Xiaomi’s automatic soap dispensers (such as the Mijia Smart Soap Dispenser or Viomi Automatic Soap Dispenser) have become an integral part of modern bathrooms and kitchens. They save washing costs, are hygienic and easy to use. However, many users face a problem: factory liquid soap runs out quickly, and buying branded cartridges is expensive. The solution is simple – dilute a regular liquid soap or gel yourself, but there are many nuances.
Incorrect concentration can lead to clogs, weak foam or excessive consumption. In this article, we will analyze the exact proportions for different types of soap, tell you how to avoid errors, and share secrets that will prolong the life of your dispenser, and you will also learn which ingredients are categorically not to add to the tank, this will save the device from breakage.
This material will be useful for both beginners and experienced users of Xiaomi smart equipment, and we tested several recipes on popular dispensers and collected feedback from communities to make your device work like a clock.
What soap is suitable for Xiaomi dispensers: selection criteria
Not every detergent can be put into an automatic dispenser.
- 🧼 Consistency: Optimal viscosity, like kefir. Too thick gels (for example, for shower) clog the pump, and liquid (like shampoo) flow through the valves.
- 🔬 pH neutrality: aggressive alkalis (pH) > 9) corrodes plastic parts. Ideal range: 5.5-7.5.
- 🌿 Composition: Avoid products with abrasive particles (scrabs), silicones or oils - they settle on sensors.
- 🚫 Prohibited components: chlorine, bleach, hydrogen peroxide, alcohol >10%. They destroy seals.
Best suited:
- 🫧 Liquid hand soap (e.g. Dove, Palmolive) – a universal option.
- 🧴 Washing gels marked "for sensitive skin" (less additives).
- 🧼 Concentrated kitchen detergents (diluted more strongly).
Test the product before pouring: drop on a plastic spoon and leave it for 12 hours. If the plastic is not cloudy or deformed, you can use it.
Optimal proportions for dilution: table by soap type
The concentration depends on the initial density of the drug and the dispenser model, and the following are the tested proportions for popular scenarios:
| Type of soap | Proportion (soap:water) | Recommended water volume | Notes |
|---|---|---|---|
| Liquid hand soap (Dove, Fa) | 1:1 | 50–100 ml per 100 ml of soap | Perfect for the Mijia Smart Soap Dispenser. Medium-density foam. |
| Shower gel (Nivea, Garnier) | 1:1.5 | 150 ml per 100 ml gel | Add water gradually – gels often contain thickeners. |
| Kitchen Concentrate (Fairy, AOS) | 1:3 | 300 ml per 100 ml of concentrate | Only for models with high power pumps (for example, Viomi V1). |
| Baby soap (liquid) | 1:0.8 | 80ml per 100ml of soap | Less water – as baby remedies are often thinner than standard ones. |
| Antibacterial soap | 1:1.2 | 120ml per 100ml of soap | Do not dilute too much - the effectiveness of antiseptics decreases. |
Critical error: never use hot water for dilution - it destroys the structure of surfactants (surfactants) and can deform the dispenser tank. The optimal water temperature is 20-25 ° C.
⚠️ Warning: If the soap has been diluted or flakes have come in, you've been using hard water. Add 1 tsp of glycerol to 200 ml of solution, and that stabilizes the mixture.
Step-by-step: how to dilute and pour soap into the dispenser
The process seems simple, but the details determine the outcome.
- Preparation of the tank: rinse the dispenser with warm water (no detergents!) and dry. The residues of the previous soap can react with the new solution.
- Mixing: 📏 Measure the right amount of soap with a measuring cup (usually included). 💧 Add water in small portions, stirring the plastic spatula constantly. 🌀 Stir 2-3 minutes until uniform consistency.

thick but not sticky
Pouring
- 🔌 Disconnect the meter from the network (if it is electric).
- 📥 Pour the mixture through the funnel (comes complete) or gently along the tank wall.
- ⏳ Wait 10 minutes - air bubbles should rise.
- Dosage adjustment: In the Mi Home app, select the "Economic" mode for thick mixtures or "Intensive" mode for liquids.
⚠️ Warning: If the dispenser starts spitting with soap or squeaking, immediately drain the solution and flush the system, these are signs that the pump is clogged with clots or salt crystals.
💡
To flavor soap, add 2-3 drops of essential oil (lavender or tea tree) per 200 ml of solution, but avoid citrus oils - they corrode plastic.
How to prolong the life of the dispenser: care and cleaning
Even perfectly diluted soaps leave a plaque over time, and regular cleaning prevents breakage.
- 🧽 Weekly flush: Pour the residue of soap. Pass 200 ml of warm water with 1 tbsp vinegar (9%) through the dispenser.
Deep cleaning (once a month)
- Remove the tank and rinse under running water.
- Clean the pump with a toothpick (carefully!).
- Dry the parts 24 hours before assembly.
Prevention of raid
Add 1 tsp. citric acid to the solution for 500 ml of soap - this will prevent the formation of lime plaque.
For models with UV-lamp (e.g. Viomi) UV Sterilization Soap Dispenser) after cleaning be sure to wipe the quartz tube with alcohol - this will maintain the effectiveness of disinfection.

Alternative recipes: how to make soap for dispenser with your own hands
If you prefer natural detergents, you can make a soap base yourself. Here are 3 proven recipes:
- Aloe and glycerin soap (calms the skin): 100ml liquid soap without fragrance; 50ml distilled water; 1 tbsp aloe vera gel; 1 tsp glycerin. Mix the ingredients and add 2 drops of lavender essential oil. Suitable for sensitive skin.
- Antibacterial gel with tea tree: 80 ml of baby soap; 100 ml of water; 10 drops of tea tree oil; 1 tsp of honey (optional).
Honey adds antiseptic properties, but can thicken the mixture - if necessary, add water.
Economical kitchen solution
- 50 ml of Fairy concentrate;
- 300 ml of water;
- 1 tbsp. l. soda (for fatty dishes).
