How to stop dishwasher racks from rusting?

 

Understanding Why Your Dishwasher Racks Rust

 

Dishwasher racks are generally made of metal coated with a vinyl or plastic material, serving to protect the metal from water and detergents. Over time, however, wear and tear may compromise this coating, exposing the metal underneath. When metal surfaces become exposed, they start oxidizing—leading inevitably to rust formation. Rust not only looks unsightly but can also stain dishes and utensils.

 

Inspect Dishwasher Racks Regularly

 

It's important to periodically inspect dishwasher racks carefully for any signs of damage or deterioration. Look closely for cracks, chips, or peeling coating as these areas are prone to rust. Catching small issues early can significantly extend the life of your dishwasher racks.

 

Thoroughly Clean and Dry Dishwasher Regularly

 

Keep dishwasher racks clean and dry as regularly as possible. Leftover food debris and moisture allow rust to form faster.

• After each wash cycle, open the dishwasher door partially to help moisture evaporate quickly.
• Every few weeks, clean racks thoroughly—removing grime and food particles from all crevices. This simple routine can eliminate buildup that accelerates corrosion.

 

Immediate Repair of Rack Damage

 

Once damage or cracks appear, swift action is essential to prevent rusting from worsening:

• Purchase a dishwasher rack repair kit specifically made for dishwasher racks—typically available at home improvement stores or online.
• Before repairing, use sandpaper or a wire brush to gently remove existing rust and loose coating around any damaged parts of the rack.
• Apply the specialized vinyl coating or paint included in the repair kit according to the manufacturers' instructions. Allow sufficient curing time.
• Regular inspections after repair help identify if the issue has been fully addressed or if more coating needs to be applied.

 

Protective Tips to Prevent Dishwasher Rack Rusting

 

• Consider using dishwasher-safe rack covers or plastic caps placed over metal prongs as a preventive measure. These small accessories help maintain the coating integrity of racks.
• Avoid using abrasive detergents and harsh cleaners that can degrade the protective plastic coating.
• Load utensils and dishes carefully, ensuring metal utensils or sharp-edged cookware don't scratch or chip dishwasher racks.

 

Water Quality and Rust Prevention

 

The quality of water running through dishwashers plays an important role in rust prevention. Hard water, common in areas like St. Louis and Nashville, may speed up corrosion due to mineral deposits.

• Consider installing a home water softener system to reduce mineral deposits and prevent corrosion of dishwasher racks.
• Alternatively, regularly inspect and clean mineral buildup from racks and other dishwasher parts with vinegar or specialized dishwasher cleaners made to handle hard water minerals effectively.

 

Professional Dishwasher Maintenance

 

If rust continuously reoccurs despite your efforts, consider seeking professional assistance to evaluate underlying issues causing persistent rusting. Professional technicians have access to advanced tools and expertise to restore your dishwasher racks and prolong their effective use. Ensuring professional maintenance periodically can significantly enhance the durability of your dishwasher racks, providing sustained convenience and protection.
