The inside of a car's windows and windshields are just as worthy of a good cleaning as the outside, especially if your windshields fog up regularly. Fortunately a good cleaning is simple to achieve in just a few steps.

Tools Required

  • Extendable windshield reaching/cleaning tool
  • Microfiber cloths

Materials Required

  • Interior glass cleaner

For this project, grab two or more microfiber cloths, or a reversible cleaning cloth with a thick cleaning side and a fine drying side. You’ll also need a reaching tool with a curved head (optional), such as the Xindell extendable windshield reaching/cleaning tool with a 14-1/2-in. reach.

A good interior glass cleaner is essential. Choose a cleaner that’s safe for interior use, such as Meguiar’s Perfect Glass, to avoid exposure to chemicals like ammonia while inside your car. You can also make your own glass cleaner with equal parts distilled water and isopropyl alcohol, plus a capful of white vinegar.

Project step-by-step (5)

Step 1

Dry Wipe

  • Wipe the inside car windows with a dry microfiber cloth, working from top to bottom in an up-and-down motion.
    • Pro tip: Paper towels also work, but microfiber cloths won't leave pesky fibers behind on the glass.
      • This prep step removes that nearly invisible filmy layer of dirt and dust particles that stem from the plastic, vinyl and rubber inside the car.

Step 2

Add Cleaner

  • Spray the cleaning solution onto another microfiber cloth, a few spritzes at a time;
  • Avoid spraying the cleaner directly onto the glass;
    • Pro tip: Too much cleaner can make the glass hazy.

Step 3

Wipe On Cleaner

  • Rub the cleaner-dampened microfiber cloth in a circulation motion, again working from top to bottom.

Step 4

Don't Forget to Clean the Lower Spots

  • Use a reaching tool to reach the lower corners of the windshields.
    • These can be tricky and nearly impossible to reach — a tool here will help you avoid unnecessary gymnastics in the middle of your driveway.

Dry Glass
