How to Clean and Care for Your Cot Bed Mattress Protector

Keep your cot bed mattress protector waterproof and fresh with a simple wash routine, correct fit, and size-specific care for 140x70 and 120x60 protectors.
Quick answer
Wash your cot bed mattress protector every two to four weeks on a gentle cycle, and spot-clean accidents as soon as they happen. Always check the care label first, and make sure the protector is completely dry before you put it back on the mattress.
Why the waterproof layer changes how you wash
A waterproof mattress protector has a thin barrier that keeps leaks from reaching the mattress. That barrier is what makes the protector useful, but it also means you cannot treat it like an ordinary sheet. High heat, harsh bleach, and rough washing can break down the waterproof layer or make it stiff, so the protector stops doing its main job.
- Skip fabric softener: it can coat the surface and reduce absorbency.
- Avoid bleach and strong stain removers unless the care label says otherwise.
- Do not wring or twist the protector; handle it gently to protect the barrier.
Match the care routine to the size and fit
The two common cot bed sizes need slightly different handling because the elastic fit changes how the protector sits in the wash and on the mattress. A 140x70 protector has more fabric to move around, while a 120x60 protector is smaller and can bunch up more easily if overloaded. In both cases, fasten the elastic corners before washing to stop the protector from tangling with other items.
Step-by-step care routine
- Check the care label: Before washing, read the label on your Mokee cot bed mattress protector for the recommended temperature and drying method. If the label is missing, use a cool or warm gentle cycle and air-dry. Never guess the temperature; the label protects the waterproof layer.
- Remove and spot-clean fresh accidents: Take the protector off the mattress and rinse any soiled area with cool water as soon as possible. Avoid scrubbing hard, which can damage the waterproof coating. Treat stains before washing so they do not set in.
- Fasten the elastic corners: Hook the elastic corners together or tuck them in before washing to stop the protector from wrapping around other laundry. This is especially helpful for the larger 140x70 size. A tangled protector may not rinse clean or may stretch out of shape.
- Wash on a gentle cycle: Use a mild detergent and a gentle cycle with cool or warm water. Do not overload the machine; wash the protector with a few similar items so it can move freely. Overloading causes creases and uneven cleaning.
- Rinse thoroughly: Make sure all detergent is rinsed away. Residue can make the fabric stiff and reduce the protector's ability to stay comfortable against your child's skin. An extra rinse cycle is safer than using too much detergent.
- Air-dry or tumble on low: Hang the protector to air-dry or use a low tumble setting if the label allows. High heat can damage the waterproof backing, so never use a hot dryer setting. The protector must be completely dry before it goes back on the mattress.
- Refit and check the fit: Once dry, stretch the elastic corners over the mattress and smooth out any wrinkles. Check that the protector lies flat and does not bunch under the sheet, especially on a 120x60 cot bed. A loose protector can shift during sleep and leave the mattress exposed.
