Article: Hydrophobic coating makes water bead up and roll off your windows so you can see better during bad weather. Squeeze 23 dime-sized drops of the cleaner onto a foam applicator and spread it evenly across the surface with your finger. If you don't have a foam applicator, you can also use a short-pile microfiber cloth instead. You can buy hydrophobic coating and foam applicators from an automotive supply store. Try to find a starter kit that has both items if you're able to. Place the foam applicator against the top of the window and work toward the bottom. Move the applicator in tight, overlapping circles across the entire surface of the window so it has even coverage. If you notice that the hydrophobic coating isn't leaving any residue on the windshield, then put another 12 drops on the applicator before starting again. You do not need to apply a hydrophobic coating to your vehicle, but it offers an extra layer of protection so the glass is less likely to get damaged. Leave the coating on your window so it has time to dry completely. While it dries, apply the coating to your other windows so you can finish faster. Look closely at the coating to make sure it leaves a hazy appearance on your window, which means that the coating has set completely. Spray the glass with your automotive glass cleaner so it has even coverage on the surface. Use the long-pile cloth so you can lift up the most residue from the glass. Work in long back and forth strokes to lift up the coating and clean off the glass until it's clear. Repeat the process on the rest of your windows. Apply slight pressure while you're wiping the coating off so it lifts up easier.

What is a summary?
Wet a foam applicator pad with 23 squirts of hydrophobic coating. Apply the hydrophobic coating to 1 window at a time using circular motions. Let the coating dry for 510 minutes until it forms a hazy layer. Wipe off the coating with your glass cleaner and a long-pile microfiber towel.
