Cloudy glasses? The spray arm holes are blocked
How to clean dishwasher spray arms
Spray arms clog with seeds, glass and limescale. Unclip them, poke the holes clear with a toothpick, rinse, and refit.
Switch off at the wall first. Watch for broken glass in the arm; wear gloves.
Never mix cleaning products. Bleach plus ammonia, vinegar or other acids releases toxic gases. Use one product at a time, rinse between them, ventilate, and unplug appliances before you clean them.
Step by step
- Remove the racks and unscrew or unclip the lower and upper spray arms
- Hold each arm under the tap and shake out debris
- Clear each hole with a toothpick or wooden skewer
- Soak in warm water with a splash of white vinegar for 15 minutes if crusted
- Refit and spin by hand to check they turn freely
