They simply 'breed bacteria,' experts warn – 3 things you should never put in a laundry hamper
They cause more than just bad odors, experts warn


A laundry hamper is a catch-all for everything and anything that needs washing, right?
Not exactly. According to professional cleaners, tossing the wrong things into your laundry hamper can create unwanted odors, encourage bacteria, and even damage the rest of your garments and linens.
To save your clothes – and your hamper – these are the three things you should never put in a laundry hamper, and what you should do with them before doing laundry instead.
3 things you should never put in a laundry hamper
1. Damp towels
Letting towels dry between uses can prevent lingering musty smells.
One of the worst laundry mistakes ruining your clothing is putting damp towels straight into your laundry basket.
Alicia Sokolowski, cleaning and laundry expert and owner of AspenClean, explains, ‘Moisture trapped in towels creates the perfect environment for mold, mildew, and odor-causing bacteria to grow.
‘Within a few hours, the towel can develop a foul smell. Instead of throwing the damp towels into the hamper, hang them on a bar or hook to dry completely before tossing them in the hamper. Alternatively, if the towel has already been used numerous times, wash it right away.’
These decorative Command hooks, from Target, offer you a simple solution to hanging towels to dry in the bathroom between uses. They don’t require any drilling, so you don't need to fret about your DIY skills in tiled bathrooms.

2. Sweaty gym clothes and activewear
Leaving gym clothes to fester makes removing odors harder.
Getting the smell out of gym clothes is hard enough, but it is worse if they are allowed to sit and fester in a laundry hamper. For this reason, Alicia warns against putting them in a laundry basket.
She explains, ‘Synthetic fabrics like polyester and spandex, often found in sportswear, hold onto sweat and bacteria, which leads to strong odors and even bacterial growth if left balled up.’
Like towels, Alicia urges you to hang them up or spread them out to air dry before washing, or wash them immediately. ‘A quick rinse in cold water can also help if you can’t launder right away,’ she adds.
The same goes for any swimwear or swim towels, adds Matt O'Connor, co-founder and CEO at NoScrubs, adds, ‘Chlorine plus dampness damages other fabrics and breeds bacteria. Rinse and dry first.’
Using a dedicated activewear detergent, such as Persil ActiveWear Clean, from Walmart, can also help to tackle musty odors. Alternatively, to clean without harsh chemicals, opt for adding white vinegar to laundry.
3. Stained items
Stained clothing needs to be treated immediately to avoid permanent marks, or staining other items in a hamper.
The number one golden rule of stain removal is to treat the stains as soon as possible. That means anything with any type of stain should never go in a laundry hamper.
Scott Schrader, professional cleaner at CottageCare, says, ‘Items that have potential spills, including food, drinks, and bodily fluids, can breed bacteria very quickly. Before tossing them into the hamper, pre-rinse if you can, or spot clean and let dry.’
For quick stain treatment, consider the Miss Mouth’s Messy Eater Stain Remover Spray from Walmart. Verified shoppers love it, praising it for being ‘surprisingly powerful’, lifting all sorts of stains, including coffee and grease, without damaging fabrics.
What to shop

FAQs
How do you stop a laundry hamper from smelling?
Stopping a laundry hamper from smelling is simple, and can quickly stop a house from smelling musty, too, Scott advises, ‘The guiding principle is: You dry first, then you toss in the hamper. If you are not able to wash something immediately, give it airflow.
‘If you have a breathable mesh hamper [available at Amazon], it can help minimize the amount of moisture that gets trapped in your laundry; however, the prevention begins with not letting wet items pile up!’
