How to properly dilute liquid soap for Xiaomi dispenser: proportions, errors and secrets

Xiaomi’s automatic soap dispensers (Viomi, Mijia Smart Soap Dispenser) have become an integral part of smart bathrooms, saving washing costs, dosing portions, and even highlighting liquid in the dark. But many users face a problem: factory liquid soap runs out quickly, and filling with original cartridges is expensive, the solution being to dilute concentrated soap or adapt a conventional gel to the device.

But here’s the catch: the wrong proportions lead to nozzle clogs, weak foam or, conversely, excessive consumption. In this article, we will analyze the exact proportions for different types of soap, the nuances of working with popular models of Xiaomi dispensers (including Viomi). V-SD01 and Mijia MJSDJ02YL), And also unique life hacks to clean the system of lime plaque without disassembling the device. Save up to 70% on the refueling without loss of quality!

Why you can not pour undiluted soap in the Xiaomi dispenser

The manufacturer recommends using only original liquid cartridges, but this is a marketing ploy. In fact, the device works with any liquid soap or gel, if two key conditions are met:

• 🔹 Viscosity: Too thick a gel (for example, for shower) clogs the microscopic channels of the nozzle.
• 🔹 Foaming: Concentrated detergents foam too actively, leading to "spitting" and leaks.
• 🔹 Chemical composition: Abrasive particles (scrabs) or aggressive surfactants (in cheap means) destroy silicone pump seals.

Ignoring these rules leads to a breakdown:

What soap is suitable for dilution: TOP-5 variant

Not all detergents are equally useful for the dispenser, but the best option is transparent gels without abrasives with a neutral pH (5.5-7.0).

• 🚫 Microbeads (scrabs, peels) - scratching the internal details.
• 🚫 Strong aroma - essential oils oxidize silicone.
• 🚫 glycerin >10% – crystallizes when water evaporates.
• 🚫 Chlorine or bleach – destroy plastic.

Best bases for dilution (according to the reviews of the owners of Xiaomi Viomi):

1. Baby liquid soap (e.g. Johnson's Baby) Bübchen) — soft formula, not aggressive to sealants.
2. Antibacterial hand gel (no alcohol!), for example, Safeguard - good foaming when diluted 1:3.
3. Concentrate for automatic dispensers (for example, Ecover) - designed for dilution, environmentally friendly.
4. Conventional liquid soap ("Devest", "Sorte") - budget option, but requires filtering from the sediment.
5. Shampoo for sensitive scalp (for example, La Roche-Posay Kerium) – suitable for dispensers with the function of “foam”.

⚠️ Note: Do not use products marked "hand washing" or "warewareware" containing salts that settle on the pump and block its operation through the pump. 2-3 weekdays.

Optimal dilution proportions: table for different types of soap

The ratio of water to soap base depends on the original viscosity of the product. The universal formula is 1 part soap to 2-4 parts water, but for accuracy use the data below:

💡

To test the viscosity, drop the finished mixture on an inclined surface. ~1 cm/sec - the correct proportion.

How to mix correctly:

1. Heat the water to the specified temperature (use a bath thermometer).
2. Add the soap base with a thin stream, stirring the silicone spatula constantly.
3. Let the mixture stand for 1-2 hours - this will remove the air bubbles.
4. Strain through a coffee filter or gauze to remove undissolved particles.

Step-by-step instructions for filling the Xiaomi dispenser

Before refueling, you need to prepare the device.

Disconnect the device from the network|Remove the upper cover (press the latch from behind)|Remove the remnants of old soap with a washing solution|Dry the internal tank with a paper towel|Check the integrity of the silicone pad-->

Step 1: System flushing

If you are switching from the original cartridge to a homemade mixture, rinse the dispenser with vinegar solution (1 tbsp per 200 ml of water):

1. Pour the solution into the tank.
2. Turn on the device and start the dosage 5-7 times.
3. Wash with clean water (2-3 cycles).

Step 2. Gasing

Use a crater with a narrow nose or a needleless syringe to avoid the spills. Fill the tank by no more than 80% - this will prevent overflows when the liquid is heated.

Step 3: Calibration of dosage

After refueling, check the amount of portion issued:

• 📏 Run the dispenser in minimum mode (usually the button "1»).
• 📏 Collect the issued soap in a measuring cup.
• 📏 If necessary, adjust the settings in the Mi Home application (Dispenser Settings section). → Dose Volume).

💡

The ideal portion of soap for one press is 0.8-1.2 ml. If the volume exceeds 1.5 ml, increase the proportion of water in the mixture.

Common Mistakes and How to Avoid Them

Even the most experienced users have miscalculated soap dilution, and here are the most common ones:

⚠️ Warning: If the dispenser starts to sneeze after refueling, there is still air in the system. Eliminate it by pressing the dosage button 10-15 times in a row at 2 seconds intervals.

• 🔴 Use of tap water → It leads to lime plaque. Solution: use distilled or boiled water.
• 🔴 Stirring with a metal spoon → Oxidizes the components of soap. Solution: just silicone or plastic tools.
• 🔴 Storage of the finished mixture >7 days → It's spreading and losing properties. Solution: Prepare portions for 3-5 days.
• 🔴 Cold-mixing refueling → It increases the viscosity. Solution: heat the mixture to 30-35.°C before pouring.

How to clean the dispenser from plaque without disassembly

Over time, the inside of the tank and the tubes will form a film of soapstone, which can be removed without removing the device.

Method 1. Vinegar washing (for light plaque)

1. Mix 100 ml of table vinegar (9%) and 100 ml of hot water (60)°C).
2. Pour the solution into the dispenser and leave for 1 hour.
3. Start 5-7 cycles of dosage, then rinse with clean water.

Method 2. Citric acid (for heavy deposits)

1. Dissolve 1 tsp of citric acid in 150 ml of water.
2. Load the dispenser pump into the solution for 20 minutes (hold the dosage button).
3. Wash the system with water with the addition of 1 drop of glass washing agent (remove the greasy film).

Method 3: Ultrasonic cleaning (for models with removable tank)

If your dispenser allows you to remove the tank (for example, Viomi). V-SD01), Put it in an ultrasonic water bath for 5 to 10 minutes. Water temperature is 40.°C, frequency 40 kHz.

Lifehacks to save soap and extend the life of the dispenser

Reduce your cleaning product consumption by 40% with these tricks:

• 💡 Add 10% glycerol – reduces evaporation of water from the mixture, prolongs the shelf life.
• 💡 Use Eco mode in the Mi Home app (reduces portion by 30%).
• 💡 Install dispenser away from heating appliances - heat accelerates mix dissection.
• 💡 Rinse the system 1 time every 2 weeks with a weak solution of soda (1 tsp. per 200 ml of water).
• 💡 Store the spare mixture in a dark glass bottle - the light destroys the surfactant.

💡

To flavor homemade soap, add 2-3 drops of lavender or tea tree essential oil per 100 ml of the mixture. But avoid citrus oils - they corrode plastic.

How to extend the life of the pump:

• ⚙️ Do not allow the dispenser to work "dry" (without liquid).
• ⚙️ Once a month, lubricate silicone pad with food vaseline.
• ⚙️ Avoid sudden temperature changes (do not place the device near the shower).
