Wash an IKEA GRUSNARV Waterproof Mattress Protector in Six Steps
After checking the GRUSNARV label, wash at up to 60°C, tumble-dry on low, and avoid bleach, ironing and dry cleaning. Protect the waterproof layer by separating items with zippers or buttons.
A waterproof mattress protector sits between the sheet and mattress; it is not the mattress itself. IKEA's GRUSNARV instructions (for example, 90 × 200 cm model 305.221.35) specify machine washing up to 60°C, low-temperature tumble drying up to 60°C, and no bleaching, ironing or dry cleaning. Verify the regional product code and sewn-in care label; do not generalise to other covers.
