Cleaning Urine from Mattress

When it comes to cleaning urine from mattresses, there are two situations that you might need to tackle. They are wet and dry stains, and they will call for different cleaning methods and using various agents.

While the right idea is always to clean the urine when it is still fresh, this cannot always be possible, and sometimes you will realize that the mattress has a urine stain a week or even much later. But here is how to deal with both wet and dry urine stains.

Wet Stains

  • Step #1: Remove All the Linens

With a fresh urine stain, the first thing should always be to remove the linens from the bed. And when doing this, you should avoid the temptation to try and wipe out some of the urine with the sheets.

Doing this will only spread the urine, and it can even help it sink deeper into the mattress. You would hate for this to happen.

  • Step #2: Blot up the Urine

After removing everything from the mattress, the next step is to blot up the urine and make sure you soak up as much as possible. You can use a sponge to do this or your cotton towel if you do not have any sponge. As you do this, it is essential to go over the entire area as many times as possible, and if your towel or sponge gets saturated, you should use a new one or wring it if you can.

  • Step #3: Dampen the Area

The next step after soaking up as much urine as possible is to dampen the area. Doing this dilutes the urine and helps to get rid of the odor. You can use rubbing alcohol for this because it will also kill the bacteria in the urine.

So what if you do not have rubbing alcohol?

Vinegar too does an excellent job at this stage. After dampening as much as possible, you should then blot out as much of the liquid as possible. Repeat the dampening and blotting up as many times as possible or until the urine odor vanishes completely. Simple, isn’t it? But, you still need to dry the mattress.

  • Step #4: Leave the Mattress to Dry

The last step is to dry the mattress, and it is as important as all the others. For this, you can open the windows or turn on the fan. If possible, you can even dry it out in the sun because the fresh air outside will also help to dampen the smell of the urine and cleaning agents.

Dry Stains

  • Step #1: Dampen the Stained Area

For dry stains, the first step is to dampen the area to make it possible to clean. But when doing this make sure that you do not saturate it with water because the wetness will spread the urine. And what’s worse than this? The idea should only be to dampen it enough to reduce the strength of the stain and dissipate some of the odor.

  • Step #2: Sprinkle Some Borax/Baking Soda

Covering the stained area with borax helps to neutralize the odor. And so you should make sure that you sprinkle the stain with lots of borax and spread it out well.

But, as you do this you should make sure that you do not leave it on your skin as it can irritate it. You should then rub it into the stain. If you do not have borax, you can use baking soda but also make sure you rub it into the stain.

  • Step #3: Allow the Borax/Baking Soda to Dry

Allow the mattress to dry completely out in the sun, but if this is not possible, you should keep it in a well-ventilated room without a lot of moisture. Note that this might take the entire day. Even so, you can still speed up things by turning on the fan and opening all the windows and doors in the room

  • Step #4: Vacuum up the Borax/Baking Soda

If you were using baking soda, you might not need to vacuum it because keeping some between the sheets and mattress will trap any odors in there. But, if you used a lot of borax or baking soda you need to vacuum it and once you do this, the mattress should be clean again free from urine stains and smell.
