Before starting the repair process, make sure your dishwasher is empty to avoid any interference with your work.

Step 2: Remove the Dish Rack

Use a screwdriver to carefully remove the dish rack from your dishwasher. If necessary, use needle-nose pliers to detach any clips or fasteners holding it in place.

Step 3: Clean the Rack

Clean the rack thoroughly with a mixture of warm water and rubbing alcohol. This will remove any grease, grime, or soap residue.

Once the rubber coating has dried completely, remove the masking tape, and reassemble the dish rack back into the dishwasher.

After reassembly, run a test cycle with your dishwasher to ensure the repaired rack is functioning correctly. Check for any signs of rust or damage.
