Are dishwasher deodorizers safe to use?

While dishwasher deodorizers are safe to use, some of the chemicals that make up commercially available deodorizers could have negative health effects. A dishwasher can also be deodorized by using common household items, such as vinegar or baking soda, as they can remove bacteria that create foul odor.

A dishwasher needs to be deodorized regularly to remove foul odors that are created by leftover particles of food and grease. The proper time to deodorize a dishwasher is when it starts to emit a musty smell. Removable items inside the dishwasher, such as a glass guard or utensil holder, should be washed thoroughly in hot water before being deodorized.
