Exactly How Long Can You Leave Wet Laundry In the Washing Machine?

The struggle of forgetting laundry in the washing machine is one many have had to deal with, along with the musty mildew smell that accompanies day-old wash. Cleaning professionals say that laundry can be left in the washing machine for a maximum of 12 hours without risking mold and mildew. Anything over 12 hours will cause an unwanted odor to form, as well as bacterial mildew, both of which will require a new washing to remove. If you happen to go over the 12-hour limit, use half a cup of baking soda with your laundry detergent to get rid of the mold and mildew.
