Removing milk: pick your surface

Milk is a protein-based stain, usually from a knocked cereal bowl or a leaking bottle in a car or cot. The chemistry stays the same wherever it lands — but the safe way to treat it changes completely with the surface, which is why each pairing below has its own guide.

Water-soluble

Water-based cleaning can dissolve this stain — method and temperature are what matter.

Heat sets it

Keep hot water, steam and dryers away until the milk is fully out — heat fixes it permanently.

Fresh vs dried-in

Fresh milk blots out almost completely with cold water — the visible stain is the easy part. The trap is the residue: milk protein and fat left in the fibre sour within a day or two, and the smell arrives long after the mark has gone. Clean past the point where it looks finished.
