Washer Smells: What Works and What to Avoid
Washer Smells: What Works and What to Avoid
You open your washing machine and a musty smell hits you. Your clothes have been coming out smelling less than fresh too, and you can’t figure out why. The problem isn’t your detergent. It’s your washing machine. Mold, mildew, and detergent residue build up inside the machine, especially in front-loaders where water sits in the rubber seal and drum. The smell transfers to your clothes with every wash. Here’s what works to remove washer smells and what to avoid.
Washer smells are caused by mold, mildew, and detergent residue that build up inside the washing machine. The buildup is most common in front-loaders, where water sits in the rubber seal and drum between uses. The smell transfers to clothes during washing.
To remove washer smells, run a cleaning cycle with a dedicated cleaner like affresh, wipe the rubber seal and detergent dispenser, leave the door open between washes, and use the right amount of detergent. Don’t use too much detergent, don’t use cold water for all loads, and don’t leave wet clothes in the washer.
What Works
Run a cleaning cycle with affresh. affresh Washing Machine Cleaner is designed to remove odor-causing residue and buildup inside the washing machine. Place one tablet in the drum and run a cleaning cycle (or the hottest cycle) once a month.
Wipe the rubber seal. On front-loaders, the rubber seal around the door traps water, hair, and debris. Wipe it with a cloth every 2 to 4 weeks. Check for black spots (mold) and clean with a mixture of water and white vinegar.
Clean the detergent dispenser. Remove the detergent dispenser and soak it in warm water. Scrub with a toothbrush to remove residue. Replace it and run a rinse cycle.
Leave the door open between washes. After each wash, leave the door or lid open to let the drum dry between uses. This is the single most effective thing you can do to prevent washer smells.
Use the right amount of detergent. Excess detergent leaves residue that feeds mold and bacteria. Use 2 tablespoons of Tide Free and Gentle per load.
Run hot water loads. Hot water helps dissolve and flush away residue. Wash towels, bedding, and whites in hot water regularly.
Use white vinegar. Pour 2 cups of white vinegar into the drum and run a hot water cycle (no clothes). The vinegar kills mold and dissolves mineral deposits.
Clean the filter. Check and clean the washer filter every 6 months. A clogged filter traps debris and causes odors.
What to Avoid
Using too much detergent. Excess detergent leaves residue that feeds mold and bacteria. The lines on detergent caps are 3 to 5 times larger than needed. Use 2 tablespoons per load.
Using cold water for all loads. Cold water doesn’t dissolve detergent as well as warm or hot water. Use hot water for towels, bedding, and whites to help flush away residue.
Leaving wet clothes in the washer. Wet clothes sitting in the washer promote mold growth. Transfer to the dryer or a drying rack within 2 hours.
Closing the door between washes. Closing the door traps moisture inside the drum, which promotes mold. Leave the door open between washes.
Using fabric softener. Fabric softener leaves a waxy residue that can contribute to odors. Use white vinegar in the rinse cycle instead.
Ignoring the rubber seal. The rubber seal on front-loaders traps water, hair, and debris. If you don’t clean it, mold grows there and spreads to the drum.
Never cleaning the machine. Even if you use the right detergent and leave the door open, residue builds up over time. Clean your machine monthly.
