Stainless Steel Construction: The chassis and body of the glass cleaner are made of electroplated stainless steel. The detachable 360° rotatable stand is made of thickened silicone material, which is heat-resistant and non-slip, effectively protecting your cup. High-Pressure Cleaning: The glass cleaner utilizes high-water pressure. The multi-angle rotating water jet thoroughly rinses away residue in seconds, while an overhang directs water flow into the sink for easy cleanup. Reaches Hard-to-Clean Areas: From baby bottles to wine glasses to travel mugs, it conveniently cleans all drinkware, saving you time on soaking and scrubbing. This handy and practical rinsing device increases the efficiency of daily cup cleaning. Multifunctional Use: Large enough to accommodate most glasses and cups (with a diameter less than 3.94 inches at the cup's mouth), including baby bottles, coffee mugs, wine glasses, champagne flutes, cups, cocktail shakers, jars, etc. Easy to Use: Gently press the bottom of the cup with the mouth facing down, and water will automatically spray to clean. After cleaning, remove the cup to stop the automatic water spray. Simple installation takes only 12-18 minutes.
