Stains
How to remove sweat stains
Sweat yellows collars and underarms when protein meets deodorant. Start cold, treat with enzyme soap or vinegar — not bleach as the first move.

SweatCotton
Sweat Stains on Cotton — How to Get Them Out
Sweat stains on cotton respond well to enzyme soap and baking soda, which break down the proteins and oils that cause yellowing. Cotton is durable enough to handle scrubbing and hot water, so you can treat both fresh and set-in stains aggressively. The key is to work on the stain before it oxidizes and turns yellow, but even old underarm stains can be lifted with the right combination of products.

Sweat Stains on Cotton Shirts — Get Them Out
Sweat stains on cotton shirts respond best to enzyme treatment followed by a baking-soda paste, because the yellowing comes from a mix of body oils, proteins, and aluminum in antiperspirant. Cotton is durable enough to handle scrubbing and peroxide, so you can attack both fresh and set-in underarm stains without worrying about damaging the weave.
SweatLinen
Sweat Stains on Linen — How to Get Them Out
Sweat stains on linen respond well to enzyme soap and baking soda because linen is sturdy enough to handle scrubbing and soaking without damage. Fresh sweat lifts easily, but yellowed underarm stains need a soak to break down the oils and salts. Linen dries fast, so you can treat and rewash the same day.
SweatMattress
Sweat Stains on a Mattress — How to Get Them Out
Sweat stains on a mattress respond well to a paste of baking soda, hydrogen peroxide, and dish soap, which lifts the discoloration and neutralizes odor without soaking the foam or springs. Because you can't throw a mattress in the washer, you'll work on the surface and let it air-dry completely before making the bed again.
SweatPolyester
Sweat Stains on Polyester — How to Get Them Out
Sweat stains on polyester respond well to enzyme soap and baking soda because polyester traps body oils and deodorant residue that turn yellow over time. Unlike natural fibers, polyester won't shrink or felt, so you can scrub and soak more aggressively. The key is breaking down the protein and oil buildup before washing.

Sweat Stains on Polyester — How to Get Them Out
Sweat stains on polyester shirts respond well to enzyme soap and white vinegar because polyester holds onto body oils and deodorant residue that trap odor and discoloration. Unlike natural fibers, polyester won't shrink or felt, so you can scrub more confidently—but it does need cooler water to prevent setting the stain permanently.
SweatSilk
Sweat Stains on Silk — How to Get Them Out
Sweat stains on silk require cold water and gentle treatment to avoid damaging the delicate protein fibers. Silk is especially vulnerable to alkaline products and heat, so you'll use Castile soap and white vinegar to lift the stain without weakening the fabric. Always test on a hidden seam first, and never wring or twist silk while it's wet.

How to Get Sweat Stains Out of Silk Shirts
Sweat stains come out of silk shirts with cold water and enzyme soap applied gently to avoid damaging the delicate fibers. Silk is protein-based, so never use hot water or harsh scrubbing—both will weaken the fabric and set the stain. Work quickly on fresh stains, and test any cleaner on an inside seam before you treat the visible mark.
SweatWool
Sweat Stains on Wool — How to Get Them Out
Sweat stains on wool require cold water and enzyme soap to lift the protein without shrinking or felting the fibers. Wool is delicate: hot water causes felting, and harsh scrubbing damages the scales on each fiber. Work gently, blot instead of rubbing, and never wring or twist the fabric.
