Pro tip: For heavy tarnish, use a paste of lemon juice and salt, then rinse and dry.
8. Delicate Glassware (Etches and Breaks)
Why it’s bad: The high heat and harsh detergents can etch delicate glass (especially hand-blown or antique). The water pressure and jostling can cause chipping and breakage.
The damage: Cloudy film, rough texture, chips, cracks, or complete breakage.
What to do instead: Wash delicate glassware by hand with warm water and a mild detergent. Use a soft cloth or sponge. Rinse with cool water. Dry with a soft, lint-free towel.
Pro tip: Place a towel in the bottom of the sink to cushion glassware. Never stack glasses while washing.
Bonus: The Dishwasher Itself (What Not to Do)
Don’t overload the dishwasher. Overloading prevents water and detergent from circulating properly, leading to poor cleaning and potential damage to items.
Don’t use too much detergent. Excess detergent leaves residue on dishes and can etch glassware.
