Professional window cleaners typically recommend that homeowners have their windows cleaned every two to three months. This interval ensures that your windows will stay clean and streak-free, but it also allows for any build-up of dirt, pollen, and other debris to be removed before it has a chance to cause permanent damage. For example, if you live in a dusty location with particularly large windows, you may need to have them cleaned more often. However, as a general rule, cleaning your windows every two to three months is a good way to keep them looking their best.
