How to get urine out of a mattress: stained mattress

There comes a time when every parent wonders how to get urine out of mattress. 

So, you let your child have just a little bit too much watermelon, or perhaps he drank too much of his favorite tea just before sleep - if you're a parent or have been growing up with younger siblings, you probably already know where this is going. 

Yep, it’s 3 AM and you hear a faint voice saying “Mommy, I’ve wet the bed…” We’d probably all agree that it’s not the most pleasant surprise.

You throw the child’s pajamas into the washing machine, change the child into fresh ones, strip the bed, and throw it all into the washing machine, too. But what do you do with the mattress? It’s not very washing machine-friendly, is it? So... Do you have to buy a new mattress now?

Well, sadly, it isn’t machine-washable. Therefore, you’ll have to come up with a different way of getting urine out of mattress. I admit, it doesn’t seem like such an easy task at first, but I’m here to help you with that. Follow this guide and you’ll find out how to get urine out of mattress easily. 

What is Urine Made out of?

Before you start the battle of learning how to get pee out of a mattress, you must first find out what you’re fighting against. While we might think we know what pee is, do we really? Well, it’s a liquid that comes out of your urethra, but what is it made out of?

Human urine is 95% water and 5% urea[1], a waste product made in the liver. It’s usually rather clear with a hint of yellow and the smell isn’t usually too strong, unless it has dried out. However, if you’ve ever forgotten to consume the needed amount of liquids, you might have noticed that it tends to become darker, sometimes even with a hint of orange.

The same goes for fish, onions, asparagus[2] and quite surprisingly, brussel sprouts. So, monitor your food first if you notice foul-smelling urine. 

Another factor that we’ve mentioned before when talking about the colour that also influences the smell is dehydration.

We can’t just not mention it before getting to the part of how to get urine out of mattress. When you’re dehydrated the ratio of water to urea changes, making the percent of urea higher in your urine, resulting in a foul smell. So, don’t forget to drink your water!

Prepare the Mattress

Make the Mixture

Spray the Solution and Leave it to Dry
