Washing dishes is a daily chore in every household, but certain mistakes not only double the workload but also multiply bacteria by up to 70,000 times. This cross-contamination with toxins means these bacteria and toxins end up directly in your stomach by the next meal.
You may have been doing these mistakes for years without realizing it... See how many of these 5 bad habits you've fallen into.
Mistake #1: Stacking dishes after meals
Piling greasy dishes together only causes cross-contamination, doubling your washing workload!
Correct approach:
After meals, sort dishes into categories: separate non-greasy from greasy items. Wash non-greasy dishes first, then tackle the greasy ones.Additionally, bowls used for raw meat should be kept separate from those used for cooked food, fruits, and vegetables. Wash the cooked food bowls first, then the raw meat bowls.
Bad Habit #2: Soaking dishes for extended periods
Especially in summer, leaving dishes until the next meal allows food residue to ferment, creating unpleasant odors.
Experiments have shown that when 1-5 grams of meat, fish, rice, or vegetables are placed in bowls filled with water and left at room temperature for 10 hours, the number of staphylococcus and E. coli bacteria in the bowls can naturally increase to 70,000 times the original amount!
Once dishes harbor comparable bacterial loads, even scrubbing with sponges and detergent leaves residual pathogens.
Correct Approach:
Wash dishes immediately after meals while moisture remains. Clean pans right after cooking—add warm water while the bottom is still warm to easily rinse off grease.
Note: For non-stick pans, avoid immediately rinsing hot pans with large amounts of cold water, as thermal expansion and contraction can damage the surface coating.
Mistake 3: Using Dish Detergent Every Meal
While dish detergent has been a lifesaver, the habit of using it for every meal is highly inadvisable.
According to China Jiangsu Net, Zheng Mingfeng, Chief Physician of Thoracic Surgery at Nanjing People's Hospital and a long-time lung cancer specialist, has not used dish soap for years, opting instead for hot water.
When reporters interviewed three doctors from different hospitals, all coincidentally confirmed they use hot water rather than dish soap at home."Even if dishes are extremely greasy, I'd rather scrub them vigorously with hot water and a cloth than use dish soap," one doctor stated.
Correct Method:
Wash dishes with hot water and rice water or a small amount of flour for a gentle, eco-friendly approach. Hot water reduces grease viscosity, making it easier to rinse away; starch in rice water or flour solution binds with grease to eliminate stickiness.
For heavily greasy dishes, use baking soda dissolved in hot water. However, baking soda can irritate skin, so wear gloves when handling. If dish soap is absolutely necessary, rinse thoroughly multiple times. Chemicals are highly water-soluble and wash off easily.
Mistake 4: Drying dishes after washing them
A survey on household kitchen hygiene conducted by the Chinese Preventive Medicine Association found that dishcloths in Chinese homes harbor high levels of bacteria, including 19 types of pathogens such as E. coli, Staphylococcus aureus, Candida albicans, and Salmonella.
Test results from Beijing and Shanghai revealed that a single dishcloth could harbor up to approximately 500 billion bacteria!
With dishcloths this dirty, drying dishes with them after washing is essentially pointless. Microorganisms on the cloth may contaminate utensils and enter the body, potentially causing related illnesses.
Correct practice:
Dishcloths must be designated for specific uses. Ideally, separate cloths should be used for washing dishes, cleaning pots, wiping stove tops and range hoods, and cleaning dining surfaces. Additionally, wash dishcloths twice weekly with hot water and disinfectant, and replace them regularly.
Mistake 5: Never disinfecting for family use
While disinfection cabinets are now common household appliances, many skip disinfecting dishes for family meals to save money, only using them when guests arrive.
Correct practice:
Disinfection cabinets typically have two compartments. Place undisinfected items in one compartment and disinfect them in batches once enough have accumulated. This approach avoids excessive waste.Alternatively, boil utensils in water for 2–5 minutes to sterilize them.
Disease enters through the mouth. A single poor dishwashing habit can expose you to countless bacteria—a thought that’s downright disgusting. From now on, avoid these five mistakes and remind your loved ones to do the same!
