C Liner Material: SUS304 Stainless Steel Shell Material: Stainless Steel Basket: Equipped Sound Reduction Cover: Equipped FAQ: Q: What is an ultrasonic cleaner? A: Ultrasonic cleaning is based on the cavitation effect caused by high frequency ultrasonic wave vibration signal in the fluid. Microscopic bubbles are formed, and then implode violently causing the cavitation which create an intense scrubbing action on the surface of the item being cleaned. The bubbles are small enough to penetrate microscopic crevices, cleaning them thoroughly and consistently. Q: Which products can this ultrasonic cleaner cleaning? A: Many products can be cleaned. Common such as glasses, necklaces, earrings, bracelets, electronics, watches, dentures, printer ink heads, razor heads, nibs, coins, badges, pacifiers, etc. Q: Which builders can be properly added for better cleaning during the cleaning process? A: You can add cleaning liquid or detergent, such as: dish detergent, soapy water, disinfectant, etc., but do not add acidic or alkaline solution to the machine to prevent ABS corrosion damage. Operation process: 1. After unpacking, shake the machine slightly and listen to the sound in the chassis to confirm whether the parts are loose. 2. Place the machine in a ventilated and dry place to ensure that the machine is in a horizontal position; 3. Add an appropriate amount of cleaning solution (2/3 groove depth
