How To Dry a Mattress

Not only is a wet mattress inconvenient, but it also breeds mold and mildew. A wet mattress quickly develops a musty odor, and within a day or two, mold may begin to form deep within it.

Don’t worry, regardless of how your mattress became wet, you can simply dry it with a few simple steps.

Not every soaked mattress can be saved. If the mattress was flooded, the water was most likely contaminated with biohazards, hazardous chemicals, or gasoline. Even if you sanitized the inside of the mattress thoroughly, mold from leftover moisture could infiltrate the mattress undetected.

Tips for Drying Your Mattress

To dry your mattress as fast as possible, use direct sunlight and air movement. Then cover the mattress with a waterproof mattress cover so that you may chuck it in the washing machine the next time it gets wet.

If the mattress is only partially wet from a small spill, there’s a good chance it can be salvaged, as long as you work fast and dry it thoroughly.

Soak up the Moisture With Clean Dry Towels

If a spill or leak occurs, press a clean, dry cloth into the mattress as soon as possible to absorb the liquid. Once your towel is damp, replace it. Attempt to assimilate as much liquid as possible.

Use Kitty Litter or Baking Soda For Big Spills

To help suck most of the residual moisture out of your mattress, try baking soda, kitty litter, or salt. Use whatever you have on hand, however salt is preferred over baking soda or kitty litter.

For larger spills, kitty litter is the best option. Apply one of these chemicals to the affected region, rubbing it in with a toothbrush or pressing it in with your hands. This ensures that the interior layers, not just the surface region, dry fast.

Allow for up to 12 hours of absorption before moving on to the next stage. As the chemical absorbs moisture, it should clump up, indicating that it is working.

To Absorb Excess Fluids Use a Wet/Dry Vacuum

A piece of your mattress may be damp if rain blew in through the window. To suck up the liquid, turn on a wet/dry vacuum and run the nozzle over the damp sections of the mattress in long, even strokes.

You don’t want to touch your mattress with a vacuum nozzle that’s been trapped in spiderweb-filled areas of the garage, so disinfect it first. Simply wipe it inside and out with an antiseptic wipe and let it dry.

Put the Mattress on its Side

Turn the mattress on its side and secure it in position, leaving at least 2 feet of air space on both sides. Place a fan at the end, blowing down both sides, or use two fans, one on each side, aimed straight at the mattress.

To create as much air flow in the space as possible, open windows and switch on ceiling fans, if applicable. A space heater placed at a safe distance from the mattress can also assist speed up the drying process.

Use a Fan, Dehumidifier, or Space Heater

It’s critical to promote optimum air circulation, so make sure the mattress is propped up on the ground with the most surface area visible. It can also be placed on top of saw horses or cinder blocks to expose as much surface area as feasible.

Allow it to dry for up to 24 hours before bringing it inside for the night to avoid further moisture exposure from dew or inclement weather.

Finally, be patient and wait until the mattress is entirely dry before sleeping on or using it. Premature use can stifle the drying process, undoing all of your efforts.

Use Sunlight to Help Dry the Mattress

Sunlight is a natural sanitizer and one of the best ways to completely dry your mattress. If possible, dry and sterilize your mattress outside in the sun.

Place the mattress on its side, lying against the wall and supported by small blocks. It’s critical to allow as much air as possible to circulate through the mattress. A dehumidifier and fans should suffice in instances where the mattress cannot be dried in direct sunshine. It’s best not to use the mattress until it’s entirely dry, as this can lead to mold growth.

When drying a mattress yourself, take extra precautions to sterilize it and ensure that all moisture is removed. After cleaning, keep an eye out for symptoms of mold growth and foul odors.

How to Prevent Mold From Forming on a Wet Mattress

Even if the outside appears to be dry, the inside of the mattress may be damp. Allow it to air dry rather than allowing it to remain damp in the interior. Any moisture can soon turn to mold and mildew, putting your or your family’s health at risk.

Wipe the mattress surface with a solution of half rubbing alcohol and half water to make a mold-inhibiting sanitizing wipe. Avoid soaking the mattress, since this will just make the moisture problem worse.

To get rid of the baking soda, vacuum your bed with the upholstery attachment.

How to Dry a Mattress With a Hair Dryer

If you spill water on your mattress and the absorbent method didn’t work for you, you can dry it with a towel and your hairdryer.

To absorb the water, press the cloth into the mattress. Then, for ten to twenty minutes, wave your hairdryer over the damp patch. Allow the area to cool before checking for dryness.

The hairdryer produces a direct stream of warm air that can penetrate deeper layers of the skin and remove moisture.
