  Do you often forget to close the washing machine door immediately after washing and rush off to do other things? This seemingly harmless action could actually be nurturing millions of mold spores! Recently, a housewife discovered that her freshly washed clothes often had a strange smell, and her skin started itching abnormally. Upon inspecting the washing machine, she found the rubber gasket covered in black mold. This is not an isolated case; according to a survey by the China Household Electrical Appliances Research Institute, more than 60% of washing machines in households across the country have mold levels exceeding the standard.

The "Invisible Killer" in the Washing Machine

• A damp environment is an ideal breeding ground for mold: If you immediately close the washing machine lid after washing, the remaining water inside the sealed compartment will create humidity over 90%. Under these conditions, mold grows 20 times faster than in dry environments, and in just 3 days, a "mold colony" can form.

• Detergent residues create a breeding ground for bacteria: Using too much detergent leaves residue behind, which serves as an ideal food source for microorganisms. Fabric softener especially accumulates in hard-to-reach corners of the washing drum.

• Washing underwear and outerwear together causes cross-contamination: Fungi such as red Trichophyton from socks, or bacteria like E. coli from underwear, can cause cross-contamination when washed together. Experiments show that the rate of bacterial cross-contamination when washing these items together can reach up to 45%.

3 Dangerous Habits When Using a Washing Machine

• Closing the lid right after washing: A big mistake! You should leave the lid open for at least 2 hours after washing and wipe the drum edges with a clean cloth. If your machine has a drying function, wait until the machine is completely cool before closing the lid.

• Not cleaning the detergent compartment: You should remove and clean the detergent tray once a month. You can soak it in a baking soda solution to dissolve the residues. Don’t forget to check if the fabric softener tube is clogged.

• Neglecting the drainage filter: The drain valve, located at the bottom right of the washing machine, should be cleaned every 3 months. You’d be surprised what you can find in there—coins, buttons, and even small toys.

Deep Cleaning Methods for Your Washing Machine

• Hot water cycle is a must: Once a month, run a wash cycle at 90°C. This temperature can kill 99% of harmful bacteria. If your machine doesn't have this function, you can soak the drum with 60°C water mixed with white vinegar.

• Use hydrogen peroxide for deep disinfection: Soak a cloth in 3% hydrogen peroxide and wipe the rubber gasket, especially in the folds. Let it sit for 10 minutes before wiping again. This method is very effective for stubborn mold.

• Use specialized cleaning agents regularly: Choose one containing sodium percarbonate and use it once a month. Be sure to pick a low-foam type to avoid damaging the machine’s electronic circuits.

Habits to Maintain for Protecting Your Family's Health

• Wash underwear and socks separately: Use a specialized laundry bag and set the water temperature to at least 40°C. People with sensitive skin should hand wash their underwear to avoid irritation.

• Remove clothes from the machine immediately after washing: Wet clothes left in the machine for more than an hour will see bacteria levels increase again. Set a phone reminder so you don't forget.

• Regularly inspect the rubber parts: If the rubber gasket is cracked or stiff, it must be replaced immediately, as this is where bacteria accumulate. After drying, you can apply a little talcum powder to prevent moisture.

A study from the University of Tokyo (Japan) shows that proper maintenance can reduce bacteria in washing machines by 86%.

Remembering these small details isn’t making a mountain out of a molehill; it’s a responsibility towards your family’s health. Starting today, give your “silent cleaning hero” in the house—the washing machine—a thorough cleaning. You will notice a completely fresh scent on your clothes!
