Routine cleaning of washing machines, refrigerators, and small appliances may prevent mold growth, bacterial spread, and indoor air issues.

Household appliances designed to simplify daily life may pose health risks if not properly maintained, according to housekeeping expert Mary-Ann Chen, who recently outlined common problem areas and practical cleaning strategies.
Chen warned that many appliances accumulate mold, bacteria, grease, and mineral buildup over time—often in areas not immediately visible—potentially contributing to skin irritation, food contamination, and reduced indoor air quality.
Washing machines, for example, can harbor mold along the outer rim of the inner drum. “During the drainage process, detergent and lint can cling to the outer wall, creating a favorable environment for mold and bacteria in warm, humid conditions,” Chen said. Indicators of contamination may include black marks on clothing or itching after laundering. She recommends deep-cleaning washing machines monthly at first, then every other month, using specialty cleaning products and leaving the door open after cycles to allow ventilation.
Refrigerators present additional concerns, particularly on door handles, shelves, and rubber seals. Door handles are frequently touched and can transmit germs. Moisture buildup inside the unit may harden on shelves, while temperature changes can encourage mold growth along door seals. Chen advises disinfecting handles regularly with alcohol, loosening hardened residue on shelves with a warm damp towel, and scrubbing moldy seals with a toothbrush and diluted bleach solution. She also recommends storing food in sealed containers and separating raw and cooked items to reduce cross-contamination.
Kitchen appliances exposed to heat and food residue can develop grease and mineral deposits. Ovens and air fryers often accumulate hardened grease along interior walls. Chen suggests placing detergent-soaked paper towels against greasy surfaces to soften buildup before wiping clean. Removable components should be disassembled and cleaned routinely.
Rice cookers commonly develop limescale—a white mineral residue—inside the heating chamber. Chen recommends filling the unit with water and two tablespoons of citric acid, bringing it to a boil, allowing it to soak, and then scrubbing. Microwaves can be deodorized and cleaned by heating citrus peels for approximately one minute to create steam that loosens grease. “Food should be covered when microwaved to prevent splattering,” Chen said.
Air quality may also be affected by neglected filters in dehumidifiers and air conditioners. Chen cautions against rinsing filters immediately, as water can push dust deeper into fibers. Instead, she recommends using a dry brush or vacuum first, then gently rinsing and air-drying away from direct sunlight.
Small kitchen appliances require attention as well. Coffee makers may accumulate dried oils and mineral buildup that affect taste. Consumer Reports advises washing removable components after each use and periodically running a cleaning cycle with equal parts water and distilled white vinegar. Blenders and food processors should be hand-washed promptly after use, with small brushes used to remove residue. Toaster and toaster oven crumb trays should be emptied regularly to reduce fire hazards and contamination risks.
Chen emphasized basic safety steps, including unplugging appliances before cleaning and consulting instruction manuals to avoid damage. She advised using dry cloths on appliance exteriors to prevent moisture infiltration and avoiding harsh chemicals that may degrade plastic components.
Experts note that routine maintenance—such as monthly cleaning of dishwashers and washing machines and annual dryer vent inspections—can help reduce mold growth, bacterial contamination, and fire risks.
Health specialists say that as households rely increasingly on modern appliances, consistent upkeep has become a critical part of maintaining a safe and sanitary home environment.
