Long story short: truck has been fixed and ready for p/u. Sat under oak trees for 2 years. Windows are a nice shade of green. Anyone know if vinegar is safe to use as a window cleaner? Safe on paint/rubber? Better alternatives that can be added to the wiper fluid (since I can't reach the windshield). Vinegar or just stick w/ wiper fluid? I'll have to get it clean enough to drive to a do it yourself carwash...
