Dishwasher racks are typically made of metal with a vinyl or plastic coating, although some are made of plastic or stainless steel. Over time, the coating on dishwasher racks can wear away, exposing the metal underneath to water and humidity, which causes rust. This rust can then stain or scratch dishes. To prevent this, the plastic coating can be repaired or replaced. This can be done using a dishwasher rack repair kit, which includes vinyl repair paint and replacement rack tips, or by gluing on dishwasher rack caps to cover rusted tines.

Repair kits for dishwasher rack recoating
Repair kits are available for recoating dishwasher racks to prevent rust and protect dishes from scratches. These kits typically contain liquid vinyl or paint that can be applied directly to the affected areas of the rack, repairing and restoring its protective coating.
One such product is Uber Goop™, which offers an "industrial-grade" liquid vinyl repair kit. The kit includes 25 caps, each containing 1/2 oz of liquid vinyl, which is enough to repair a standard dishwasher rack. Uber Goop™ is designed to be easy to apply, with a one-step applicator that can reach tight spots, ensuring all affected areas are properly coated. The fast-drying formula means your dishwasher can be used soon after application, with minimal downtime.
Another option is the ReRack kit, which can be purchased from Walmart, ACE Hardware, and other hardware stores. ReRack is available in a satin white rubber coating, and it is designed to be heat and rust-resistant. It is important to note that some users have suggested applying two coats of ReRack, as the first coat may be difficult to see if it matches the colour of your rack.
Additionally, some manufacturers offer special paint kits to repair minor rust issues. These kits can be purchased from the manufacturer or from stores that sell dishwashers. You can also try using products like Plasti Dip, available at Home Depot, or Rust-oleum's "Appliance Touch-Up," which comes in a small bottle similar to nail polish.
When using any of these repair kits, it is important to follow the instructions carefully and ensure proper ventilation during application.

Using vinyl repair paint
ReRack by Plasti Dip is a vinyl repair paint product that can be used to recoat plastic on dishwasher racks. It is a flexible, speciality rubber coating that exhibits excellent adhesion to dishwasher and other vinyl-coated racks. It can be applied using a brush-on formula or a spray.
Before applying ReRack, ensure that the surface is clean and free of any rust or corrosion. If necessary, use a Dremel to grind away any rust or corrosion. It is also important to shake the bottle vigorously to ensure that the product is well mixed and has a consistent thickness. Apply ReRack in thin, light coats, allowing sufficient drying time between each coat.
When using the brush-on formula, ensure that you apply the coating precisely to the worn or damaged areas of the dishwasher rack. The self-levelling properties of the product will provide a smooth and even finish, effectively covering imperfections.
When using the spray, hold the can at least 6 inches away from the surface and spray in a back-and-forth motion. Avoid spraying too much in one area, as this can cause dripping or sagging. If you experience runs or sags, move the can further away from the surface and apply a lighter coat.
It is important to note that ReRack has toxic vapours, so it is recommended to apply it outdoors or in a well-ventilated area. Additionally, the product may have a short shelf life once opened, so it is best to use it within a few months of purchase.

Removing rust with a wire brush
Dishwasher racks can sustain damage over time due to wear and tear from daily use, including washing heavy pots and pans, as well as high temperatures, moisture, and harsh detergents, which can cause rust and corrosion. This can lead to dishes becoming damaged and inefficient cleaning. To prevent this, racks can be repaired with vinyl repair paint and replacement rack tips, which are sold at appliance parts stores or online.
One way to repair a rusty dishwasher rack is by using a wire brush to remove the rust. Wire brushes are ideal for rust removal as they are unlikely to remove metal or change the surface profile. They are also non-loading, meaning they won't become clogged with material. To use a wire brush attachment effectively, avoid pressing too hard. This will ensure the necessary hammer action at the tips of the filaments.
There are different types of wire brushes available, including steel and stainless steel brushes. Steel brushes are suitable for use on ferrous metals (those containing iron), such as carbon steel, cast iron, and wrought iron. Stainless steel brushes, on the other hand, are meant for use on non-ferrous metals like aluminium, tin, and zinc. It is important to use the correct type of brush to avoid contamination and corrosion from mixing dissimilar metals.
To remove rust with a wire brush, you can follow these steps:
- Choose the appropriate wire brush for the type of metal you are working on.
- Attach the wire brush to a power drill or angle grinder. Ensure that the tool operates at or below the maximum speed (Max RPM) specified for the brush attachment.
- Use the wire brush to remove the rust, working until you reach fresh metal.
- Continue until all the rust has been removed, using a softer brush to smooth and polish the surface if needed.
- After removing the rust, you can apply a new coating to the dishwasher rack, such as vinyl repair paint or replacement rack tips.
By following these steps and using the right tools, you can effectively remove rust from a dishwasher rack using a wire brush and restore it to its functional state.

Gluing on protective caps
Dishwasher rack repair kits are a cheap and easy solution to repair rusted dishwasher racks. These kits include dishwasher rack caps that can be glued onto the rack to cover and protect the rusted tines. The caps are available in a variety of colours to match your rack, and they can be purchased from Amazon or Walmart.
Before gluing on the protective caps, it is important to prepare the rack by removing any rust and ensuring the tines are clean and smooth. This can be done by using a wire brush or sandpaper to remove the old rust and vinyl until you reach fresh metal. The tines should then be wiped down to remove any dust or moisture.
Once the rack is prepared, you can begin gluing on the protective caps. It is important to use the glue provided in the kit, as a glue gun will not be effective in the dishwasher's moist, hot environment. The caps should be pushed on tightly to ensure a snug fit.
Some kits may also provide vinyl repair paint, which can be used to coat the freshly cut tips of the tines before slipping on the new vinyl or protective caps. This will help to protect the tines from rust and corrosion.

Using rubberised paint
To recoat the plastic on dishwasher racks using rubberised paint, you can follow these steps:
First, empty the dishwasher and remove all the racks. If necessary, lift up the upper rack to remove it completely. Next, scrub off any rusted portions of the rack using a steel wool pad. Once you've removed the rust, dry the rack with a clean cloth. If there are no rust marks, simply wipe the rack clean with a cloth to ensure it is dry.
Then, apply a dishwasher rack repair rubber solution or rubberised paint to the chipped areas with a brush. You can find these solutions easily on the market. Allow the solution to dry completely, and apply a second coat if necessary. Once you're done, let the solution dry and harden for at least 24 hours.
After the coating has dried, finish by applying dishwasher rack caps to the pointed prongs. These caps are inexpensive and can help protect the prongs, rather than applying multiple coats of the repair solution. Finally, place the newly repaired racks back into the dishwasher and you're done!
Some products you can use include Plasti Dip's ReRack, which comes in a brush-on formula, or you can try paint-on products intended for dishwasher racks.

If your dishwasher rack has only a few rust spots or minor damage, recoating it with a repair kit is a simple and cost-effective solution. However, if the rust has spread extensively, the rack is structurally compromised, or your dishwasher is over a decade old, replacing the rack or the entire dishwasher may be a more suitable option.
