1. Product Overview
The CREWORKS B0D312RZSV Ultrasonic Cleaner Kit includes a 2L Professional Ultrasonic Cleaner Machine with Heater and Timer, and a 200ml Ultrasonic Retainer Cleaner Machine. These devices utilize ultrasonic cavitation to provide thorough and professional cleaning for a wide range of items, from delicate jewelry to household items and dental appliances. The cavitation effect generates microscopic bubbles that implode, creating a scrubbing action that effectively removes dirt, grime, tarnish, and other contaminants without harsh chemicals or radiation.

4. Setup and Operation (2L Cleaner)
- Prepare the Unit: Remove the lid and the basket from the tank.
- Fill the Tank: Fill the tank with water and an appropriate cleaning solution (e.g., regular dish detergent for general cleaning, or a specialized ultrasonic cleaning fluid for enhanced cleaning). Ensure the water level does not exceed the maximum fill line indicated inside the tank.
- Place Items: Gently place the items to be cleaned into the basket. Ensure items are not overloaded and do not directly touch the bottom of the tank.
- Replace Lid: Carefully place the lid back onto the unit.
- Power On: Plug the power cord into an outlet and turn on the main power switch located at the back of the unit.
- Adjust Settings: Use the control panel to set the desired temperature and cleaning time according to the cleaning guidelines below.
- Start Cleaning: Press the oscillator button to begin the ultrasonic cleaning process.
- Monitor and Stop: The unit will automatically stop the ultrasonic cleaning when the timer counts down to zero. To stop heating, manually press the heating on/off button.
- Cool Down and Drain: Allow the water to cool down before draining. Use the drain valve on the side of the unit to easily empty the liquid into a sink or appropriate container.
5. Cleaning Guidelines (2L Cleaner)
Optimal cleaning results depend on the type of item and the level of dirt. Refer to the following guidelines:
- General Cleaning (Lightly Soiled Items): For items with light dirt or tarnish, use water with a regular detergent. Set the temperature to approximately 120°F (49°C).
- Enhanced Cleaning (Deeper Cleaning): For items requiring a more thorough clean, use a fluid specifically designed for ultrasonic cleaners. Set the temperature to approximately 140°F (60°C).
- Extensive Cleaning (Heavy Deposits): For items with rust, fuel residues, or hard carbon deposits, pre-soak the item before cleaning. Use a specialized ultrasonic cleaning fluid and set the temperature to the maximum of 176°F (80°C).
6. Mini Ultrasonic Retainer Cleaner (200ml)
The kit also includes a compact 200ml ultrasonic cleaner, ideal for delicate items like dental appliances and small jewelry. It features 24W ultrasonic power and operates at a 46 kHz frequency, ensuring gentle yet thorough cleaning. This mini cleaner also incorporates UVC cleaning for enhanced sanitization.
