If this is what the vehicle will look like...

As I look at the amount of glass, solar reflective glass on this planned new version of the Aptera.... I can share the following:

I have a vehicle with nearly as much glass. I have found a green product for glass that has made my life easy with cleaning glass... and you only need water! 

I use for my huge windows at home too

I have found nothing that is perfect but.... this was a game changer for me.

The way I handle my vehicle cleaning 

I power wash the entire vehicle with water only. 

In the shade on a cool window...

I wipe the residual water off with a soft old bath towel

I dampen the *Spiff Cloth as recommended, squeezing out the excess water, and clean the glass.

Keeping it green and easy...

✅No product spray

✅No premature drying of product on glass on hot or windy days, (as I can re dampen the cloth)

I use well water or filtered water from my roof water capture tank

I suppose (RO) Reverse Osmosis 💦 may be interesting  to try....as that can cut through light oily fingerprints, etc

*This is a reusable cloth, not like paper towels. But they have  to be replaced eventually. 

I gave one Spiff cloth to my neighbor who has a 700 glass panel greenhouse😔.... She became a believer
