Why the scale in Xiaomi’s kettle is dangerous – and when to remove it
Xiaomi’s electric kettles (including the Viomi and Mijia models) are known for their stylish design and smart features, from precise temperature control to app control. But even the most advanced appliances are not immune to scale. This white or yellowish coating doesn’t just spoil the look: it reduces thermal conductivity, making the TENG work for wear and tear, and can cause breakdown.
The manufacturer recommends that the kettle be cleaned at least 1 time every 1-2 months (with daily use). However, the rate of scale formation depends on the hardness of the water: in regions high in calcium and magnesium, you will have to clean more often. How do you know what time to act?
- 🔍 Visible plaque on the walls or bottom (even a thin layer already reduces the efficiency of heating).
- ⏱️ Increased boiling time – if the water is warmed longer than usual.
- 🔊 Uncharacteristic noise when working (hisping, crackling).
- 💧 Change in the taste of water – a metallic or bitter taste.
Important: scale in Xiaomi kettles with hidden TEN (for example, in the Viomi V-KETTLE300 or Mijia Smart Kettle Pro models) accumulates faster than in open spiral heaters. This is due to less water circulation around the element. Neglecting cleaning can lead to overheating and automatic shutdown of the kettle due to the protection operation.
Preparing the kettle for cleaning: what can and can not be done
Before you start removing scale, you need to properly prepare the device, which will save it from damage and ensure maximum efficiency of the procedure.
General rules of training:
- ⚡ Turn off the kettle and wait for a full cooling (at least 30 minutes).
- 🧼 Remove the remaining water and rinse the inner surface with warm water.
- 📱 Disconnect smart modules (if the kettle supports control via Mi Home): some models (e.g. Viomi) V-KETTLE300) have a removable base with sensors - it is better to remove it.
- 🧽 Use soft sponges or wipes – abrasive materials scratch stainless steel and nonstick coating.
⚠️ Warning: Never immerse the kettle in water whole - this will lead to a short circuit! even if the model has a sealed body (like the Mijia Smart Kettle Pro), the contacts on the base are not protected from moisture.
For models with display or touch buttons (such as the Viomi V-KETTLE300), avoid invasive solutions on electronic elements. When cleaning the outer surface, use a wet microfiber - without alcohol or acetone.
5 proven ways to clean Xiaomi teapot from scale
There are several methods of fighting scale, but not all of them are equally safe for Xiaomi equipment. We have selected the 5 most effective and gentle ways that will not damage the internal coating and electronic components.
1.Citric acid is a classic with caveats
It is the most popular tool due to its availability and relative safety, but for Xiaomi kettles, it is important to keep proportions: excess acid can damage rubber seals (for example, in models with a thermometer).
Instructions:
- Pour 1-1.5 liters of water into the kettle (up to the maximum mark).
- Add 20-25 g of citric acid (1-1.5 tbsp. spoon without a slide).
- Bring the solution to a boil and turn off the kettle.
- Leave for 30-40 minutes, then drain the solution and rinse the kettle 2-3 times with clean water.
⚠️ Warning: If you have left a white coating after the procedure, it is undissolved salts. Re-boil with a new portion of water (without acid) to remove the residues.
Pour water to the maximum mark |Add 20–25 g of acid (no more!) |Boil and turn off |Wait 30–40 minutes |Wash 2-3 times with clean water-->
2 Vinegar - quickly but with caution
Acetic acid can even cope with old scale, but it can not be used for models with stainless steel (for example, Mijia Smart Kettle Pro). It can cause corrosion of metal and damage non-stick coatings. It is only suitable for kettles with ceramic or glass interior coating (like the Viomi V-KETTLE300).
Proportions and procedures:
- Mix 100 ml of 9% vinegar with 1 liter of water.
- Bring to a boil, turn off and leave for 20-25 minutes.
- Thoroughly rinse the kettle 3-4 times, then boil it with clean water and drain it (this will remove the smell of vinegar).
💡
To neutralize the smell of vinegar, add to the water for the last boiling zest of lemon or orange.
3 Baking soda is a mild but long method
Soda is suitable for regular prevention when scale is not yet enough, it does not damage any coatings, but takes longer to act.
How to use:
- Dissolve 2-3 tablespoons of soda in 1 liter of hot water (not boiling water!).
- Pour the solution into the kettle and leave for 2-3 hours (you can overnight).
- Wash the kettle with a sponge, then rinse with clean water.
To enhance the effect, you can add 1 tbsp of salt to the soda solution, which will accelerate the dissolution of scale. But after this procedure, be sure to boil pure water 1-2 times in the kettle.
4 Special facilities for and against
In household chemicals stores, scale removal products (Topperr, Sano, Bagi) are effective, but have a number of disadvantages:
- ❌ They may contain aggressive surfactants that spoil the taste of water even after washing.
- ❌ Not everyone is suitable for smart kettles with sensors (risk of damaging electronic components).
- ✅ Plus: quickly cope with a thick layer of scale (in 15-20 minutes).
If you do decide to use this product, choose gel or liquid forms - the powders can settle on the bottom and require mechanical cleaning. Follow the instructions on the package, but reduce the exposure time by 20-30% so as not to damage the coating.
5.Sparkling drinks - an unexpected life hack
Coca-Cola or sprites contain orthophosphoric acid, which dissolves scale, a method suitable for emergency cleaning, but not for regular use.
How to apply:
- Pour 0.5-1 liters of soda into the kettle (pre-released gas).
- Bring to a boil, turn off and leave for 10-15 minutes.
- Wash the kettle 3-4 times with clean water, then boil the water in it and drain.
⚠️ Warning: After using soda, the teapot may still have a sweet taste. To eliminate it, wipe the inner walls with a slice of lemon.
💡
For Xiaomi kettles with smart functions (connection to Mi Home, display), gentle methods are preferred: citric acid or soda. Aggressive means (vinegar, chemistry) can damage electronic components.
What not to do when cleaning the kettle Xiaomi
Some popular advice can not only ruin the kettle, but also make it dangerous for health.
| Method | Why is it dangerous? | What's the threat? |
|---|---|---|
| Boiling with salt | Salt does not dissolve scale, but settles on the TEN. | Accelerates metal corrosion, reduces service life |
| Use of abrasive sponges (metallic, hard) | Scratching nonstick coating and stainless steel | Accumulation of rust, deterioration of the taste of water |
| Boiling with chlorine-containing agents (for example, "White") | Chlorine eats away at rubber seals and plastic parts | Leaks, thermostat breakage, toxic fumes |
| Cleaning with a knife or other sharp objects | Damage to TEH and internal coating | Short circuit, uneven heating of water |
Especially careful with models that have the TEN built into the bottom (for example, the Mijia Smart Kettle Pro), damage to the heating element in such kettles often leads to the inability to repair — you have to buy a new appliance.
How to care for Xiaomi teapot so that scale was less
Regular cleaning is good, but it's even better to prevent scale from forming. Here are some proven ways to do this:
- 💧 Use filtered or bottled water to reduce calcium and magnesium salts by 60 to 80%.
- 🔄 Do not boil the same water twice – when reheated, salts settle faster.
- 🍋 Add a slice of lemon to the water with each boiling - a weak acid slows the formation of plaque.
- 🧂 Wash the kettle after each use – drain the remaining water and wipe the inner walls with a napkin.
- 📱 Watch out for notifications in Mi Home – some smart kettles (like Viomi) V-KETTLE300) informing about the need for cleaning.
If you live in a very hard water region, consider installing a main filter or using ion-exchange cartridges (like Brita) that will extend the life of not only the kettle but also other household appliances (washing machine, dishwasher).
