The short answer

Cloudy glassware is a condition to identify, not a reason to switch products randomly. Mineral film, detergent residue, food soil, poor rinsing, water hardness, high heat, and permanent etching can look similar under kitchen lighting. Check whether the haze changes after an approved cleaning test and whether it appears across one load or every load.

Compare the clues

Clue Possible explanation What to record
Wipes or rinses away Film or residue Which approved method removed it.
Rough or permanently dull surface Etching Glass age, cycle heat, and repeated exposure.
White spots on all items Minerals or rinse issue Local water hardness and rinse-aid setting.
Residue in cups and corners Loading or detergent problem Dispenser, spray arm, and blocked surfaces.
Suds or odor Detergent or soil mismatch Product, amount, and cycle selected.

Inspect spray arms, filters, dispenser opening, and loading without reaching into moving or hot parts. Do not mix cleaners. Photograph a representative glass before changing one variable at a time. If the dishwasher is not draining or leaves water in the tub, solve that mechanical problem separately from glass appearance.

Make the service or product change useful

Record detergent type, amount, rinse-aid setting, cycle, water temperature if known, and load pattern. A service provider should distinguish a machine fault from water chemistry or glass damage. Replacing a pump will not reverse etching; changing detergent will not repair a blocked spray arm.
