A All-Pro's Ultrasonic cleaning consists of millions of microscopic bubbles in warm detergent water that collapse at the rate of 50-300 cycles per second. This pulls the dirt, grime, or smoke away from the fabric, blinds and shades in seconds. Leaving them beautifully clean and NEW again. All of A ALL PRO'S Ultrasonic machines are specifically developed for our use in the Blind Cleaning Industry. The entire Shade/Blind is cleaned and Sanitized. The cords, gears, strings, fabric and the surfaces of the slats.
