How to Fix Dishwasher Rack Rust: Quick & Easy Solutions
To fix dishwasher rack rust, first remove rust with sandpaper. Next, apply dishwasher rack coating or touch-up paint. Let it dry completely. For prevention, add rack caps to exposed metal tips.
Assessing the Extent of Rust Damage

Initial Visual Inspection
Begin by pulling out your dishwasher rack and placing it in a well-lit area. Look over each section carefully, paying close attention to corners and weld points where rust often starts.
Look for signs of flaking or discoloration that suggest the protective coating has been compromised. This visual inspection is crucial to understanding how much work you’ll need to do.
Identifying Problem Areas
As you examine the rack, you might see spots where the plastic coating is chipped or cracked.
These are the areas most vulnerable to rust. Use a small piece of tape to mark each spot you find. This way, you won’t miss any areas when you start the repair process.
Evaluating Rust Severity
With all problem areas marked, determine the severity of the rust. Is it just on the surface or has it penetrated deeper into the metal?
Surface rust is easier to deal with, while deeper corrosion may require more extensive repair or even replacement of the affected parts.
Decision on Repair or Replace
Finally, decide whether it’s worth repairing the rack. If the rust is widespread, it might be more cost-effective to replace the rack entirely. However, if the damage is localized, a repair is likely the best option.
Preparing to Repair the Dishwasher Rack

Gathering Repair Supplies
Acquire the necessary tools and materials for the job. You will need fine-grit sandpaper, a wire brush, dishwasher rack repair kit or coating, gloves to protect your hands, and safety glasses to shield your eyes from rust particles.
Removing the Dishwasher Rack
Take out the dishwasher rack to gain full access to all sides for a thorough repair. Consult your dishwasher’s manual if you’re unsure how to remove it properly. With the rack out, you can work on it without the confines of the dishwasher’s interior.
Cleaning the Rack
Before you begin repairs, clean the rack with soapy water and a sponge to remove any grease, detergent residues, or food particles. Rinse it well and let it dry completely to ensure the repair materials adhere properly.
Repairing the Dishwasher Rack

Removing Rust from Affected Areas
Now it’s time to get to work. Put on your gloves and safety glasses, and use sandpaper or a wire brush to gently scrub away the rust.
Be thorough but cautious to avoid damaging the rack further. Once you’ve removed the rust, wipe down the area to clear away any debris.
Applying Repair Coating
With the rust removed, follow the instructions of your dishwasher rack repair kit. Typically, this involves applying a sealant or coating over the affected areas. Ensure you cover all the bare metal to prevent rust from returning.
Allowing Ample Drying Time
Once the coating is applied, it’s crucial to let it dry completely before reinstalling the rack. Rushing this step could result in the coating peeling off or not providing adequate protection against future rust.
Preventing Future Rust
Prevention is key to maintaining your dishwasher rack. Consider adding rack caps to exposed metal tips to protect them from wear and tear.
