A seemingly harmless habit can actually be fostering millions of mold spores! Recently, a housewife noticed that her freshly washed clothes often had a strange smell, and her skin became unusually itchy. Upon checking the washing machine, she discovered that the rubber gasket was covered in thick 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 that exceed the standard.

"Invisible Killer" in Your Washing Machine

• Damp Environment: A Perfect Breeding Ground for Mold: After washing, if you immediately close the washing machine door, the residual water inside the sealed compartment creates humidity levels over 90%. In these conditions, mold grows 20 times faster than in dry environments, and within just three days, a "mold colony" can form.

• Detergent Residue Promotes Bacteria Growth: Using too much detergent can leave behind sticky residues, which become an ideal food source for microorganisms, especially fabric softener, which can accumulate in the machine's hard-to-reach corners.

• Washing Underwear and Outerwear Together Causes Cross-Contamination: Fungi such as Trichophyton from socks or bacteria like E. coli from underwear can cause cross-contamination when washed together. Experiments have shown that the rate of bacterial cross-contamination when washing these items together can be as high as 45%.

Dangerous Habits to Avoid While Using the Washing Machine

1. Closing the Lid Immediately After Washing: This is a big mistake! After washing, you should leave the lid open for at least two hours to allow proper ventilation, and wipe down the drum's edges with a clean cloth. If your machine has a drying function, wait until it has completely cooled before closing the lid.

2. Not Cleaning the Detergent Drawer: The detergent drawer should be cleaned once a month. You can soak it in a solution of water and baking soda to dissolve any residue. Don’t forget to check the fabric softener tube to ensure it isn’t clogged.

3. Neglecting the Drain Filter: The drain filter, located at the lower right of the washing machine, should be cleaned every three months. You may be surprised to find small objects like coins, buttons, or even small toys in it.

Deep Cleaning Tips for Your Washing Machine

• Hot Water Cycle: Once a month, run a hot water cycle at 90°C (194°F). This temperature can kill 99% of harmful bacteria. If your machine doesn’t have a hot water setting, you can use 60°C water with white vinegar for a similar effect.

• Using Hydrogen Peroxide for Disinfection: Soak a towel in 3% hydrogen peroxide, then wipe down the rubber gasket, especially in the folds. Let it sit for 10 minutes, then wipe it again. This method is highly effective for stubborn mold.

• Regular Use of Specialized Cleaners: Choose a detergent that contains sodium percarbonate and use it once a month. Opt for a low-foam type to avoid damaging the machine's electronic components.

Good Habits to Maintain for Family Health

• Wash Underwear and Socks Separately: Use a dedicated laundry bag and wash them at a minimum temperature of 40°C (104°F). Those with sensitive skin should wash underwear by hand to avoid irritation.

• Remove Clothes Immediately After Washing: If clothes are left in the machine for more than an hour after washing, bacteria levels can rise again. Set a reminder on your phone to prevent forgetting.

• Regularly Check the Rubber Seals: If the rubber gasket is cracked or stiff, replace it immediately, as it is a breeding ground for bacteria. After cleaning, you can apply a small amount of baby powder (talcum powder) to prevent moisture buildup.

Research from the University of Tokyo shows that proper maintenance can reduce bacteria in washing machines by up to 86%.

Remembering these small details isn't just about being meticulous—it's about taking responsibility for your family's health. Start today by giving your "silent hero," the washing machine, a thorough cleaning. You'll notice a fresh, completely different scent on your clothes!
