Xiaomi’s electric kettles are among the most popular in the brand’s lineup of smart tech thanks to a combination of technology and affordability. Viomi, Mijia Smart Kettle or Xiaomi Mi Electric Kettle are equipped with precise temperature control, wireless charging and even control through the Mi Home app. However, even the most advanced appliances require regular maintenance: scale, scaling and bacterial deposits not only spoil the taste of water, but also shorten the life of the device.
In this article, we will look at 5 proven ways to clean Xiaomi kettles, from classic citric acid techniques to little-known life hacks to remove persistent stainless stain on the heating element. Special attention will be paid to smartly controlled models: how to keep temperature sensors intact and maintain functionality after cleaning. Also, you will learn what tools are categorically not used for kettles with ceramic or stainless coating – this is critical information that is often missed in standard instructions.
Why Xiaomi’s kettle should be cleaned regularly
Scale is not just an aesthetic issue: Xiaomi kettles with a hidden heating element (like the Viomi model) V-KETTLE300) The lime plaque is formed on the bottom and walls, which degrades the thermal conductivity:
- 🔥 Overheating of heater – the kettle boils water longer, spending 20-30% more electricity.
- ⚡ Sensor breakdown – in smart kettles, temperature sensors can fail due to plaque.
- 🦠 Bacterial reproduction – porous scale structure is ideal for microbes, especially if the kettle is rarely washed.
- 💧 Change in the taste of water - a metallic taste appears already with a layer of scale 1-2 mm thick.
The manufacturer recommends cleaning Xiaomi kettle every 1-2 months with daily use (or after 30-50 boiling cycles).However, if your region has hard water (over 7 mg-eq / l), the interval should be reduced to 3-4 weeks.
⚠️ Attention: In Xiaomi kettles with Keep Warm function, scale is formed 1.5 times faster due to constant water heating.
How to determine if Xiaomi teapot is time to clean
Don't wait for the scale to become visible to the naked eye, and the following signs indicate the need to clean:
| Sign. | What's going on? | Pollution level |
|---|---|---|
| Noise when boiling | Water boils stronger than usual, foreign sounds are heard (cracking, hissing) | Weak (plain of 0.5-1 mm) |
| Increased boiling time | The teapot warms the water for 1-2 minutes longer than before | Medium (plainage 1-2 mm) |
| Automatic shutdown before boiling | The kettle turns off prematurely due to false alarm of the sensor | Strong (plaque) >2 mm, risk of breakdown) |
| Metallic taste of water | The taste and smell of the water changed, white precipitation appeared | Any (requires urgent cleaning) |
In Xiaomi’s smart kettles (such as the Mijia Smart Kettle Pro), a notification in the Mi Home app may signal the need to clean. If the model supports self-diagnosis, it will display the error code. E4 or E5 — This is a direct indication of the critical scale level.
Preparing Xiaomi kettle for cleaning: 5 mandatory steps
Before proceeding with the removal of scale, perform these actions so as not to damage the device:
Disconnect the kettle from the network and allow it to cool to room temperature
Remove the remaining water and wipe the internal walls with a dry cloth
Remove the filter (if any) and rinse it separately under running water
Check the integrity of the sealing rubber on the cover
Prepare protective equipment: gloves and mask (when working with acids)-->
Pay special attention to the filter: in Xiaomi Viomi models, it is often removable and requires separate cleaning. If the filter is clogged with scale, it can be soaked in a solution of citric acid (1 tbsp per 200 ml of water) for 15-20 minutes. For kettles with stainless steel (for example, Mi Electric Kettle Pro), avoid abrasive sponges - they scratch the surface, accelerating the formation of plaque.
⚠️ Warning: Don't immerse Xiaomi kettle in water completely! even if the case is sealed, it can damage electronic components (especially in touch-controlled models.
Top.-5 Ways to clean the teapot Xiaomi from scale
The choice of method depends on the material of the kettle, the degree of contamination and the availability of smart features. V-KETTLE300 (ceramics) and Mijia Smart Kettle (stainless steel) – results in the table below.
1. Citric acid - classic for all models
The safest and most effective method for ceramic and stainless kettles, suitable for regular cleaning.
- 🍋 Mix 2 tbsp. l of citric acid with 1 liter of water.
- 🔥 Bring the solution to a boil, then leave for 30-60 minutes.
- 🧽 Pour the solution, wash the kettle with running water 2-3 times.
- 🔄 Repeat boiling with pure water to remove acid residues.
For stable scale, you can increase the concentration to 3 tbsp. l. per 1 l, but do not exceed this value - an aggressive solution can damage the seals.
2. vinegar - for severe contaminants (with caution!)
Effective against thick scale, but has drawbacks: a pungent smell and the risk of corrosion of metal parts. Do not use for kettles with ceramic coating!
- 🥄 Mix 9% vinegar with water in a 1:1 ratio.
- 🕒 Pour the solution into a kettle and leave for 1-2 hours (do not boil!).
- 🚿 Wash thoroughly 3-4 times, then boil with clean water.
Why can’t you boil vinegar in a Xiaomi kettle?
3.Soda. + Hydrogen peroxide - to remove the odor and scent
The ideal way to do this is if you smell like a burn or have a dark coating on the TEN, and it's good for all materials.
- 🧂 Mix 2 tbsp. l. soda with 1 tbsp. l. 3% hydrogen peroxide.
- 🧽 Apply the gruel to contaminated areas with a sponge (not abrasive!).
- ⏳ Leave for 15-20 minutes, then rinse with warm water.
To enhance the effect, you can add a few drops of liquid soap, which also helps to whiten the yellowed walls of the kettle.
4. carbonated drinks (Coca-Cola, Sprite) - a non-standard, but working method
Phosphoric acid in the composition of soda dissolves scale, but it is often not recommended to use this method - sugar can remain on the walls.
- 🥤 Pour soda into the kettle (up to the maximum mark).
- 🕒 Leave for 1-2 hours (no need to boil!).
- 🧼 Rinse 3-4 times with detergent.
5. Specialty products (e.g. Topperr 3031 or Sano Anti-Kalk)
Professional antinakipines are faster and more gentle than traditional methods, suitable for smart kettles with sensors, as they leave no sediment.
- 📖 Follow the instructions on the package (usually 1 bag per 1-1.5 liters of water).
- ⏱ Exposure time: 15-30 minutes.
- 🔄 After cleaning, be sure to boil the water 2 times.
💡
For Xiaomi kettles with smart control (Mi Home) after cleaning, reset the temperature settings in the application.
How to Clean a Heating Element (TEN) in a Xiaomi Kettle
In models with open heater (for example, Xiaomi Mi Electric Kettle) 1.5L) The heating element gets polluted faster:
- Turn off the kettle and wait for it to cool down.
- Prepare a solution: 1 tbsp. l. citric acid + 0.5 litres of water.
- Pour the solution into the kettle and turn on the heating before boiling.
- After cooling, carefully remove the softened scale with a soft brush (for example, a toothbrush).
- Wash the TEN under a stream of water, avoiding moisture on the contacts.
For hidden TENS (as in Viomi) V-KETTLE300) mechanical cleaning is prohibited - use only chemical methods (citric acid, vinegar). If the plaque is not removed, repeat the procedure 2-3 times at intervals of 1 day.
💡
If dark spots (nagar) appear on the TEN, wipe it with a cotton-coated disk dipped in a solution of soda with water (1:1). Do not use metal brushes - they damage the protective coating.
What not to do when cleaning the kettle Xiaomi
Some "people's" councils can permanently ruin the kettle.
- ❌ Boil a kettle with vinegar - the pairs destroy plastic and rubber seals.
- ❌ Use abrasives (sand, metal sponges) - they scratch stainless steel and ceramics.
- ❌ Soaking the kettle in water - this leads to corrosion of contacts and breakage of electronics.
- ❌ Clean with chlorine-containing agents (for example, "White") - they leave toxic residues.
- ❌ Ignore filter cleaning – clogged filter worsens the taste of water and reduces pressure when pouring.
In kettles with wireless charging (such as Xiaomi Mi Smart Kettle Pro), avoid moisture on the base - this can disable the induction coil. After cleaning, wipe the bottom of the kettle dry.
How to Care for Xiaomi Teapot to Clean Less
Compliance with these rules will reduce the formation of scale by 2-3 times:
- 💧 Use filtered or bottled water to reduce stiffness by 70%.
- 🔄 After each use, drain the remaining water - standing water forms a plaque faster.
- 🧼 Once a week, wash the kettle with a soft sponge with soap (without abrasives).
- 🌡 Do not re-boil the water, it increases the concentration of salts.
- 📱 In smart kettles, turn off Keep Warm mode if you are not using it.
For models with Mi Home, set up in-app cleaning notifications. e.g. in Viomi V-KETTLE300 You can turn on the service reminder option at intervals of 30 days.
