How to Get Rid of Bad Smell From Mattress – Apply These Secret Methods

What’s the best way to conduct mattress cleaning? Interestingly, we sleep about one-third of our lives, so it’s critical to keep our mattresses as clean and tidy as possible. Over time bacteria, stains, and odours can build up, which can cause potential health issues. The good news is you can take some basic steps to make your mattress looking and smelling fresh. You can even use some natural stain removers that are both safe and effective. In this guide, you will learn how to get rid of the bad smell from the mattress.

What Causes Mattress Stains & Odors

There are several different causes of stains/odors on mattresses. They include:

  • Body odor
  • Spills
  • Pets
  • Urine
  • Mold/Mildew

It’s quite common mattresses pads to start getting funky over time. In the situation of bed-wetting, you might have to deal with urine odors every week, for example. There are various other causes of stains/odors, including sweaty partner, smoker, or pets.


This process of cleaning a mattress through deodorizing might seem like a super-easy problem to fix. One of the main issues is picking a method that’s both safe and effective.

Many cleaners have strong artificial chemicals. They can cause a lot of unwanted issues like skin irritation. It can especially be a problem for people like me with sensitive skin.

There are other possible issues triggered by strong cleaners. They can give off fumes that can cause breathing issues. 

This can be worse for people with various conditions like asthma. Such people have a more sensitive respiratory system, so they’re more likely to have issues.

Top Causes of Smelly Mattresses

New Mattress 

This might be surprising since a brand new mattress causes it. The gas-like smell is some synthetic materials that function as fire retardants. These are added for the consumer’s protection, so they’re designed to be beneficial.

Another problem is that plastic bags that cover the mattresses trap the chemicals. So when the bag is removed, this causes the strong smells to be released.

These chemicals are referred to as volatile organic compounds (VOCs). Besides creating a strong odor, the VOCs can also trigger respiratory events like allergic reactions or asthma attacks among people with those conditions.


We love our pets but don’t always like the smells they produce. Cats and dogs can make smelly mattresses in different ways. For example, if it’s been a while since you’ve bathed Fluffy or Fido, then that could be the cause of a funky mattress.

Another possible explanation is the Proteus bacteria. The smell is somewhat like a corn tortilla and gets stronger when dogs sleep. Rocco & Roxie Supply Professional Strength Stain and Odor Eliminator is the best pet odor and stain remover.

Besides cleaning the mattress itself, be sure to clean the vacuum attachments. This will help ensure they’re functioning as effectively as possible, which is needed when vacuuming your mattress and other stuff.
