How do I fix rust spot on dishwasher shelves?

You can buy a product made for this purpose, available at appliance stores, home stores, Amazon. Do a search for "dishwasher rack coating."

Step 1

Sand any rust spots off your dishwasher rack as soon as you notice them. You may use fine sandpaper to do this with, and finish it off with steel wool.

Step 2

Use a rust neutralizer or converter product to keep the rust from spreading any further. Rust neutralizers usually contain phosphoric or tannic acid, which halt the corrosive process so the metal part can be painted over.

Step 3

Buy a bottle of dishwasher rack touch-up paint from a hardware store or online. This vinyl paint usually comes in a small bottle and can be painted on like nail polish--a little goes a long way, and different colors are available so you should be able to find one to match your rack.

Step 4

Replace any rusted tines with rubber repair tips. These are often sold in kits along with the rack touch-up paint, and also come in different colors to match the paint scheme.
