The cleaner and deodorizer relies on citric acid to naturally remove hard water buildup and debris from dishwashers. Free of bleach, ammonia, and formaldehyde, the powder formula is safe to use around kids and pets. In fact, it earned a Safer Choice certification from the U.S. Environmental Protection Agency in 2020. “Very simply, this stuff works,” a user wrote. “It turned a dull stainless-steel interior of an older dishwasher into a like-new interior. One application worked like a charm.” It even has a stamp of approval from appliance repair specialists, according to multiple reviewers with similar stories of discovering the product after calling a professional. “Recommended by the repair serviceman, this product does an outstanding job in clearing your dishwasher of hard water debris,” one person said.
