The Bottom Line If you've left clothes in the washing machine for over 12 hours, they probably need to be rewashed. If it has between 8-12 hours, give them a simple smell test, but they probably won't need to be rewashed. If it has been under 8 hours, you can just dry them straight away.
If your wet laundry has been sitting for under 12 hours and you're unsure whether it needs another wash, you can do a smell test of the items to see if there's a distinct mildew odour (a musty and often pungent smell). If not, it's safe to just hang them out to dry or pop them in the dryer.
Leaving wet clothes in the washer overnight can cause them to smell mildewy in the morning—but this doesn't always happen (and you might not have to run the load through another cycle).

According to home economist spokesperson from the Whirlpool Institute of Fabric Science, Lucinda Ottusch, 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 odour will form, and even more unlikely for bacterial mildew to develop.
Clothing that's only slightly whiffy can simply be air-dried. If you hang the item up outdoors, the breeze and fresh air will help remove the mildewy odour and save you the trouble of having to run another load. 2.
