How to clean the irrigator Xiaomi inside: from plaque to mold

Why cleaning the irrigator from the inside is not a luxury, but a necessity

Xiaomi irrigators (e.g. Oclean models) W10, Xiaomi Mijia Portable or Soocas W3) They've become an integral part of oral hygiene for thousands of users, but few people realize that inside the device is the perfect environment for bacteria to grow, with moisture, warm temperatures and toothpaste residues creating a climate comparable to a tropical swamp. Studies show that after 2 weeks of use without cleaning, colonies of mold appear in the tank and tubes, and lime plaque settles on the walls, which becomes a breeding ground for Streptococcus mutans - the main cause of caries.

The manufacturer recommends deep cleaning of internal components at least 1 time a month, but in practice users face problems much earlier: nozzles clog, an unpleasant smell appears, and the water jet loses pressure. In this article, we will analyze how to clean the Xiaomi irrigator inside without risk of damaging electronics, what tools to use for different types of contamination and how to avoid errors that shorten the life of the device.

Spoiler: If you've never cleaned the tank from the inside, be prepared for surprises. 80 percent of the time you first open it, users find black mold spots on silicone seals and white plaque on the heating element (if it's in the model), but don't worry, we'll show you how to get the device back to its original purity.

What parts of the Xiaomi irrigator should be cleaned

Xiaomi’s irrigation design (including pumped and ultrasonic models) involves several critical areas where contaminants accumulate, and skipping one of them negates all care efforts:

• 💧 Water reservoirs: limestone deposits here (especially in regions with hard water), and mucus forms at the bottom due to bacteria. In heated models (for example, Oclean X Pro Elite), scale appears on the heating element.
• 🌀 Pipes and hoses -- the inner ducts are clogged with microparticles of dental plaque and paste, and the bends form "dead zones" where water stagnates.
• 🔌 Nozzles and tips -- small holes get clogged with calcium salts, and rubber seals get covered with mold, which leads to a decrease in the jet pressure.
• ⚡ Pump and valves - in mechanical models, dirt accumulates on the blades of the pump, and in electronic contacts are oxidized due to moisture.
• 🔋 Base and charging contacts – oxidation of metal parts leads to poor contact and slow charging.

Many users limit themselves to washing the tank under the tap, but this does not solve the problem comprehensively. For example, mold in the tubes can go unnoticed for months until it begins to release toxins into the water.

What can be cleaned irrigator inside: safe and prohibited products

The choice of product depends on the type of contamination and material of the parts. Xiaomi in the instructions for the models Oclean and Soocas warns that harsh chemicals (such as chlorine or acetone) destroy silicone seals and plastic.

Critical: for models with ultrasonic technology (e.g. Soocas) H3) You can't use abrasives, they damage the membrane of the emitter, and avoid products with a strong smell (such as ammonia), as it can persist in plastic and spoil the taste of water.

⚠️ Note: If your model has a silver ion coating (e.g., Oclean) W10), Do not use chlorine-containing products – they neutralize the antibacterial effect of silver.

Step-by-step: how to clean the tank and tubes inside

So the hard part is, deep cleaning of the internal canals, which requires a soft brush (like a toothbrush), cotton swabs, a needleless syringe (20 ml) and a cleaning product of your choice, which takes 30 to 60 minutes, but it's worth it.

1. Disassembly of the irrigator

Take the tank off the grid. Remove it (most models use latches or threads); unplug the hose from the base, usually by turning counterclockwise or pressing the lock; don't put too much effort into keeping the plastic mounts intact.

In models with removable pump (for example, Xiaomi Mijia Portable) carefully remove the pump unit, having previously photographed the location of the wires, if you are afraid to confuse when Assembly.

2. Cleaning the tank

1. Pour into the tank a warm solution of citric acid (20 g per 1 liter of water) or diluted vinegar (1: 1 with water).
2. Close the lid and shake it so that the liquid gets to all corners. Leave for 15 to 30 minutes.
3. Use a soft brush to clean the walls. For hard-to-reach areas (such as under the O-ring), use a cotton swab dipped in solution.
4. Wash thoroughly under running water and dry.

Disconnect the device from the network

Remove the tank and hose

Soak in a solution of citric acid for 30 minutes

Clean the walls and seals with a brush

Wash and dry all the details-->

3. Washing of pipes and hoses

This is the most painstaking part. Take a needleless syringe, put a cleaning solution (like hydrogen peroxide) in it, and slowly pass through the tube. Repeat 3-4 times, then rinse with clean water. For the best effect, you can leave the solution inside for 10 minutes.

If the tube is removable (as in Soocas) W3), Soak it completely in a soda solution for 20 minutes. Use a flexible brush brush to clean the bends (e.g., for bottles).

⚠️ Warning: Do not blow out the tubes with your mouth - this can cause bacteria from your mouth to enter the device.

Cleaning of nozzles and tips

Remove the tips and soak them in a chlorhexidine solution for 15 minutes. Use a toothpick (carefully!) or a special needle from the kit to clean the holes. Wash them under a stream of water and dry them.

In models with rotating nozzles (for example, Oclean X Pro) check the mobility of the elements – if they jam, lubricate with silicone lubrication (not technical Vaseline!).

💡

If the water stream is weaker after cleaning, check the filter at the pump inlet, which could have been clogged with plaque particles. In most Xiaomi models, it is under a removable mesh at the base of the tank.

How to Remove Mold and Bad Smell from an Irrigator

Mold in an irrigator is not only an aesthetic problem, it's a health risk. Fungal spores can cause allergic reactions and irritation of the mucosa. If you find black or green spots on the seals or walls, follow the following algorithm:

1. Mechanical cleaning: Remove visible mold colonies with a cotton swab dipped in hydrogen peroxide. Don't rub too hard -- spores can spread through the air.
2. Disinfection: Prepare a solution of 1 liter of water, 2 tbsp of hydrogen peroxide and 1 tbsp of soda. Pour into the tank and tubes, leave for 1 hour.
3. Ultrasonic processing (optional): if your model has an ultrasonic cleaning function (e.g. Soocas) H3), Turn it on for 5-10 minutes with disinfectant solution.
4. Drying: After washing, dry all the parts outdoors for at least 12 hours. Use a fan to speed up the process.

For mold prevention:

• 🌿 After each use, drain water from the tank and tubes.
• ☀️ Keep the irrigator in a dry, ventilated place (not in the bathroom!).
• 💊 Once a week, wash the system with a solution of chlorhexidine (0.05%).
• 🔄 Change the water in the tank every 3 days, even if you do not use the device.

Important: If the mold reappeared after a short time, check the seals tightness - they may accumulate moisture due to wear. In this case, replace the rubber rings (you can order them from official Xiaomi dealers).

Cleaning the heating element and pumps: instructions for advanced

If your irrigator model is equipped with a heating element (for example, Oclean X Pro Elite) or a pump, cleaning them requires special care. Incorrect actions can lead to the burning of the TEG or the failure of the pump.

Cleaning of the heating element

Scaling on the heater reduces its efficiency and increases its energy consumption.

1. Remove the tank and find the heating element (usually located at the bottom).
2. Prepare a solution of citric acid (30 g per 1 liter of water) and pour it into the tank so that the TEN is completely coated.
3. Turn the device on and activate the heating mode (if any) for 5-10 minutes.
4. Pour the solution, rinse the tank with clean water 2-3 times.

Cleaning the pump

In mechanical models (Xiaomi Mijia Portable), the pump can be clogged with plaque particles.

1. Disconnect the hose and remove the pump cover (usually it is attached to 2-3 screws).
2. Remove visible dirt with a soft brush. Use a toothpick dipped in alcohol (no higher than 70%) to clean the blades.
3. Blow the pump with compressed air (for example, a canister for cleaning equipment).
4. Lubricate the moving parts with silicone lubricant (1-2 drops).

⚠️ Warning: If the pump starts to work louder or if there are foreign sounds, immediately turn off the device. This may indicate moisture entering the bearings or wear of the blades.

Frequent Mistakes When Cleaning Xiaomi Irrigator and How to Avoid Them

Even experienced users sometimes make mistakes that cause the device to break down. TOP-5 most dangerous:

• 🔌 Cleaning a connected device is a risk of short circuit and electric shock. Always remove the plug from the plug!
• 🧼 Using undiluted vinegar corrodes plastic and rubber seals. Maximum concentration is 6%, diluted 1:1.
• 🔨 Mechanical cleaning with metal objects – scratches the internal surfaces, which accelerates re-contamination.
• 💦 Incomplete drying before assembly - leads to mold formation and corrosion of contacts.
• 🔄 Ignoring filter replacements in carbon filter models (Oclean) W10) They need to be changed every 3 months.

Another common mistake is using boiling water for disinfection. Most Xiaomi models have a maximum water temperature of 40 to 50.°C. Boiling water deforms plastic and damages electronics.

If you are in doubt, use official cleaning tools:

• 🧪 Oclean Cleaning Tablets - tablets for disinfection and plaque removal.
• 🧴 Soocas Cleaning Solution – a liquid for washing pipes.
• 🧽 Xiaomi Mijia Sterilization Box - ultrasonic box for sterilization of nozzles.

💡

Regular cleaning of irrigator extends its life by 1.5-2 times and reduces the risk of dental problems by 40% (according to the study of the Journal of Clinical Dentistry, 2022).
