What is your favorite glass cleaner for cleaning your car?

I use my standard 'cleaner for everything non-porous'. Namely, 1 part white vinegar, 3 parts water, and 1 drop of dish soap, (optional 1 drop peppermint oil) in a spritz bottle. Works great, and cheap.

 

Could be calcium deposits from the water. I had this on a previous car and nothing would remove them, until I tried Griot's Garage fine glass polish:

Sprayway - it looks like something from the 50's but it cleans really well. I get it at Publix supemarket. Zaino makes a glass polish that makes the glass really smooth. It's not something I use daily or weekly, but every couple of months or so.

 

I've tried many things through the years but works best for me is the real chamios that I use to dry the outside. Pulls off everything and doesn't streak.

 

Sprayway. Blue and white can, soft microfibre towel.

 

Vinigar helped and then a big dose of Rainx.
