Corrosion in Home Appliances: How It Happens and What to Do

If you’ve ever seen rust on a washing machine drum or a white crust inside a dishwasher, you’ve dealt with corrosion. It’s not just an eyesore – it can make appliances leak, break down faster, and cost you more in repairs. The good news? You can spot the signs early and take easy steps to keep corrosion at bay.

Why appliances get corroded

Most appliances have metal parts that sit in water, steam or humid air. When water meets metal, a chemical reaction creates rust. Hard water, salty air (especially near the coast), and a bit of neglect speed up the process. Even tiny scratches on a surface give corrosion a place to start. Over time, the rust eats away at the metal, weakening it and causing leaks.

Simple ways to stop corrosion before it hurts

Dry it out: After each use, wipe down wet spots on the inside of dishwashers, fridges and washing machines. Leave doors open for a few minutes so air can dry the interior.

Use the right detergent: Harsh chemicals can strip protective coatings. Stick to the manufacturer’s recommended cleaners and avoid abrasive powders.

Check water quality: If you have hard water, consider a water softener or a filter for appliances that use a lot of water. Fewer minerals mean less rust.

Seal scratches: Small chips in a metal surface can become rust hotspots. Use a touch‑up paint made for appliances or a rust‑inhibiting sealant to cover them.

Regular maintenance: Run a cleaning cycle on your dishwasher once a month with a vinegar rinse. Flush the washing machine’s pump filter regularly. These simple habits keep buildup away and let you catch rust early.

When you do see rust, act fast. A light rust spot can often be removed with a non‑scratching pad and a bit of baking soda paste. For heavier rust, a commercial rust remover followed by a protective coating works well. If the corrosion has eaten through a part, it’s time to call a professional – trying to keep a broken component can cause leaks or bigger damage.

Remember, corrosion isn’t a mystery. It’s just metal meeting water under the right conditions. By keeping things dry, using the right cleaners, and looking out for early signs, you’ll extend the life of your appliances and avoid costly repairs.

Got a corroded kettle or a rusty fridge door seal? Follow the steps above, and you’ll see a big difference. And if you ever feel stuck, a quick call to a local repair service can save you time and headaches.
