How to Lubricate a Dishwasher Rack


Small bits of debris gather over time in the interior nooks and crannies of a dishwasher. They gunk up the wheels and track, causing the rack to stick and roll roughly. A periodic maintenance cleaning of the dishwasher should include lubricating the dishwasher rack.

Things You'll Need

  • Small, gentle brush
  • Non-toxic lubricant
  • Remove the top dishwasher rack by sliding the rack forwarding, then lifting up.

  • Scrub the track inside the dishwasher with a small, gentle brush to remove any build-up. Wipe the tracks with a mild detergent and a soft rag.

  • Take the dishwasher rack to the sink. Scrub the wheels with a small brush, removing any grime and debris. Turn the wheels by hand to remove any stuck fragments. Rinse the wheels with hot water in the sink.

  • Spray a non-toxic lubricant into the moving parts of the wheels, turning the wheels as you work in the oil. Some people choose a cooking spray for the lubricant. WD-40 also can be used on dishwasher wheels.

  • Replace the dishwasher rack, checking to make sure the wheels are rolling freely and smoothly.

  • Repeat with the lower dishwasher rack.

Tips & Warnings

  • You can use a toothbrush to scrub the tracks and wheels.
