Keep your waterproof bamboo cot sheets fresh without damaging the breathable membrane. This step-by-step guide shows you the safest way to wash, dry and care for them, so they stay soft, comfortable and leak-proof for longer. For an overview of which sheet to choose and sizing, see our Waterproof Baby Sheets Guide.
Before you start (safety & care)
Always follow your product’s care label. As a rule of thumb: use a gentle cycle, mild detergent, and avoid bleach, fabric softener and high heat—these can weaken the waterproof layer.
Detergents & care items
- Mild liquid detergent (enzyme or baby-safe)
- Cold or warm water
- (Optional) Baby-safe stain solution
Laundry gear
- Washing machine (gentle cycle)
- Laundry bag (optional)
- Clothesline or drying rack; low tumble if label permits
Step 1 - Check the care label
Confirm temperature limits and any special instructions for the waterproof membrane. Remove any mattress protectors or extra layers before washing.
Step 2 - Pre-treat small spots
Rinse spills promptly and dab stains with diluted detergent. Avoid harsh stain removers and never use bleach or fabric softener.
Step 3 - Wash on gentle
Place the sheet in the machine (laundry bag optional).
Select a gentle cycle with cold or warm water, add mild detergent, and run a full rinse. Do not overload, the sheet needs room to move.
Step 4 - Dry correctly
Line dry in shade to protect fibres and the membrane. If your care label allows, tumble dry on low. Avoid high heat, which can warp or delaminate waterproof layers.
Step 5 - Store flat and cool
Once fully dry, fold and store in a cool, dry place. Rotate sheets in use to extend lifespan.
Helpful tips
- For overnight leaks, keep a second sheet ready for fast swaps.
- Avoid fabric softeners, they can coat fibres and reduce breathability.
- If the membrane ever feels creased after drying, lay flat to relax before fitting.
Common mistakes to avoid
- High heat drying (can damage the waterproof layer).
- Bleach or harsh oxidisers (can weaken fibres and membrane).
- Skipping the rinse (detergent residue may irritate sensitive skin).
