Blind Cleaning Experts Ltd. uses the latest technology with environmentally safe, biodegradable cleaning agents to create the most positive cleaning force in today's society - and for the future. The Ultrasonic process creates millions of microscopic bubbles which form repeatedly and implode on a given surface. This powerful action removes visible and even microscopic dirt particles. Use of this technology will dramatically reduce/eliminate germs, pet dander, pollen, dust mites, nicotine and all other allergy contributors making a healthier home for your family or workplace for your staff. Blinds are pre cleaned/treated before being Ultrasonic Cleaned. The Ultrasonic process can remove build-up of dirt, nicotine, grease or soot. Hard-to-clean areas such as the headrail, cords and ladders also become clean, adding longevity of use and luster to the blind.
