Bleach can severely damage your dishwasher if it has stainless steel parts, as chlorine is highly corrosive to metal and can cause pitting and permanent rust. It can also degrade the rubber door seals over time, leading to leaks.
Yes, you can use a little bleach to sanitize and remove mold from your dishwasher, but only if your appliance has a plastic tub. Never use chlorine bleach if your dishwasher has a stainless steel interior or stainless steel racks, as the bleach can corrode and permanently discolor the metal.
Choose vinegar for routine cleaning, calcium buildup removal, and deodorizing. Use bleach only for heavy mold and mildew, provided your dishwasher does not contain stainless steel parts (bleach can cause them to pit and rust). Never mix bleach and vinegar, as this creates toxic fumes.
Bleach and dish soap don't mix! Mixing chlorine bleach and cleaners like dish soap can be harmful to your health. Mixing bleach with other cleaners can release toxic gases. Bleach can irritate your skin and eyes.
No detergent is needed for this cleaning cycle. "Pour one cup of bleach into a dishwasher-safe, bleach-safe bowl and place it on the top rack of your dishwasher," she says. "Then run a full cycle but skip the drying cycle."
The best deep cleaners for your dishwasher are designed to target hard water, limescale, and stubborn grease. Top options include Affresh (highly recommended by major appliance brands), Glisten Dishwasher Magic (an EPA-registered disinfectant), and Cascade Platinum.
Yes, bleach can permanently ruin stainless steel. Its active ingredient, sodium hypochlorite, is a harsh chemical that breaks down the metal's protective chromium oxide layer. Stripping this layer leaves the surface vulnerable to permanent discoloration, dullness, pitting (small holes), and rust.
Using an Energy Star-certified dishwasher with a "sanitize" cycle is the most sanitary way to wash dishes, as it uses high water temperatures (150∘𝐹+) to kill bacteria, which is more effective than hand washing. For hand washing, the best method is scrubbing in hot soapy water followed by air-drying or soaking in a bleach-water solution.
Never add bleach to your main detergent dispenser. Instead, pour 111 cup of bleach into a bleach-safe bowl and place it upright on the top rack of an empty dishwasher. Run a full, hot-water cycle and skip the heated dry. Warning: Never use bleach if your dishwasher contains stainless steel, as it will cause corrosion and discoloration.
Yes, many restaurants use chlorine bleach (or similar chemical sanitizers) to sanitize dishes. For hand-washing, local health codes usually require a three-step process: wash, rinse, and sanitize. The sanitizing step often involves a heavily diluted chlorine bleach and water solution.
Never pour bleach directly into your dishwasher. It can corrode stainless steel, degrade rubber seals, and damage internal parts. Bleach also easily interacts with dishwasher detergents or residual vinegar to create toxic gases.
Using dish soap in a dishwasher creates a thick, sudsy foam in the appliance that can overflow through the dishwasher door. This is due to the formula of dish soap that relies on suds and bubbles to clean dishes. On the other hand, dishwasher detergent relies mostly on enzymes to get your dishes clean.
How to Sanitize a Dishwasher With Bleach
The most effective method to clean a dishwasher is to combine a manual scrub of the filter and door seals with a vinegar and baking soda wash cycle. This breaks down grease, deodorizes, and clears mineral buildup.
Add liquid chlorine bleach directly to the washer’s bleach dispenser before starting the cycle. If your machine doesn't have a dispenser, dilute 13one-third13 to 12one-half12 cup of bleach in a quart of water and add it 5 minutes after the wash cycle begins, or add it to the wash water before putting in your clothes.
Putting bleach in your dishwasher is generally a bad idea and should be avoided for regular use. While it is sometimes used for deep-cleaning or mold removal, it can easily damage the machine and your dishware.
Pour 2 cups (500 mL) of white vinegar into a glass measuring cup or other dishwasher-safe container and place upright in the lower rack. Run a normal cycle with the heat dry option turned off to clean the inside of your dishwasher. Do not use detergent.
Yes, you can use bleach to clean and sanitize your dishwasher, but never with dishes inside. It is only meant for cleaning the empty machine itself to kill mold and mildew.
Vinegar acts as a natural cleaner, deodorizer, and rinse aid in your dishwasher. Its acidic properties break down grease, soap scum, and hard water minerals, leaving your machine fresh and your glassware spotless.
Did you know your dishwasher moonlights as a cost- saving superhero? Running it at night can save money! Electricity rates are often lower during off-peak hours, so let your dishwasher pull the night shift and tackle those dishes while you catch some z's.
Cleaning power
Dishwashing vs. hand washing cleanliness in terms of sanitization ultimately comes down to water temperature. Depending on the model and settings, dishwasher water can heat to over 155°F as it cleans dishes, which exceeds the USDA's recommended 140°F necessary for sanitizing.
Symptoms of sodium hypochlorite poisoning may include:
Use a microfiber or soft cloth when wiping down your appliances. Avoid cleaners that can damage steel and finishes. Instead, clean your stainless steel appliances with a dish soap like Dawn® Platinum.
Pitting corrosion has been reported from household bleach spills on stainless steel, (304 type), sinks in domestic environments. If this occurs immediate dilution by rinsing should avoid pitting, but if left overnight, pitting can result.
