While the glass guys were here installing the mirror, my husband, randy, got to chatting with them, as he usually does, about how their business was going. A thorough window cleaning is one of the more thankless tasks on the household chore list, but fortunately, it’s one you only have to complete a couple of times per year. It is easy to use and works quicker than most automotive glass cleaners on the market. Glass cleaners contain harsh cleansing agents such as ethylene glycol, ammonia, butane and others that can remove wax or any paint protection and strip the paint of your vehicle, causing it to yellow and cloud. Windex stood out as the best glass and window cleaner among the finalists we tested. Weiman is a foaming-spray cleaner that works great on stubborn messes, especially grease smears. We also encourage you to keep these and all cleaning products away from children and increase ventilation as much as possible while cleaning by opening windows and turning on fans. Which is to say, do not get this stuff in your eyes, nose, or mouth, and wear gloves if you have to clean more than one mirror or a few panes of glass, as it’s not great for your skin, either.
