How to Get Old Sweat Stains Out of Stored Clothes
Clothes pulled from storage can have yellowed underarm stains and a lingering sour smell because sweat and body oils left in the fabric oxidized over months into set-in stains and odor. Pre-treat the stains, soak, and wash right, and most of it comes out.
We make small-batch beeswax candles in Far Rockaway, so a room that truly smells clean is our whole focus, and that always starts at the source rather than the scent. Below is where the smell comes from, how to clear it step by step, and how to keep the space fresh afterward, with the full the MBur beeswax candle collection here as you read.
Why stored clothes develop stains and smell
Sweat and deodorant residue left in clothes, especially items stored without a thorough wash, oxidize over time, turning yellow and developing a stale smell. The longer they are stored, the more set-in it gets.
Heat sets it further, so it needs targeted treatment rather than just a normal wash. Breaking the oxidized stain down is what clears both the mark and the odor.
How to remove it, step by step
- Pre-treat the stains. Apply a paste of baking soda and water, or hydrogen peroxide with baking soda and a little dish soap, to yellowed areas and let it sit thirty to sixty minutes.
- Soak in an oxygen cleaner. Soak the garment in an oxygen-bleach solution, checking the fabric first, for a few hours to break down oxidized stains and odor.
- Wash with a booster. Wash with detergent plus a cup of white vinegar or a scoop of baking soda, in the warmest water the fabric allows.
- Skip the dryer until it is gone. Air-dry and check, since heat sets any remaining stain. Do not tumble-dry until the stain and smell are gone.
- Repeat if needed. Deeply oxidized stains may take a second treatment.
Keep it out of the dryer until the stain is fully gone. Dryer heat locks in oxidized sweat stains, so air-drying between treatments is what lets them come out.
Keep it from coming back
Wash clothes thoroughly before storing them, rather than putting worn or lightly worn items away, and store them clean and dry.
Treat sweat stains while they are fresh rather than letting them set over months.
Freshen the whole room once the source is gone
With the set-in stains handled, the air itself is the last step. A clean candle is the finishing touch here, best lit once the space is already clean. From there it is the fastest way to make the room read fresh rather than merely neutral.
For your home, Out of Office fits well. It is light and tropical, with spearmint, pineapple, and coconut, and like every MBur candle it is poured from 100% beeswax with a wooden wick and phthalate-free non-toxic fragrance oils, so freshening the air never means adding soot on top.
