Keeping dishes clean is an everyday chore, but should you wash dishes by hand or let your dishwasher do the work? Each method has its pros and cons for hygiene, water use, cost, and convenience.
Let’s dive into the details to help you decide the best option for your family’s needs and environmental impact.
The Hygiene Debate: Which Cleans Better?
1. Hot Water Matters for Killing Germs
When it comes to getting rid of bacteria and germs, dishwashers take the lead. Dishwashers use hotter water than what most people can tolerate for handwashing, with temperatures often reaching up to 150°F (65°C). This super-hot water kills more bacteria, ensuring your dishes are sanitized effectively.
The high temperature of dishwasher water is more effective at killing harmful bacteria,” says Jessica Ek, senior director at the American Cleaning Institute.
2. Are Dish Sponges Safe?
Handwashing often uses sponges, rags, or towels. They can harbour germs if not cleaned properly. Studies show they can breed harmful bacteria, like E. coli and Salmonella. They can harm humans.
It’s a common mistake to keep using the same sponge. They’re full of bacteria after just a few uses!” — Home Cleaning Expert
3. Handwashing Can Boost Immunity (Especially for Kids)
Interestingly, there’s some evidence that a bit of exposure to germs can help boost immune systems. This is especially true for families with young children. Kids exposed to small amounts of harmless bacteria from handwashing are less likely to develop allergies and have stronger immune responses as they grow up.
Environmental Impact: Dishwasher vs. Handwashing
1. Water Conservation with Dishwashers
Did you know that using a dishwasher conserves water? On average, a modern dishwasher uses only 7 litres of water per load, compared to 50 litres for the same number of dishes washed by hand. This makes dishwashers far more water-efficient than running the faucet for handwashing.
Using a dishwasher can save up to 5,000 gallons of water per year in the average household,” notes Alvin Pullins, home improvement specialist.
2. Energy Efficiency and Cost Savings
If your dishwasher is Energy Star certified, it’s designed to use less energy and water compared to handwashing. While dishwashers cost more upfront, they save on electricity and water bills over time. Many dishwashers recycle hot water, making them environmentally friendly and cost-effective in the long run.
3. Are There Downsides to Dishwashers?
Running a half-empty dishwasher wastes water and electricity, so it’s best to wait until it’s full. Additionally, dishwashers come with an upfront cost and require some space in the kitchen, which might be a factor in smaller households.
Health Considerations: Skin Protection and Safety
1. Protect Your Skin from Hot Water
Washing dishes by hand exposes your skin to scalding water and harsh dish soaps, which can irritate skin over time. If you’re determined to wash by hand, wearing rubber gloves is a smart choice to protect your hands.
2. Dishwasher Safety for Sensitive Skin
For those with skin sensitivities or allergies, dishwashers are often the safer choice, as they keep you away from hot water and strong detergents that can lead to dryness and irritation.
People with eczema or sensitive skin should be careful with handwashing dishes. Rubber gloves are a must,” recommends dermatologist Dr. M. Johnson.
Practical Considerations: Pros and Cons of Each Method
The Pros of Using a Dishwasher
- Saves Water and Energy: Uses far less water than handwashing and is energy-efficient.
- Sanitizes Better: Hot water kills more bacteria, keeping your dishes super clean.
- Convenient for Large Loads: Ideal for families who generate a lot of dishes daily.
The Cons of Using a Dishwasher
- Upfront Cost: Buying a dishwasher is more expensive than a bottle of dish soap.
- Requires Full Loads for Efficiency: Running a dishwasher half-empty wastes resources.
- Some Items Aren’t Dishwasher Safe: Not suitable for items like cast iron, wooden utensils, and fine china.
The Pros of Handwashing Dishes
- Best for Fragile and Special Items: Great for delicate dishes like crystal, fine china, and wooden utensils.
- No Initial Investment: You just need a sink, soap, and water.
- Quick for Small Loads: Efficient for washing a few items instead of a full load.
The Cons of Handwashing Dishes
- Higher Water Usage: Can use up to 50 litres of water per load if not careful.
- Irritates Skin: Constant exposure to hot water and soap can dry out hands.
- Not as Sanitary: Lower water temperatures make it less effective at killing germs.
FAQ: Frequently Asked Questions
Is It More Hygienic to Wash Dishes by Hand or in a Dishwasher?
A dishwasher is usually more hygienic. It uses hot water that kills bacteria better than handwashing.
How Much Water Does a Dishwasher Use Compared to Handwashing?

Which Is Better for the Environment: Dishwasher or Handwashing?
A modern dishwasher is better for the environment. It uses less water and energy, reducing your carbon footprint.
Can Handwashing Boost the Immune System?
Some researchers believe that bacteria from handwashing may help a child’s immune system. But, researchers need to conduct more studies.
Final Verdict: Which Should You Choose?
Choosing between handwashing and using a dishwasher depends on your priorities. If sanitization, water conservation, and convenience are top concerns, a dishwasher is the clear winner. For special or fragile items and one-off quick cleans, handwashing might be the better choice.
