I. Immediate Emergency Treatment
First, remove all sheets and mattress pads and wash them.
Use dry towels, disposable bath towels, and absorbent paper towels to firmly press and absorb the urine. Do not rub back and forth, as this will spread the stain and allow the liquid to seep deeper into the mattress.
Continue to change the dry towels until the surface is mostly dry.
Remember: Do not immediately rinse with a large amount of water, as water can easily cause mold and rust on the springs inside the mattress.
II. Household Safe Cleaning Agent Formulas
Formula 1 (Highly Recommended, Decomposes Urine Protein, Removes Odor)
Hydrogen peroxide 3% : Baking soda : Dishwashing liquid = 250ml : 2 scoops : 1 teaspoon
Stir well and pour into a spray bottle.
Formula 2 (Simplified Version)
Warm water + a small amount of neutral laundry detergent; do not use strong alkalis or 84 disinfectant on latex mattresses.
III. Step-by-Step Stain Cleaning
Spray a thin layer of cleaner onto the stain, just enough to wet the surface, do not soak it;
Let it sit for 15-30 minutes to allow the liquid to decompose the urine;
Use a dry towel to press and absorb the dirty water again;
Damp a clean towel with clean water and press and wipe away any remaining cleaner, repeating 2-3 times.
IV. Thoroughly Remove Urine Odor (Crucial)
Dry Method with Baking Soda: After the stain has completely dried, sprinkle a thick layer of baking soda and let it sit for 4-8 hours (overnight is best). The baking soda will absorb the odor; then vacuum it clean.
Stubborn Odors: Use a special mattress deodorizing enzyme cleaner (the enzymes break down urine proteins, eliminating the odor completely).
Do not use cologne or perfume to mask the odor; these only provide temporary relief.
V. Drying
Open windows for ventilation, and lift the mattress to air it out from both sides.
Direct Sunlight: Move the mattress to the balcony to sunbathe, turning it over to air dry. Latex mattresses should only be aired in the shade; avoid direct sunlight, as this will cause them to age and crack.
Damp and Rainy Days: Use a hairdryer on the cool setting, or a fan to blow air onto the mattress. If you have a dehumidifier, use the dehumidification mode on your air conditioner.
The mattress must be completely dry inside before laying it on the bed; otherwise, it will definitely mold and yellow.
VI. Precautions for Different Mattresses
Spring/Coconut Fiber Mattress: Minimize water spraying, as coconut fiber absorbs water easily and is prone to mold. Prioritize pressing to absorb water + using bio-enzymes + ventilation;
Latex Mattress: Strictly avoid direct sunlight, hot water, bleach, and excessive spraying with alcohol. Use only mild detergent and air dry in the shade;
Memory Foam Mattress: Difficult to dry completely after absorbing water. Clean sparingly and dry with a fan for an extended period;
VII. Post-Bedwetting Prevention Tips
Use a waterproof fitted sheet. After bedwetting, only the fitted sheet needs to be washed; the mattress will not get dirty;
Children should drink less water before bed and go to the toilet before sleeping.
How to remove dried urine stains from a mattress?
The reason dried stains are so difficult to remove is that the uric acid salts in the urine have crystallized and seeped into the mattress fibers, making them difficult to clean with ordinary water. Use a bio-enzyme cleaner first; home-use formulas can also handle it. Below are general steps, homemade solutions, stubborn yellow stains, and precautions for different types of mattresses.
Preparation:
Remove all bedding;
Vacuum the surface of the stain;
Only wet the stained area with cleaning liquid; do not soak the entire mattress to avoid internal dampness and mold.
Method 1: Bio-enzyme cleaner is the best choice
The odor of urine is essentially urea protein, and enzymes can directly break down the protein, rather than masking the smell.
Dilute the solution according to the instructions and spray it onto the dried urine stain;
Let it sit for 30-60 minutes to allow the enzymes to fully penetrate the crystallized stain;
Press repeatedly with a damp towel, do not rub back and forth;
Press with a clean towel to remove any residue;
Dry with a fan for an extended period, then sprinkle with baking soda and let it sit overnight before vacuuming.
Method 2: Homemade Stain and Odor Remover Spray
Suitable for most spring and coir mattresses (use hydrogen peroxide with caution on latex mattresses)
Ratio: 250ml 3% medical-grade hydrogen peroxide + 2 teaspoons baking soda + 1 drop neutral detergent
Stir until mostly dissolved, then pour into a spray bottle;
Spray a small amount onto the stain, just enough to moisten it;
Let it sit for 30 minutes, the uric acid yellow stains will gradually fade;
Press with a dry towel to absorb the dirty water;
Rinse thoroughly with a clean, damp towel, pressing and pressing to remove any residue.
Tip: Hydrogen peroxide has a slight bleaching effect. For dark mattresses, test on a hidden corner first to prevent fading.
Method 3: Baking Soda + White Vinegar Combination
Suitable for strong odors and relatively shallow yellow stains.
Spray a layer of diluted white vinegar (white vinegar: warm water = 1:1) on the stain, let it sit for 15 minutes to neutralize uric acid;
Sprinkle a thick layer of baking soda on the surface, fully covering the stain;
Let it sit overnight for at least 8 hours;
Vacuum thoroughly to remove any powder;
Repeat the process 2-3 times for any remaining yellow stains.
Intensive Solution for Stubborn, Old Yellow Urine Stains
Hydrogen Peroxide Compress: Soak a paper towel in hydrogen peroxide, place it on the yellow stain, and apply as a compress for 20 minutes;
Remove the paper towel and press with a towel to absorb excess water;
Spray white vinegar to neutralize any residue;
Leave baking soda overnight to absorb odors;
Use a fan to dry the area for 24 hours, ensuring the mattress is completely dry.
Different Mattress Hardness Contraindications
Latex Mattresses: Do not use hydrogen peroxide, 84 disinfectant, alcohol, or expose to direct sunlight. Wipe with diluted neutral laundry detergent, then air dry in a cool, ventilated place; for stubborn odors, use bio-enzymes.
Coconut fiber mattresses: Coconut fiber absorbs water and easily molds, so use as little liquid as possible. Only spray to moisten the surface; do not rinse or soak.
Memory foam mattresses: They absorb water and are difficult to dry completely, so spray as little water as possible. After cleaning, use a hairdryer and dehumidify with an air conditioner for an extended period.
Absolutely Do Not Use:
Do not use 84 disinfectant: It will corrode the mattress fabric and springs, leaving a pungent odor;
Do not wash with hot water: High temperatures will cause uric acid protein to permanently solidify in the fibers;
Do not use perfumes or air fresheners to mask odors, as uric acid crystals will cause the odor to recur if not removed;
Do not put on sheets until the mattress is completely dry, as this will quickly breed mold and black spots.
Post-cleaning Prevention: After cleaning, immediately put on a waterproof fitted sheet. If it gets dirty again, simply wash the fitted sheet to protect the mattress.
How to dry a mattress after steam cleaning?
Steam cleaning allows moisture to penetrate the inner layers of the mattress. The key goal is to thoroughly dry the mattress, preventing mold, yellowing, urine odor, rusting springs, and rotting of the palm fiber mattress. Below are general steps, methods for different materials, speed-up tips, and things to avoid.
I. Immediately after steam cleaning
Remove all sheets, covers, and waterproof fitted sheets to completely expose the mattress. Take a large, dry towel and firmly press it onto the steam-treated area to absorb excess moisture. Do not rub or rub. Flip the mattress over and ventilate both sides alternately. If possible, lift the mattress upright to allow for side ventilation.
II. Regular air drying
Open windows for full ventilation and also open doors to create airflow. Spring mattresses: Can be placed in a shady spot on the balcony for ventilation; they can be sun-dried briefly in gentle sunlight. Latex, memory foam, and coconut fiber mattresses should not be exposed to direct sunlight. Excessive sunlight will cause latex to powder, memory foam to crack, and palm fiber mattresses to become brittle. They should only be air-dried in the shade. III. Quick Drying (Prioritized for Damp, Cloudy Days and Rainy Seasons)
1. Fan (Best Value)
Use 2-3 electric fans to continuously blow air onto the front, back, and sides of the mattress.
Elevate the mattress by supporting the four corners with a stool, leaving gaps at the bottom, as moisture is least likely to dry at the bottom.
2. Air Conditioner/Dehumidifier
Turn on dehumidification mode. Lowering the indoor humidity to below 50% will significantly accelerate moisture evaporation. In humid weather, simply blowing air without dehumidifying will make it difficult for the mattress to dry completely.
3. Hair Dryer – Use Only Cool Air
Strictly avoid hot air, as high temperatures will cause the mattress’s inner adhesive layer to age, the fabric to yellow, and the fixing glue to come unglued. Only use the cool air setting to blow on damp areas at close range.
IV. Drying Requirements for Different Mattresses
Independent Spring Mattresses: Can be sun-dried, flipped over for ventilation, and the bottom elevated. After steaming, moisture tends to trap in the spring gaps; ventilate for at least 24-48 hours. Latex Mattress: Absolutely expose to direct sunlight and hot air; lay flat or stand upright in a cool, well-ventilated location and use a fan on cool air for extended periods to dry, typically taking 1-2 days.
Coconut Fiber Mattress: Coconut fibers are highly absorbent and prone to mold after steaming; must be elevated with the bottom suspended, and used with a fan and dehumidifier for extended periods. If necessary, remove the outer fabric to ventilate the inner layers. Never put the mattress back on until completely dry.
Memory Foam Mattress: The material traps moisture, making it difficult for steam to escape; minimize steam cleaning; after washing, continue dehumidifying with a hairdryer for 2-3 days.
V. Odor Removal and Moisture Control Tips
Sprinkle a thick layer of baking soda on damp areas to absorb moisture and residual urine odor. Vacuum thoroughly after drying.
Do not immediately cover with bedding; the mattress is only truly dry when you feel a cool, damp sensation deep inside.
VI. Prohibited Practices
Do not use hot air to dry or expose to direct sunlight for extended periods (latex, coir, memory foam mattresses).
Do not close doors and windows tightly to allow moisture to build up, as trapped moisture will directly breed mold.
Do not lay out sheets, blankets, or waterproof mattress protectors until the mattress is completely dry.
Do not use a heater to dry the mattress, as this can damage the inner lining material and may even pose a fire hazard.
