Check the mattress and identify the stain
Read the mattress care label and note whether the cover is removable. Identify what spilled and when, and record any previous products or treatments. If the material or substance is unknown, avoid experimenting.
Blot fresh liquid and limit moisture
Remove bedding and blot a fresh spill with an absorbent cloth, working gently without rubbing. Use water or a product only if the maker permits it, and avoid soaking the padding, applying heat or using a household mixture without approval.
Let the mattress dry fully
Follow the manufacturer's drying guidance and do not replace bedding until the area is completely dry. Do not use a heater, hair dryer or strong fragrance to cover remaining odour unless the maker specifically allows it.
Escalate extensive or concerning stains
Large spills, bodily fluids, persistent damp, mould-like growth or unknown contamination may require a specialist or mattress replacement. A domestic cleaner cannot diagnose health risks or guarantee stain removal.
