When it comes to mattress stains, there is one specific type that occurs more often than not, and yet people avoid mentioning it directly. It’s dirty and awkward. From children and pets? Totally understandable. But from you? We don’t judge, but most people will. We are talking about urine accidents. Are you searching for a helpful and straightforward guideline on dealing with these smelly smudges? You’ve got it. This article will show you the way to remove urine stains from your mattress.

Urine stains – The issues

How to Remove Urine Stains from MattressOne, every stain should be tended to as soon as possible. But as we have previously mentioned, bed-wetting incidents are rather embarrassing to approach, especially for children who are unable to clean by themselves yet afraid of being scolded. By the time the trouble is reported, the urine has got into the mattress or mattress topper and settled there, making it extra difficult to remove.

Two, the main component of urine is uric acid, which has an ugly color and an obnoxious smell. Removing the yellow remnants and getting rid of the odor? Not a fun task to do but not impossible either.

How to clean urine stains on mattresses


  • A few pieces of clean cloth
  • Spray bottle
  • Baking soda
  • Hydrogen peroxide
  • Laundry detergent
  • Vinegar

If this unwanted accident happens to you, the very first move of yours should be trying to blot the wetness as much as you can. You can use a sponge, a paper towel, or a wet/dry vacuum, but be careful and avoid rubbing the stain too hard. This will get the urine sinking deeper when our purpose is the total opposite. Then you strip the bed bare and wash the cover right away.

If you didn’t take care of the issue immediately, vinegar would be the best assistant. Blot the vinegar until it’s dry, then you can move onto the next instruction.

Sprinkle baking soda on the stained area to absorb any moisture remaining. When the powder changes its color, you might vacuum it up and repeat the step until the white shade doesn’t darken anymore.

That’s when the stain is new and wet. What if it has dried up already?

Prepare a mixture of hydrogen peroxide (8 oz), baking soda (3 tablespoons), and liquid detergent (several drops) in a spray bottle. Some articles recommend essential oils for a nice fragrance, but we don’t. We are doing our best to free the mattress from the ammoniac odor, therefore the oil scent is likely to be removed as well.


  • Do not shake the bottle vigorously. We don’t want a mess of bubbles to clean up in addition to the pee stain, do we?
  • This mixture is a strong bleach, you might want to use it on white mattresses only. For colored ones, white vinegar is a good alternative.
  • Our solution also works on bloodstains.

Target the spots by dipping the cloth into the mixture and dabbing the stain. Be generous with the amount you apply on the mattress, but do not soak it, or it will take longer to dry.

What if the stain is more wayward than you think? Try this dry foam solution of dry laundry powder (3 tablespoons) and water (15ml). You will get a paste after mixing them evenly. Spread it over the stain.


  • Be cautious with the laundry powder you use! If there is an oxygenated component, it can do harm to the mattress.
  • Consider an enzymatic cleaner if the culprit to your dirty mattress is a pet. It’s better at neutralizing odors.

Wait for the dry foam to settle before scraping it off with a spoon. You have been very careful and gentle through the process above, keep it up with this nearly final step, unless you want to damage the mattress.

Use the baking soda once more to get rid of the annoying smell of ammonia and laundry detergent. To dry out thoroughly, it needs about 18 hours. Hence, you should find another sleep arrangement and give it a whole night for the best result.

Vacuum to ensure the baking soda and the dry foam are all lifted off the mattress. With the nozzle, you can reach into the smaller crevices.
