Why Cleaning Your Foam Mattress Matters

Health Benefits

Cleaning a foam mattress thoroughly after bedwetting not only helps maintain comfort but also promotes a healthy sleeping environment. Urine can contain bacteria and create an ideal breeding ground for mold and mildew if left untreated. These can lead to allergies and respiratory issues, especially in sensitive individuals.

Prolongs Mattress Life

Investing in a good mattress isn’t cheap, and proper maintenance can extend its lifespan. Promptly cleaning accidents prevents the foam from deteriorating and keeps odors at bay, ensuring you get the most out of your investment.

Peace of Mind

There’s nothing worse than lying down on a mattress that smells or feels dirty. A clean mattress provides peace of mind and allows for better, more restful sleep. Knowing you have a quick and effective cleaning method in place can alleviate stress when accidents happen.

Needed Materials

Before diving into the cleaning process, gather the following materials to ensure you have everything on hand:

Paper Towels or Clean Clothes:

These will be used to absorb excess liquid before cleaning the mattress.

Enzyme Cleaner:

An enzyme cleaner is specifically designed to break down and eliminate urine stains and odors effectively. Look for one that is safe for use on foam mattresses.

Baking Soda:

Baking Soda is a Natural Deodorizer

Baking soda is a natural deodorizer that can help neutralize any lingering odors.


A vacuum with an upholstery attachment will be useful in removing any remaining baking soda after the cleaning process.

Optional Materials

Plastic Gloves:

If you prefer to avoid direct contact with the mattress, disposable plastic gloves can be used when handling any soiled areas.

Essential Oils:

For a refreshing scent, consider adding a few drops of your favorite essential oil to the baking soda before sprinkling it on the mattress.

Having these materials ready will streamline the cleaning process and make it more efficient.

10 Step-by-step Guidelines on How to Clean Foam Mattress After Bedwetting

Step 1: Act Quickly

The sooner you address the bedwetting accident, the better. Fresh urine is easier to clean and less likely to cause stains or lingering odors. As soon as you notice the wet spot, remove any bedding and start the cleaning process.

It’s best to avoid leaving the spot unattended for too long. You may also want to consider using a waterproof mattress cover for added protection against future accidents.

Step 2: Blot Up Excess Liquid

Use paper towels or clean cloths to blot up as much urine as possible. Press down firmly to absorb the liquid, but avoid rubbing, as this can push the urine deeper into the foam.

The more liquid you can remove, the less work you’ll have to do later. If the accident happened in a larger area, consider using a wet/dry vacuum to extract as much urine as possible.

Step 3: Prepare the Enzyme Cleaner

Follow the instructions on your chosen enzyme cleaner to prepare it for use. This may involve diluting with water or spraying directly onto the affected area. Be sure to wear gloves if desired and avoid inhaling any fumes from the cleaner. Most importantly, the cleaner must be safe for use on foam mattresses.

Step 4: Apply the Vinegar Solution

Spray the Vinegar Solution

Spray the vinegar solution generously over the affected area. Ensure the mattress is damp but not soaking wet. Let the solution sit for 5-10 minutes to allow the vinegar to penetrate the foam and neutralize the urine. It’s important to note that vinegar has a strong smell, but this will dissipate as the mattress dries.

Step 5: Blot Again

After letting the vinegar solution sit, use paper towels or clean cloths to blot up the moisture. Repeat this process until the area feels only slightly damp to the touch.

This will help remove any remaining urine and vinegar solution from the mattress. You can also use a wet/dry vacuum to help speed up the process.

Step 6: Sprinkle Baking Soda

Generously sprinkle baking soda over the damp area. Baking soda is excellent for absorbing moisture and neutralizing odors. Allow the baking soda to sit on the mattress for several hours, or ideally overnight, to let it work its magic.

The longer it sits, the better. It’s also a good idea to sprinkle baking soda over the entire mattress for an extra freshening boost.

Step 7: Vacuum the Baking Soda

Once the baking soda has had ample time to absorb the moisture and odors, use a vacuum with an upholstery attachment to remove it; make sure to vacuum thoroughly, getting into all the nooks and crannies.

The baking soda should have absorbed any remaining moisture and odors, leaving your mattress fresh and clean.

Step 8: Apply Enzyme Cleaner

For persistent stains or odors, an enzyme cleaner can be particularly effective. Enzyme cleaners break down the proteins in urine, eliminating both the stain and the smell.

Spray the cleaner over the affected area and follow the manufacturer’s instructions for the best results. You may need to repeat the process if the stain or odor persists.

Step 9: Dry Completely

Hairdryer in a Cool Setting

Ensure the mattress is completely dry before putting any sheets back on. Use a fan or a hairdryer in a cool setting to speed up the drying process. Proper drying prevents mold and mildew from developing within the foam. It’s important to note that foam mattresses take longer to dry compared to traditional spring mattresses, so be patient.

Step 10: Freshen Up

Once the mattress is dry, sprinkle a light layer of baking soda over the entire surface and vacuum it up after 15 minutes.

This extra step ensures any residual odors are neutralized, leaving your mattress fresh and clean. You can also add a few drops of your favorite essential oil to the baking soda for a pleasant scent.

Following these steps on how to clean foam mattress after bedwetting regularly will help maintain a clean and hygienic foam mattress, ensuring it stays fresh and comfortable for years to come.

Additional Tips

Use a Waterproof Mattress Protector

Investing in a waterproof mattress protector can save you a lot of hassle in the long run. It acts as a barrier, preventing liquids from reaching the foam and making clean-up much simpler.

Rotate Your Mattress Regularly

Rotating Your Mattress Every Few Months

Rotating your mattress every few months can help it wear more evenly and reduce the likelihood of permanent indentations forming. This practice also helps ensure that any residual moisture evaporates more effectively.

Air Out Your Mattress

Whenever possible, allow your mattress to air out by removing all bedding and opening windows to let fresh air circulate. This practice helps eliminate lingering odors and keeps your sleep environment fresh.

Frequently Asked Questions

Q: How Often Should I Clean My Mattress?

A: Ideally, you should deep clean your mattress every six months. However, spot cleaning after any spills or accidents is crucial to maintain its longevity and hygiene.

Q: Can I Use Bleach on My Foam Mattress?

A: It’s best to avoid using bleach on a foam mattress, as it can damage the material and leave a strong, unpleasant odor. Stick to gentler cleaning agents like vinegar, baking soda, and enzyme cleaners.

Q: What If the Smell Persists?

Using an Odor-neutralizing Spray

A: If odors persist despite your best efforts, try repeating the cleaning process or consider using an odor-neutralizing spray specifically designed for mattresses.

In extreme cases, professional cleaning services may be necessary.  Remember, prevention is always better than cure.

Encourage frequent bathroom breaks before bedtime and consider limiting fluids a few hours before sleep to minimize the risk of future accidents. With proper care and maintenance, your foam mattress can continue providing you with restful sleep for years to come.
