This is a proven window cleaning technique that offers the best possible results. Unlike those using a waterfed brush system our cleaners are able to make a close inspection of all windows once finished. This reduces the risk of any marks being left by accident. To find out more on the benefits of this method over the waterfed brush system, for window cleaning, please take a look at our FAQ section. Cleaners apply a mix of water and detergent to windows using specially designed applicators. A rubber squeegee is then used to remove all water and detergent.
