How to Deep Clean Your Dishwasher for Sparkling Dishes Every Time

Dishwashers need periodic deep cleaning to prevent odors, residue and even mold, since dirty machines don’t wash as effectively. Experts recommend cleaning timelines that vary with usage: Vera Peterson suggests every two to four months, while Jelina Saliu—who uses her dishwasher daily—cleans once a month. At minimum, the drain and filter should be addressed monthly. Signs it’s time include persistent smells and buildup, most often from a clogged drain filter. The process involves removing racks, scrubbing hot soapy water, cleaning the filter with hot soapy water or vinegar, and running two cycles—one with vinegar and one with baking soda—then wiping the exterior.
