It happens to all of us. We start a load of laundry, and then we get swept up in another household chore. Suddenly, it’s been two hours and our clothes are still sitting in the washer. Is this a problem?

Yes and no.

Obviously, you don’t want to leave your clothes in the washer for days on end. But a few hours probably won’t hurt them. If you’re able to get your clothes in the dryer within an 8-hour window, you’re probably in the clear.

Of course, there are a few exceptions that we will dive into so that you can make the best decision for your clothes and your washer.

If you’re unsure, it’s always best to err on the side of caution and take your clothes out of the washer sooner rather than later.

How Long Can You Leave Wet Clothes in the Washer?

The answer to this question depends on a few factors, such as the type of washer you have and the fabric of your clothing.

Let’s talk about fabrics. Natural fabrics like cotton can start to mildew if they sit in a wet environment for too long. This is because natural fibers are more absorbent than synthetic fibers.

So it’s best to get these wet clothes in a dryer as quickly as possible.

Thinner or synthetic fibers won’t retain as much moisture as other fabrics, so you can leave them in the washer for a little longer without worrying about mildew.

The cleaning agent you used to wash your clothes will also affect their longevity in the washer. If you use a bleach-based product, your clothes are more protected from odors and mildew.

However, if you’re using a natural laundry detergent, it’s best to take your clothes out of the washer sooner. This is because washing products don’t have the same bleaching agent that protects against mildew.

The weather environment will also play a role in how long you can leave your clothes in the washing machine. If it’s a humid or hot day, your clothes are more likely to mildew if they sit in the wet environment of the washer.

With all of these factors to consider, it may seem confusing to be able to tell how long you can leave wet clothes in the washing machine.

But in general, you should be able to leave your clothes for up to 8 hours without noticing any major changes such as a mildew smell.

What Happens if Wet Laundry Sits in the Washer Too Long?

If you leave wet clothes in the washer for an extended period of time, you’ll eventually be greeted by an unpleasant smell. This smell happens because damp clothes attract mold and mildew.

Mold and mildew are both types of fungi that thrive in moist environments. They can cause your clothes to rot and disintegrate over time and even stain them if not treated.

Not only is this a smelly problem, but it’s also a health hazard. Mold and mildew release spores into the air that can cause respiratory problems, trigger allergies, and aggravate asthma.

There isn’t an exact time frame for how long it takes for mold and mildew to start growing on your clothes. However, you’re more likely to see this problem if you leave your wet clothes in the washer for more than twelve hours.

Can I Leave Clothes Soaking in the Washer Overnight?

Soaking clothes overnight is less likely to cause mold and mildew growth because the fabric isn’t exposed to air and will therefore take longer to attract mildew and mold.

If you’re using an antimicrobial cleaning agent such as a stain and odor remover, this will also help to prevent any growth while your clothes are soaking.

When pre-soaking your clothes in the washer overnight, make sure to tend to it first thing in the morning.

Not only will this prevent any unwanted odors, but it will make sure that your clothing isn’t disintegrating, especially if you’re using a heavy-duty cleaner.
