Corrosion in Home Appliances – What It Is and Why It Matters

If you’ve ever seen a rusty patch on a washing machine drum or a white crust inside a fridge, you’ve met corrosion. It’s the slow eating away of metal caused by moisture, chemicals or salty air. In the UK’s coastal towns, like Bognor Regis, the salty breeze can speed up the process, turning a good appliance into a costly replacement faster than you expect.

Corrosion isn’t just an eyesore. It can weaken structural parts, cause leaks, and even short‑circuit electrical components. The result? A dishwasher that won’t pump, an oven that won’t heat, or a water heater that leaks. Spotting it early can save you time, money, and a lot of hassle.

Common Signs of Corrosion

Knowing what to look for makes a huge difference. Here are the most common clues:

  • Rust spots or orange‑brown stains on metal surfaces – especially around door seals, hinges, and under the appliance.
  • White or greenish deposits on the inside of fridges, freezers or water heaters – often a sign of mineral build‑up that leads to corrosion.
  • Unusual noises like scraping or rattling, which can mean a corroded bearing or motor shaft.
  • Leaks or puddles beneath the unit – a corroded pipe or pump seal is usually the culprit.
  • Weak or intermittent power – corrosion on wiring or contacts can cause voltage drops.

When you notice any of these, it’s worth checking the surrounding area for excess moisture. Leaky pipes, condensation, or even a damp kitchen floor can create the perfect environment for corrosion to thrive.

Preventing and Fixing Corrosion

Prevention is cheaper than repair, so start with a few simple habits:

  1. Keep appliances dry. Wipe down spills immediately, especially around seals and gaskets. Use a de‑humidifier in damp rooms.
  2. Use the right cleaning products. Harsh acids can strip protective coatings. Stick to mild detergents or products designed for appliances.
  3. Check ventilation. Good airflow stops moisture from pooling. Clean filters on extractors and ensure fridge coils aren’t covered in dust.
  4. Apply protective spray. A light coat of silicone spray on metal hinges and moving parts can create a moisture barrier.
  5. Schedule regular maintenance. A quick professional check once a year catches early corrosion before it spreads.

If you already have rust, you can often fix it yourself:

  • Sand or file the rusted spot to remove loose material.
  • Clean the area with a mixture of water and baking soda to neutralise any remaining acid.
  • Prime and paint with a rust‑inhibiting metal primer, then top it with appliance‑safe paint.
  • Replace seals or gaskets that are badly degraded – they’re cheap and make a big difference.

For electrical components or sealed units like water heaters, it’s safer to call a professional. Trying to repair a corroded heating element without the right tools can be dangerous and might void warranties.

At Bognor Regis Appliance Repair Experts we see corrosion every day, from old washing machines to brand‑new ovens that sit near a kitchen sink. Our technicians know how to strip away rust, replace damaged parts and apply protective finishes that keep your appliances running longer.

Bottom line: keep moisture at bay, clean regularly, and don’t ignore the first hint of rust. A little attention now means fewer breakdowns later, and your appliances will thank you with years of reliable service.
