The plastic coating on dishwasher racks can wear off over time. To extend the life of your dishwasher rack:
- Snip off the end of the rusted tines with wire cutting pliers.
- Lightly sand the metal to remove any rust.
- Apply dishwasher rack coating (available at appliance stores) to the bare ends. To speed the process, turn the rack upside down, and dip each tine in the bottle of coating.
- Allow the plastic coating to dry at least 24 hours before using the dishwasher.
