The inside of the windshield of my 1995 Honda (also my 1992 Honda) will
 

fog up easily. How to stop? I've noticed especially on rainy days that the inside of my front windshield will fog up and it's almost impossible to get rid of without putting the heat on full blast. Any suggestions?

Turn on the AC and set it to defrost. It dehumidifies the air. There's no need to turn the heat up (just set the temp dial to a comfortable setting).

my car does this as well....especially on rainy days.....the best solution is the air con....clears it in about 40 seconds or so
