get Urine Off Of a Mattress: Simple Steps That Actually Work

If you’re searching for “How To Get Urine Off Of a Mattress”, you’re likely dealing with a fresh accident or an old stain that won’t go away. This guide walks you through practical, at-home methods to clean urine from a mattress, reduce odor, and protect your bed for the future.

Why urine is hard to remove from a mattress

Mattresses are made of absorbent materials like foam and fabric. When urine soaks in, it can:

  • Spread below the surface, not just on the top layer
  • Leave a lingering odor if it dries inside the mattress
  • Cause discoloration that gets harder to remove over time

Cleaning quickly and using the right technique makes a big difference.

How To Get Urine Off Of a Mattress: Step-by-step for fresh stains

1. Act fast and blot, don’t rub

Use clean, dry towels or paper towels to blot up as much liquid as possible. Press firmly to pull moisture out of the mattress.

  • Do not scrub or rub — this can push urine deeper into the foam.
  • Work from the outside of the stain inward to help keep it from spreading.

2. Apply a gentle cleaning solution

A common approach is to use a mild mixture of water and a gentle cleaning agent such as a small amount of dish soap or a light detergent.

  1. Mix cool or lukewarm water with a small amount of cleaner.
  2. Lightly dampen (don’t soak) a clean cloth in the solution.
  3. Gently dab the stained area, focusing on the visible urine spot.

Avoid over-wetting the mattress. Too much moisture can be slow to dry and may create additional odor issues.

3. Rinse lightly

Use a second cloth dampened with plain water to dab the area and help remove any remaining cleaning solution. Again, avoid saturating the mattress.

4. Dry thoroughly

Proper drying is one of the most important steps when learning How To Get Urine Off Of a Mattress.

  • Press dry towels on the damp area to remove excess moisture.
  • Allow the mattress to air dry completely in a well-ventilated room.
  • If available, use a fan to speed up drying.

Make sure the mattress is fully dry before putting bedding back on.

How to deal with dried or old urine stains

Older urine stains can be more stubborn. The steps are similar, but you may need to repeat the process.

1. Lightly re-dampen the area

Use a small amount of clean water on a cloth to re-moisten the stained area. This can help loosen dried residue so it’s easier to lift out.

2. Clean gently and patiently

Follow the same steps as for fresh stains:

  • Blot with a mild cleaning solution
  • Rinse with a damp cloth
  • Blot dry and allow extended drying time

Old stains may lighten gradually rather than disappear all at once. Repeating the process can sometimes improve the result.

How can I reduce urine odor from a mattress?

Even after cleaning, a slight odor may remain, especially with older stains. Some general tips:

  • Make sure the mattress is completely dry. Lingering dampness can trap smells.
  • Allow the mattress to air out by removing covers and letting it breathe.
  • Keep the room ventilated with open windows or a fan when possible.

If odor persists after cleaning, repeating the process or using a specially formulated mattress-safe cleaner may help.

Can I save a mattress after a large accident?

In many everyday situations, a mattress can still be used after a urine accident, especially if:

  • You clean as soon as possible
  • You avoid soaking the mattress with water or cleaner
  • You allow for thorough drying between each step

However, very large or repeated accidents can lead to deeper staining and more noticeable odors. In those cases, some people choose to clean as much as possible, then monitor whether the mattress still feels and smells acceptable over time.

How do I prevent future urine stains on my mattress?

Once you’ve gone through the work of learning How To Get Urine Off Of a Mattress, it’s natural to want to avoid repeating it. Consider:

  • Using a waterproof mattress protector to keep liquids from soaking into the mattress surface
  • Layering absorbent pads under sheets in situations where accidents are more likely
  • Checking the mattress regularly so small accidents don’t become long-standing stains

These simple steps can make any future cleanup much easier.

❓ Common questions about cleaning urine from a mattress

Will urine permanently ruin my mattress?

Not always. Many mattresses can be successfully cleaned after a urine accident, especially if treated quickly. There may still be slight discoloration even when the smell and moisture are gone, but the mattress can remain usable.

Can I use very hot water or harsh cleaners?

Very hot water or strong chemicals may:

  • Be too harsh on some mattress materials
  • Spread the stain if used in excess
  • Leave residues that are difficult to rinse out

Gentler, minimal-moisture methods are usually more mattress-friendly.
