Bed wetting is a common occurrence, particularly in households with young children, elderly family members, or anyone dealing with certain medical conditions. Whilst it can be stressful, knowing how to clean a mattress after bed wetting quickly and thoroughly will help you protect your mattress, eliminate odours, and maintain a hygienic sleeping environment.
In this guide, we walk you through a practical, step-by-step approach to tackling urine stains and smells so your mattress stays fresh and clean for years to come.
Why It Is Important to Clean a Mattress After Bed Wetting Promptly
Acting fast is essential when dealing with a bed wetting incident. Urine that soaks into a mattress can cause several problems if left untreated:
- Bacterial growth: Warm, damp conditions inside a mattress create an ideal breeding ground for bacteria and other microorganisms.
- Persistent odours: As urine breaks down, it releases ammonia, which produces a strong and unpleasant smell that becomes harder to remove over time.
- Staining: Uric acid crystals bond with mattress fibres, leaving behind yellow or brown marks that set permanently if not addressed early.
- Mould and mildew: Excess moisture trapped within the mattress layers can encourage mould growth, which poses health risks including respiratory issues.
The soner you begin the cleaning process, the easier it will be to restore your mattress to a fresh and sanitary condition.
Step-by-Step Guide: How to Clean a Mattress After Bed Wetting
Step 1: Strip the Beding Immediately
Remove all sheets, mattress protectors, duvets, and pillowcases as soon as you discover the accident. Place them straight into the washing machine on a warm cycle with a biological detergent, which is effective at breaking down protein-based stains like urine. Adding a cup of white vinegar to the rinse cycle can help neutralise lingering odours in the fabric.
Step 2: Blot the Mattress
Using clean, dry towels or absorbent cloths, press firmly into the wet area to soak up as much moisture as possible. Work from the outside of the stain inward to prevent it from spreading further. Avoid rubbing or scrubbing at this stage, as this can push the urine deeper into the mattress layers.
Step 3: Apply a Vinegar Solution
Mix equal parts white vinegar and cold water in a spray bottle. Spray the solution generously over the affected area. White vinegar is a natural disinfectant that helps break down uric acid and neutralise odours without introducing harsh chemicals to your sleeping surface. Allow the solution to sit for 10 to 15 minutes before blotting again with fresh towels.
Step 4: Sprinkle Bicarbonate of Soda
Once you have blotted away the vinegar solution, cover the entire affected area with a generous layer of bicarbonate of soda (baking soda). This household staple is remarkably effective at absorbing residual moisture and drawing out odours from deep within the mattress. For best results, leave the bicarbonate of soda in place for at least eight hours, or ideally overnight.
Step 5: Vacuum Thoroughly
After the bicarbonate of soda has had time to work, vacuum the mattress surface using the upholstery attachment on your vacuum cleaner. Go over the area several times to ensure all the powder is removed. This step also helps lift any remaining dried residue from the mattress fibres.
Step 6: Check and Repeat if Necessary
Inspect the mattress for any remaining stains or odours. If traces persist, repeat the vinegar and bicarbonate of soda treatment. Stuborn or older stains may require two or three rounds of cleaning before they are fully eliminated.
Dealing with Dried or Old Urine Stains
If the bed wetting incident was not discovered immediately, dried urine stains require a slightly more intensive approach. Create a cleaning paste by combining the following:
- 3 tablespoons of bicarbonate of soda
- 1 tablespoon of liquid dish soap
- 1 tablespoon of hydrogen peroxide (3% concentration)
Apply the paste directly to the stained area and gently work it into the fabric using a soft cloth or an old toothbrush. Allow it to dry completely, then vacuum away the residue. Hydrogen peroxide acts as a mild bleaching agent, so it is advisable to test this mixture on a small, inconspicuous area of the mattress first to ensure it does not cause discolouration.
How to Remove Urine Smell from a Mattress
Even after visible stains have been removed, odours can linger. Here are some additional tips for eliminating urine smell from your mattress:
- Enzyme-based cleaners: These specialist products contain natural enzymes that break down the proteins in urine at a molecular level. They are widely available from supermarkets and pet supply shops and are safe for use on most mattress types.
- Fresh air and sunlight: If possible, stand the mattress near an open window or in a well-ventilated room. Sunlight has natural antibacterial properties and can help dissipate odours effectively.
- Essential oils: Adding a few drops of lavender or tea tree oil to your bicarbonate of soda before sprinkling it on the mattress can leave a pleasant, fresh scent whilst also providing mild antibacterial benefits.
Preventing Future Bed Wetting Damage
Prevention is always better than cure. Taking a few simple precautions can save you considerable time and effort in the long run:
- Use a waterproof mattress protector: A quality waterproof protector creates a barrier between the sleper and the mattress, preventing urine from soaking through. Look for breathable, machine-washable options for maximum comfort and convenience.
- Layer your bedding: Place a waterproof pad beneath the fitted sheet for an extra layer of protection. Some parents find it helpful to layer two sets of sheets with waterproof pads in between, making middle-of-the-night changes quicker and easier.
- Establish a routine: For children who experience regular bed wetting, limiting fluid intake before bedtime and encouraging a trip to the toilet just before sleep can help reduce incidents.
When to Consider Professional Mattress Cleaning
Whilst home cleaning methods are effective for occasional accidents, there are situations where professional intervention is the best course of action. If your mattress has experienced repeated bed wetting incidents, deep-set stains, or persistent odours that home remedies cannot resolve, a professional cleaning service can make a significant difference.
Professional mattress cleaning uses industrial-grade equipment and specialist solutions that penetrate deep into the mattress core, removing bacteria, allergens, and stuborn stains that surface cleaning simply cannot reach. This is particularly important for households with allergy sufferers, young children, or anyone with compromised immune systems.
