If you’re like most people, you probably don’t know how to lubricate your windows. In fact, many people think it’s a dirty job that should only be done by professionals. But there’s a good reason why professional lubricants are so expensive and why many people don’t even know how to do it. Lubricants help keep your window glass clean and free from dirt, dust, and other debris. They also help keep your window open and allow the air to flow freely through the window. Lubricants can also be used on other parts of your home, such as door handles and hinges.
