How to Remove Mold and Mildew from Front-Load Washing Machines
Once your machine is clean, follow these tips to keep it that way:
Allow washer tub to dry.
Air It Out: If possible, leave the door of the front-load washer cracked open to allow it to dry thoroughly between cycles. However, you shouldn’t do this if you have children or pets who could be tempted to climb (and possibly become trapped) inside the machine.
Remove Loads Promptly: Be sure to remove wet clothes as soon as the cycle is finished. Set your washer to beep when it’s done, so you don’t forget.
Choose Detergent Wisely: Choose low-sudsing detergents specifically made for high-efficiency (HE) machines. When possible, choose powder over liquid; liquid detergents are usually higher in suds.
Clean washer dispensers.
Use Less Detergent: Read the labels and use no more than the amount recommended for each load. Experiment with using less detergent, until you find the minimum amount necessary (sometimes just a spoonful) to get your clothes clean.
Avoid Fabric Softener: Liquid fabric softeners leave residue that contributes to mold in front-load washers. Instead, use dryer sheets or dryer balls to soften your clothes.
Dry Gaskets: Use an old towel to wipe around and underneath the door gaskets and the inside of the door on front-loading washers. Ideally, you should so this after every cycle, but at the very least it needs a periodic wipe down to remove any water or mildew trapped in the folds.
Use Bleach: About once a month, run a hot water bleach cycle. I usually take the opportunity to throw in work towels, fabric shower curtains, and muddy gardening clothes, along with that nasty gasket-cleaning towel.
Occasionally use the Sanitize or Tub-Cleaning Cycle on front-load washers.
