Removing Rust from Your Coffee Maker


If your coffee pot warming plate is no longer keeping coffee warm, it might be due to rust accumulation. A dirty warming plate won’t transfer heat. First, make a solution of water and oxalic acid. Use hand protection for this since the acidic properties of the solution can be harmful.


Thoroughly clean any coffee residue off the warming element using a damp and lint-free cloth with soapy water.


Next, apply the oxalic solution to the warming element. You should allow this to sit and soak for a little bit so it can soften the rust.


Remove the warm water solution carefully using a dry cloth. Wipe the warming element down with a damp cloth and soap once more, rinse it off, and then dry it thoroughly.

Reapplying Heat-Resistant Paint


If you haven’t, clean the heating element unit of your coffee machine thoroughly using hot water and vinegar.


Next, take off your coffee pot warming plate by following the directions provided by coffee machine manufacturers. This will keep other components in coffee makers safe, such as the brew basket.


Set up a safe area for the painting process. Make sure you use heat-resistant spray paint, or you could end up with a dangerous situation and noxious fumes. Automotive engine paint works well.


Allow the coffee machine plate to dry completely. Then reinstall it, brew coffee, and enjoy a cup of coffee from your freshly repaired machine.


If you’re diving into the repair revolution, learning how to fix a spring in a coffee maker is a great next step.


Be careful about your destination for tech repair news. Always check with your manufacturer for official information before investing in a selection of precision tools.


How do coffee makers work?

That depends on the type of model you purchase. There is a wide selection of styles out there beyond drip coffee makers. A popular style for those with little time is pod coffee makers.

Is repairing my coffee maker worth it?

Unless you have an exceptional appliance, it’s almost always better to just purchase a new model. Most of the time, the repair cost is higher than a new unit would be.

Should I try to repair a dangerous coffee pot?

Absolutely not. They don’t cost enough to justify taking a chance on a dangerous coffee pot. If the glass carafe is compromised, it’s time to look into selecting one of the drip coffee makers on the market.

What are the best cleaning instructions for a coffee appliance?

Most of them will include ingredients like baking soda, white vinegar, and lemon juice. You can also use a commercial product made by the manufacturer.
