It took us a long time but we've finally found a scheme for washing the HOUSE windows (lots of glass, here) without streaking, lint, etc.
But, no such luck with the car. *Any* car! Windshields are always a chore cuz of the low attack angle (can't get to the glass as it nears the dashboard). Other windows are too small/odd shaped for a squeegee.
And, of course, you never know if you've done a good-enough job until you get the car out in the sun and try to SEE through all your invisible smudges! :<
Presently using "Invisible Glass" which *seems* to do a good job but ONLY if you diligently remove ALL traces before it dries.
Next time, I'll try the stuff we use on the house windows (pour some of it into a spray bottle). Maybe see if I can find a TINY squeegee with which to apply it; virgin newsprint to dry.
Anyone have any secret (cleaning) solutions or techniques?
