1. Why Internal Cleaning Is Essential

While the ultrasonic sink cleans your items, contaminants like grease, limescale, and bacteria can build up inside the tank. This may result in:

Reduced cleaning efficiency due to impaired ultrasonic wave transmission.

Unpleasant odors caused by bacterial growth in residual water.

Mineral deposits from hard water, potentially damaging the transducer. 

Stains and residue that affect cleanliness and appearance. 

Regular cleaning prevents these issues and ensures consistent performance.

2. Step-by-Step Deep Cleaning Process

Step 1: Empty and Rinse the Tank

Unplug the ultrasonic sink and drain all liquid. 

Rinse the tank thoroughly with warm water to remove loose debris. 

Step 2: Prepare a Natural Cleaning Solution 

For Descaling: Mix 1 part white vinegar with 3 parts distilled water. 

For Degreasing: Add a few drops of mild dish soap to warm water.

For Stubborn Stains: Use a citric acid solution (1 tablespoon per liter of water). 

Step 3: Run an Ultrasonic Cleaning Cycle

Fill the tank with your chosen cleaning solution. 

Run the ultrasonic sink for 5–10 minutes to loosen deposits and disinfect the interior.

Drain the solution and rinse the tank thoroughly with clean water.

Step 4: Clean the Transducer and Tank Walls

Gently wipe the transducer plate at the bottom with a soft, damp cloth. Avoid abrasive tools. 

For mineral buildup on the transducer, place a vinegar-soaked cloth on it for 10 minutes before wiping.

Use a soft sponge to clean the tank walls if needed.

Step 5: Dry Thoroughly

Wipe the tank and lid with a microfiber cloth.

Leave the lid open to air-dry completely before reuse.

3. Maintenance Tips for Optimal Performance

✅ After Each Use: Rinse the tank with distilled water to prevent residue buildup.

✅ Weekly Cleaning: Run a vinegar-based descaling cycle to remove limescale.

✅ Monthly Inspection: Check for mineral deposits, corrosion, or transducer damage.

❌ Avoid: Harsh chemicals (e.g., bleach, ammonia) or abrasive scrubbers that can damage the tank.

4. Troubleshooting Common Issues

Problem Solution

Cloudy Water: Use distilled water instead of tap water to minimize mineral content.

Weak Cleaning Power: Descale the transducer and tank; ensure water covers the transducer.

Persistent Odors: Run a cleaning cycle with baking soda or citric acid solution.

Stubborn Stains: Gently scrub with a soft brush and mild soap, then rinse thoroughly.

5. Safety Precautions

⚠️ Always unplug the unit before cleaning to prevent electrical hazards.

⚠️ Never immerse the power unit or controls in water.

⚠️ Use only non-abrasive tools (e.g., soft cloths, sponges) to avoid scratching the tank.

⚠️ Ensure the sink is fully dry before plugging it back in.

Conclusion

Regular cleaning and maintenance are crucial for keeping your ultrasonic sink efficient, hygienic, and durable. By incorporating these simple steps into your routine, you can extend the lifespan of your appliance and ensure it continues to deliver optimal cleaning results. A well-maintained ultrasonic sink is a reliable partner for all your cleaning needs!
