Semiwave mode increases the peak power output (up to 900W) by delivering half-wave ultrasonic pulses, which generates stronger cavitation bursts — particularly effective for stubborn grease, carbon deposits, and tightly packed assemblies like auto parts and industrial hardware.\u003c\/p\u003e\n\u003ch4\u003eQ: Do I need to use a cleaning solution, or can I just use water?\u003c\/h4\u003e\n\u003cp\u003eA: Plain water works for basic cleaning, but using a compatible ultrasonic cleaning solution or diluted industrial degreaser significantly improves results for grease, flux, oxidation, and mineral deposits. The built-in heater (adjustable up to 80°C) further activates cleaning chemistry for faster and more thorough results.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this cleaner safe for PCBs and sensitive electronic components?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. When used with an appropriate PCB-safe cleaning fluid and the semiwave or lower power setting, this cleaner is well-suited for washing circuit boards. Always ensure components are fully dry before powering up any electronics after cleaning.\u003c\/p\u003e\n\u003ch4\u003eQ: What voltage does this unit support?\u003c\/h4\u003e\n\u003cp\u003eA: The Granbo 22L ultrasonic cleaner supports both 110V and 220V, making it compatible with standard outlets in North America, Europe, Asia, and other regions worldwide.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
