Operating Instructions
The EcoBasic Ultrasonic Retainer Cleaner features a single-button control for ease of use and offers four professional cleaning modes:
- Mode 1 (Green light is on): 5 minutes ultrasonic with UV light for daily quick cleaning.
- Mode 2 (Red light is on): 10 minutes pulse ultrasonic with UV light for stubborn buildup and deep cleaning.
- Mode 3 (Blue light is on): 10 minutes ultrasonic only, suitable for delicate items.
- Mode 4 (Green, Red, & Blue indicators light up at the same time): 10 minutes UV only.
To select a mode, press the power button repeatedly until the desired light indicator appears. The digital display will show the remaining cleaning time. For items with heavy stains or buildup, it is recommended to use Mode 2 or Mode 3 for 2-3 cycles. To turn off the device before a cycle completes, press the power button 5 times.

Maintenance
After each cleaning cycle, carefully pour out the water from the tank. Wipe the stainless steel tank and the exterior of the device with a soft, dry cloth. Do not immerse the main unit of the cleaner in water or rinse it under running water, as this may damage the electronic components. Ensure the device is completely dry before storing.
Troubleshooting
- Device not turning on: Ensure the power adapter is securely connected to both the device and a working electrical outlet.
- Poor cleaning results: Verify that the water level is correct (up to the MAX line). Consider using a cleaning tablet. Try a different cleaning mode or run the cycle 2-3 times for heavily soiled items.
- Unusual noise during operation: Some vibration and a high-pitched sound are normal during ultrasonic cleaning. Ensure the device is placed on a stable, flat surface to minimize excessive noise.
