Keeping your water distiller clean is essential to ensure it consistently delivers pure, safe, and great-tasting distilled water. Even the best distillers can accumulate bacteria, mineral deposits, and other impurities over time. In this complete guide on how to clean water distiller, we’ll walk you through the reasons why cleaning matters, when to clean, the tools you’ll need, and the exact steps to maintain your distiller in top condition.
Why Cleaning Your Water Distiller Matters
A water distiller purifies water by boiling it into steam and condensing that steam into clean water. But during each cycle, minerals like calcium and magnesium, as well as bacteria and organic matter, stay behind in the boiling chamber. Without regular cleaning, this buildup can:
-
Reduce distillation efficiency
-
Contaminate the clean water
-
Cause unpleasant smells or tastes
-
Damage internal components
-
Increase energy consumption or fire risk

Yes. Vinegar can remove minor buildup, while commercial descalers are effective for tougher deposits. Always refer to your user manual.
2. What if I see rust?
Most “rust” is actually a harmless layer of chromium oxide from welding, not actual corrosion. You can clean it gently with vinegar if needed.
