If you let your wet clothes sit too long and notice they've developed an odor, you may have to deal with not only the mildew smell in your clothes, but also potential stains and patches of rotten fabric, says Bauer.
If you've ever wondered how long wet laundry can sit in the washer – and what to do about it – read on. The simple answer is 8-12 hours. That comes straight from the experts at Whirlpool, who make washing machines. Of course, the sooner you get them into the dryer the better.
If clothes are left in water, or even just damp, for too long, the dyes in the clothing can leak, fading darker colours and colouring lighter ones. In addition, dampness/wetness encourages the growth of mould and bacteria.
Leaving your clothes unattended for 24 hours is enough to build up mildew and moisture spots on your clothes. Mold is a white substance that develops on a garment sometime after it has mildew.
Prolonged exposure to moisture can weaken the fibers of your clothing, potentially causing them to deteriorate more quickly over time. To prevent these issues, it's best to remove your wet clothes from the washing machine promptly after the cycle is complete.
"That mold and that bacteria that starts to grow on damp clothes and environments, that's very pungent." Even if one item of the bunch smells, it's a good indicator that the entire load needs to be re-washed. For this reason, it's helpful to use a non-scented laundry detergent that's also free of harsh chemicals.
A good soaking is generally helpful for removing stubborn stains, but too long a soaking and your clothes will eventually fall apart. If you're using any kind of chemicals to wash clothes, follow the manufacturer's instructions for using them as incorrect use can cause a lot of damage.
Dirty or damp laundry provides nutrients for mold to grow, making it essential to thoroughly clean and dry clothes before storing them. Extended periods without washing or drying clothes increase the chances of mold infestation.
Leaving Wet Clothes in the Washer Can Cause Bacteria and Mildew to Grow. The biggest downside of leaving your clothes in the washing machine for more than eight to twelve hours is that, after this period, there's a greater chance that bacteria, mold, and mildew will grow.
Soaking clothes overnight can work well for really tough stains, but you don't always need to do it, and it can be a bit risky. For most stains, soaking for 4 to 6 hours should be enough.
If you choose to leave it out on the line for a couple of days through a series of rain showers, it is likely to develop a musty smell that will mean it needs rewashing.
One of the most prevalent New Year's superstitions is that on January 1 no washing should be done. However, some people go one step further and make it a custom to keep any dirty clothes unwashed from Christmas until New Year's Day.
Mildew loves damp places that don't get a lot of airflow, and it's capable of growing on any damp surface within just 24 to 48 hours. It can grow on clothes if you leave wet laundry in the washing machine for too long.
How long can you leave wet washing for? If damp clothes or bedding have been left in the washing machine or a basket for more than 8-12 hours we recommend giving it another wash. If it's been over 12 hours it's a safe bet that they will need to be re-washed.
A T-Shirt made from 100% cotton will decompose within a few months, and pure linen can biodegrade in as little as two weeks, while some natural fibers may take a bit longer. Depending on the blend, for example, wool may take between 1 and 5 years to decompose.
Choose the hottest setting on your washing machine. Most mold spores will die at temperatures above 140 degrees Fahrenheit (60 degrees Celsius), so cold and warm water cycles won't work. Add laundry detergent (regular detergent is fine). Add any other disinfectants, like vinegar, bleach or baking soda.
While placing garments in the dryer or on the clothesline right after the cycle finishes is best practice, wet laundry should generally not stay in the washer for more than 8-12 hours. Mildew and mold thrive in warm, damp environments, and the washer provides an ideal setting if laundry is left too long.
If you left clothes in the washer overnight, you may need to freshen them up before drying. A quick rewash may be all you need. Or, for a more thorough refresh of your laundry, run the same load on another full cycle and try adding a presoak option to help combat stubborn odors.
Bacteria can survive for weeks and, under some conditions, grow in stored laundry. You leave lots of good things for bacteria to eat in your clothing and cleaning tools, like washcloths. Reynolds: Germs survive better when they are surrounded by dirt, skin cells or bodily fluids – such as mucus and saliva.
Additionally, the wet conditions can increase the risk of infection and illness, as damp conditions can promote the growth of bacteria and other pathogens. Wearing wet clothing in cold temperatures can lead to a variety of health risks, including hypothermia, frostbite, chilblains, and immune system suppression.
After a day or two in warm conditions the clothes will start to mildew and smell funky, but you can still salvage them at that point if you rewash them with fresh detergent and an oxygen bleach. Left for a week in the bag they will reek and be permanently stained.
It may not be feasible to save the garment if the mold was allowed to grow for a long time. With the right approach, mold can be removed from clothing. The moldy clothing should be taken outside, cleaned of any visible mold, soaked in vinegar, washed in hot water with a high-efficiency detergent, and dried in the sun.
Mold and Mildew Growth
Clothes left sitting wet become susceptible to these fungi, especially when exposed for 12 to 24 hours. Despite appearing harmless, they cause a strong, musty smell, making your clothes unpleasant. Over time, if mold or mildew develops, it becomes more challenging to eliminate.
Lucinda Ottusch, a home economist spokesperson from the Whirlpool Institute of Fabric Science, has said that laundry can be left for up to 12 hours in the household appliance. Over an eight to 12 hour period it is unlikely an unwanted odor will form, and even more unlikely for bacterial mildew to develop.
Martha Stewart says leaving wet clothes overnight is “perfectly alright.” Martha's blog even says this can be a smart move if you're air drying the next morning—because sitting overnight helps get rid of excess water.
