Quick answer
Wash your cot waterproof mattress protector every two weeks using a gentle cycle and mild detergent, then air dry or tumble dry on low to preserve its waterproof layer.
Why regular cleaning matters
A clean mattress protector prevents dust mites, bacteria, and odors from building up. Since babies spend many hours sleeping, a fresh protector also reduces the risk of skin irritation and ensures the waterproof barrier stays effective.
Choosing the right detergent
Use a mild, fragrance-free liquid detergent. Harsh chemicals, bleach, or fabric softeners can damage the waterproof coating and reduce breathability. If your baby has sensitive skin, look for hypoallergenic options.
Step-by-step cleaning process
- Remove and inspect: Take the protector off the mattress. Check for any stains or residue. Pre-treat spots with a small amount of mild detergent and cold water, then let it sit for 5 minutes. Don't rub stains hard—blot them gently to avoid damaging the waterproof layer.
- Machine wash on gentle cycle: Place the protector in the washing machine. Use cold or warm water (not hot) on a gentle cycle. Add a small amount of mild liquid detergent—never use bleach or fabric softener. Hot water can break down the waterproof membrane over time.
- Rinse thoroughly: Run an extra rinse cycle to remove all detergent residue. Leftover soap can reduce breathability and cause irritation. Residue also attracts dirt faster, so a second rinse keeps the protector cleaner longer.
- Dry properly: Air dry the protector flat or hang it up. If using a dryer, choose the lowest heat setting and remove it while still slightly damp. Do not iron. High heat can melt the waterproof backing. Air drying is safest and preserves the fabric.
- Reassemble and rotate: Once completely dry, put the protector back on the mattress. Rotate or flip the mattress occasionally to distribute wear evenly. A second protector makes swapping easier and gives you time to wash without delay.
