Isn't it funny now to hear about 'back int days before paper towels folks used vinegar and newspaper to clean windows. Of course in those days newspaper (after it was read) could be used for fire startin, fish wrappin, and okay, windows. An vinegar is acidic and on hand so it could be used in place of some fancy cleaner...
(Newspaper is a poor choice nowadays because of environmentally friendly vegetable dyes that readily bleed away...onto your glass!)
I quite like Stoner's invisible glass and I'll use paper towels on the road but prefer a regular of MF towel when doing a detail. And don't forget to roll them windows down an inch or two to get the hidden part. Oh yeah and lets not forget some treatment like RainX or Aquapel at least for the windshield... This past week-end following a wash I slapped on another layer of DG AW and just for kicks, hit the side and rear glass with AW as well. Why I can see myself in that rear tinted glass <sheesh, I need to comb my hair and lose weight!>
