What to Look for When Buying Dishwasher Cleaner

Type and Ease of Use

According to professional cleaner Katie Berry, the best products for cleaning your dishwasher depends on how you use them. Tablets and pods are more convenient as you can generally just toss them in without measuring (great for busy households!), but you can't adjust how much of their ingredients are used. Powders and liquids offer the flexibility of adjusting the amounts more easily.

With modern dishwashers, it's easy to use most, if not all, of the dishwasher cleaner types— however, new dishwashers also use less water, so occasionally powders and tablets don’t dissolve thoroughly as desired. Berry advises priming your dishwasher by running the kitchen tap’s hot water before starting the dishwasher cleaning load.


While scent is overall a matter of personal preference, Berry says, “I'm not a fan of scented products in general, since they often produce VOCs and other irritants, but most standard dishwasher cleaners contain them.” As a professional cleaner, she prefers to use fragrance-free and dye-free products. The natural citrus, lavender, and lemon scents used by some brands are also fresh-smelling and non-toxic.


For cleaning your dishwasher, look for ingredients that will get the appliance clean without a lot of extra fragrance and dyes. Antibacterial ingredients are always a plus, while alcohol and borax help to get things squeaky clean. To make sure you’re purchasing products with the safest ingredients, it’s wise to check the EPA Safer Choice program. Safer Choice is a pollution prevention program that lists products with safe ingredients in order to reduce, eliminate, and prevent pollution at its source–while making sure your household is safe from toxic pollutants.

  • How do you use a dishwasher cleaner?

    Each dishwasher cleaning product is different—follow the instructions on the product’s packaging for the best results. Most dishwasher cleaners are either placed directly in the dishwasher cavity or in the slot where you normally put detergent.

  • How does dishwasher cleaner work?

    Once exposed to heat and moisture during the dishwasher cycle, dishwasher cleaners break down grease and bacteria and eliminate odor. With the help of water that rinses through your appliance when running, the cleaner can get into hard-to-reach areas that you wouldn’t otherwise be able to get to.

  • How often should you use dishwasher cleaner?

    Use dishwasher cleaner about once a month to prevent bacteria buildup and to maintain your appliance’s efficiency.
