   The reflection off the INSIDE of the window (resembling clear    
   finger-paint patterns) from direct sunlight coupled with the fog from my   
   breath inside the window (22F outside when I went skiing yesterday, a    
   thing I would normally be really happy about) made the road invisible. I   
   grabbed a hand towel to clear the fog before the heater (which makes the   
   car too hot -- the dribble of warm air from the vents keeps me comfy    
   warm) blew the fog away.  The sun is now an hour lower due to DST :-(   
      
   Today I have cleaned the windshield with the following in rapid succession:   
      
   Windex   
   Bargain general-purpose cleaner which does a fine job on other stuff.   
   70% alcohol with paper towels   
   Trader Joe general purpose cleaner (sage and something, it smells REALLY   
   good)   
   	 and a clean flour-sack dishtowel   
   25% Dawn in water   
   91% alcohol with toilet paper   
      
   The oil-like residue is still there.  Now I'm wondering about spray    
   gunk.  And possibly engine cleaner.  I've got a LOT of spray engine    
   cleaner...   
      
   --    
   Cheers, Bev
