There’s a spot on your car that you’ve probably been missing when it comes to cleaning. It’s not surprising, as it’s not immediately noticeable, but it’s actually one of the most important areas to clean: the tops of your windows.

When we say “the tops of your windows,” we’re not referring to the point where your windows meet the rubber seal on the frame. While it’s important to clean that area as well, we’re specifically talking about the rounded edges on top of the windows when they are rolled down.

Typically, when you clean your car’s windows, you spray both sides with glass cleaner and wipe them down with a cloth, right? However, if you only clean in this way, you’re only getting everything below the window tops. Any grime that has accumulated between the windows and the seal will remain untouched. On top of being unsightly, if it rains, all that grime will drip down and make your windows dirty again.

But don’t worry, this is an easy problem to fix. Simply remember to roll down your windows during your regular cleaning routine and give the tops a thorough wipe-down with glass cleaner and a rag. Make sure to add this step to your cleaning checklist!
