Heated Windows
Closed windows are very annoying, but you don’t want to see a mechanic. You can use shaving foam to degrease windows without leaving streaks on the glass. Apply an even layer to the inside of the window and wipe off with a cloth after a few minutes.
Defrost the windows
Frozen windows are difficult to melt, especially in the morning. If you don’t want to remove ice from your windows, you can make a vinegar solution using one part water and two parts vinegar. Spray it all over the window and watch the magic happen. However, the solution should be kept away from the car body as it can damage the paint.
