How to remove dishwasher rack rust?

How to remove dishwasher rack rust?

Looking for something equivalent to ReRack (vinyl rack repair) to coat dishwasher rack prongs that have rusted (will remove rust with steel wool first) - prefer nail polish / paint on type applicator as opposed to aerosol.

Re: Dishwasher rack rust

Hi @Meg5,


Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you join us.


Unfortunately, I am not aware of a product with this specific purpose.


My suggestion would be to contact the dishwasher's manufacturer to see if they can send you a replacement rack.


Allow me to tag some of our helpful members to see if they have any ideas, @Dave-1, @DIYGnome, @elbow.


Let me know if you have any other questions.

Afternoon @Meg5 

Mmmmm I think I know what you are after and must admit it would be nice to know a product to use.


I went looking for rubberised paint and came back to this eventually Rust-Oleum 340g White Leakseal Rubberised Coating Spray 

Please Note! Its definently "outside scope of use" but thinking outside the box and possibilities. I am not sure how it would stand up in a dishwasher/damage a dishwasher or seperating away from the metal.


Also if the rack prongs have rusted within a dishwasher it suggests to me that they are faulty as they should only be stainless and something has gone wrong with the manufacturing process. At the very leasy the rust needs to be treated more then just removing first. Not sure of what food grade type material would be accptable. 


All my answers keep coming back to "food grade" as you want it to be able to used around human consumption items, none of my ideas specify that :/.

Hi @Meg5,

I would have thought vinyl paint would be useful for the recoating. RE-rack sounds perfect, is there a reason you're not using this?

Re: How to remove dishwasher rack rust?

Hello @Meg5 TBH I've never owned a dishwasher and only operated a Commerical type in a work place so not something I'm overly familiar with, given there is no supplied photos to illustrate the extent of the corrosion I can only provide a best guess, have you considered a prong repair kit?


There are kits like these available online and likely through the special order department at Bunnings as well (as seen below) 👍





How to fix rusty dishrack?

I have a small piece on the dishwasher rack where the plastic has split and started to rust. A replacement rack would cost more than $100 dollar.
i am hoping to get some advice on after removing the rust, what should the remaining metal be covered with?

Something that would withstand the heat and not be toxic.

Re: How to fix rusty dishrack

Hello @softsquares 


Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thanks for sharing your question about your dishrack.


I'm sorry, but I'm currently not aware of a product that will stop the rusting on your dishrack. Unfortunately, most of the repair items I'm aware of are not food safe or made to operate in high temperatures. It's possible for you to sand down the rusted parts, but it will eventually come back.


I'm afraid I can only suggest that you replace the rack with a new set. You can at least be sure that the new rack will give you a few years of service and be safe to use.


If you have any other questions we can help with, please let us know.
