Removing sweat: pick your surface
Sweat is a protein-based stain, usually from nightly contact on a mattress or regular contact on seating. 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 sweat is fully out — heat fixes it permanently.
Fresh vs dried-in
Sweat stains build gradually rather than arriving as a spill: salts, skin protein and body oils accumulate until a yellowed patch shows. The yellowing is partly a reaction with antiperspirant aluminium salts, which is why it concentrates where skin rests. Old marks need repeated enzyme treatment, not harder scrubbing.
