6. Degassing Mode
The 600-second cleaning mode on the Hogance SJ-H2 is a specialized degassing mode. This mode operates intermittently to extract dissolved air from the cleaning liquid. By creating a near-vacuum state through the circulation of water molecules, it allows the ultrasonic waves to be more effective, leading to improved stain removal and overall cleaning performance. This advanced feature, previously common in industrial ultrasonic cleaners, is now available in your household unit for superior results.
7. Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your sonic cleaner:
- After Each Use: Always unplug the unit and empty the water from the tank.
- Cleaning the Tank: Wipe the 304 stainless steel tank with a soft cloth. For stubborn residue, use a mild detergent and rinse thoroughly. Do not use abrasive cleaners or steel wool.
- Cleaning the Exterior: Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals.
- Storage: Ensure the unit is completely dry before storing. Store in a cool, dry place. The removable lid and detachable power cord facilitate easy cleaning and storage.
- Water Quality: Using distilled or demineralized water can help prevent mineral buildup in the tank, especially in areas with hard water.
