Viomi, Mijia Smart Kettle and Smartmi models feature stainless flasks, touch controls and even integration with the Mi Home. However, even the most advanced appliances require regular maintenance: scale, heating element soak and mold if stored improperly can spoil the taste of water and shorten the life of the device.

In this article, we will discuss 5 proven ways to clean Xiaomi kettle — from classic (vinegar, citric acid) to modern (special tablets and ultrasound), you will learn how to remove contamination without risking damage to the touch panel or nonstick coating, and how to properly care for the device so that cleaning is required less often.

Before you start cleaning, check the warranty conditions of your model. Some procedures (such as mechanical cleaning of the TEG) can cancel the warranty if performed unprofessionally. FAQ answers to frequent questions: can you wash the kettle in the dishwasher, how to get rid of the smell of plastic and what to do if after cleaning the device does not turn on.

1.Why Xiaomi kettle needs to be cleaned regularly

Scale is not just an aesthetic problem: Calcium deposits on a heating element (TEN) increase the boiling time of water by 20-40%, which leads to overuse of electricity. According to research, 1 mm of scale increases energy consumption by 10%. For Xiaomi kettles with a capacity of 1800-2200 watts, this means an extra 50-100 kWh per year - as if you left a light bulb on for 500 hours.

In addition, scale and scalp can cause:

• 🔥 Overheating of heater – the risk of automatic shutdown or even breakage;
• 🦠 Bacterial reproduction – especially in models with temperature maintenance (Keep Warm);
• ☕ Changes in the taste of water – metallic taste or burning smell;
• ⚡ Reduced lifespan – Xiaomi manufacturer recommends cleaning every 1-3 months depending on the hardness of the water.

The Viomi and Smartmi models are equipped with self-cleaning TENG (Descale feature), but this does not negate the need for manual cleaning.The automatic system removes only surface deposits, whereas deep scale requires special tools.

⚠️ Note: If your Xiaomi kettle started to turn off before boiling or makes unusual sounds (hisping, crackling), this may signal a critical layer of scale on the TEN. In this case, cleaning should be done immediately, otherwise the risk of breakage increases by 3 times.

2. How to determine the degree of contamination of the kettle

Before choosing a cleaning method, evaluate the condition of your device.

Look inside the bulb in good lighting - whether white or yellow plaque on the walls is visible?|

Check the bottom of the kettle: are there black spots (nagar) on the heating disc?|

Smell the water after boiling - whether you smell the burn or metal?|

Check the boiling time: if it increased by 30% or more, this is a sign of a thick layer of scale|

Try the water to taste (after cooling) - is there a taste of lime or chemistry?

Depending on the results, select the cleaning method from the table below:

For Xiaomi Viomi models V-KA300 and Smartmi Kettle Pro with stainless flask is permissible mechanical cleaning with a soft sponge. MJKQ) require a more careful approach - abrasives can damage the surface.

💡

If you are in doubt about the bulb material, check the documentation or look at the markings at the bottom of the kettle.Stainless steel is labeled as Stainless Steel or SUS304, Plastic: Tritan or Food Grade Plastic.

3. Method 1: Citric acid purification (the safest method)

7.Keeping Xiaomi's kettle care: How to avoid frequent cleaning

To clean the kettle less often, follow these recommendations:

• 💧 Use filtered or bottled water – this reduces scale formation by 70%.
• 🧼 Wash the kettle after each use - drain the remaining water and wipe the flask with a dry wipe.
• 🔄 Turn on the self-cleaning function (if any) at least 1 time per week. In Viomi kettles, hold the Descale button for 3 seconds to do this.
• 🚫 Do not leave water in the kettle for a long time - this provokes the growth of bacteria and the formation of plaque.
• 📱 Update firmware (for smart models) – new versions often improve self-cleaning algorithms.

For models with Keep Warm (Smartmi Kettle Pro) function, be sure to drain the water after use - heating accelerates scale formation. If you live in a region with hard water, clean the kettle every 2-3 weeks, even if there is little visual plaque.

8.Frequent mistakes when cleaning Xiaomi kettle

Not only can the wrong actions ruin the kettle, but it can also make it dangerous.

• ❌ Use chlorine-containing agents (e.g., Whiteness) – they corrode plastic and leave toxic fumes.
• ❌ Cleaning the kettle when turned on - the risk of short circuit or burn.
• ❌ Apply abrasive powders (such as Pemoluks) - they scratch stainless steel and plastic.
• ❌ Leaving vinegar or acid overnight – this can damage rubber rings.
• ❌ Wash the kettle in the dishwasher – even if the flask is removable, high temperatures deform plastic.

Especially careful with smart kettles (Mijia Smart Kettle), their touch panels are sensitive to moisture — when cleaning, avoid liquid on the top of the case. If water does get into the water, immediately dry the kettle with a hairdryer (cold mode) or leave for 12 hours in a dry place.

1. Dry contacts on the stand (wipe with alcohol).
2. The integrity of the power cord.
3. Has the overheating sensor worked (wait 10 minutes and try again)
