How To Get Mold Out Of A Mattress Guide

And how do they know they have mold? The answer comes down to one specific sign – a musty smell. And while that is not the only indicator that you are dealing with mold, it does indicate that there may be a problem with your mattress. This article will give you vast information about mold in your bedroom, as well as a step-by-step guide on how to get mold out of a mattress.

How Does Mold In The Mattress Appear?

We talk a lot about mold in the house, but what about mold in your mattress? How is that possible? The answer to that question involves a lot of different factors. There are many ways that mold can appear in your bed, but here are some of the most common:

Moisture In Your Mattress

Moisture can come from too much humidity in and around your house (which will cause mold problems with wallpaper, ceiling tiles, and more).

Your Mattress Is Old

This should be an obvious one, but if you are sleeping on a mattress over ten years old, it is not doing your body any favors. And if it was made with cotton instead of memory foam, that could be causing some real problems for your back and neck (along with the mold problems we will get into later).

You Have Pets

You may love your furry friend more than anything else in the world, but they shed their dander which can cause allergies, asthma, and even mold in a mattress.

How To Get Mold Out Of A Mattress: 5 Easy Steps

Now that you know some common factors to mold in a mattress let’s talk about how to do something about it. These steps will work for all ages of beds, and they are very easy to follow.

Vacuum A Mattress

You can vacuum your mattress from both sides with your regular vacuum cleaner – you don’t have to have anything special. But if you do own an air pump, then that is what I would recommend using (it can suck the air out of small crevices). Do not use a brush attachment for this job because the fibers from the brush will get caught in the foam and cause more problems than it was trying to help with.

Scrub The Moldy Area With Rubbing Alcohol Solution

Now that your mattress is vacuumed, you can move on to the scrubbing. You will need plenty of rubbing alcohol (preferably isopropyl—that will probably be easier to find) to help with this process. So what you need to do is mix one part rubbing alcohol with two parts water in a spray bottle.

Then spray the mixture on your moldy area and let it sit for ten minutes or so. It may seem counterintuitive, but letting the mixture sit will help kill the mold better than if you were just spraying it on (the rubbing alcohol solution also dries faster).

Rinse With Cold Water

Now that the rubbing alcohol has sat on your mattress, it is time to rinse it off. You may think that this would be enough on its own to help get rid of the mold, but you should always rinse with cold water (to prevent spreading the mold spores).

You do not have to flush out a large amount of water – just create a gentle stream with your hose or faucet and let it run for 30 seconds or so. You can also use a cloth or a sponge to clean the mattress surface.

Spray On A Disinfectant

You will need to spray on a disinfectant after scrubbing the mold away and rinsing it with cold water. The easiest thing to do is to go with bleach – that is a little strong, but it seems to do the job well. Ideally, you should mix one part of bleach with four parts of water in a spray bottle and then use that on your mattress.

Air Dry The Mattress

Finally, you want to let your mattress dry completely before returning it to your bedroom. It will be better to use direct sunlight to boost the drying process.

How To Prevent Mold Recurring In Your Mattress?

If you follow these steps correctly, then your problem with mold in your mattress should be over. But if you want to prevent mold from ever happening again, the best thing you could do is make sure the bed is used and treated correctly.

Remove Excess Moisture

One of the best things that you can do to prevent mold is to make sure that excess moisture is removed from your room and mattress. You will want to take the most care when dealing with this step because you do not wish any mold spores (which are microscopic bits) released into the air.

Clean Air With A Purifier

This one is very easy to do, and it will not take very much time at all. You can purchase a small air purifier that uses UV lights to kill mold spores and then keep this near your mattress (preferably right under the box).

That way, any time you have an issue with moisture or mold (which is probably more often than you realize), you can use this air purifier to kill all of the mold spores that may be in the air.

Keep Good Airflow In The Bedroom

Another thing you can do to help prevent mold is to keep good airflow through your bedroom. This will ensure that the air in the room does not become trapped and that there is no excess moisture in the room.
