If you’re like most people, you probably cringe when you see film or dust on your windows. But before you reach for the vacuum cleaner, there are a few things you can do to clean them yourself. The first step is to use a cloth or paper towel to gently wipe the surface of the window clean. Make sure to get into all the nooks and crannies. If there’s still film or dust on the surface, use a microfiber cloth or a piece of paper towel dampened with water to wipe it off. If using water doesn’t work, try using a mild cleaner such as dishwashing liquid or rubbing alcohol. Be careful not to damage the window glass with too much pressure or scrubbing. Just wet the cloth and wipe away any dirt or film. ..
