I have a National Cycle Custom Heavy Duty windshield on my 85 VT700. I am wondering what other people use to clean their windshields. The instructions said to clean it with soap and water only. I find tha kind of hard to do on the road. I had a Windjammer fairing 20 some odd years ago and I used Novus #1  cleaner/polish with a non-woven cotton pad to clean both the body and the shield. I liked that product and it didn't take a lot so it lasted a long time and I liked the performance. My borther-in-law uses some spray can stuff from Harley but it is ungodly expensive. So what I am asking is what do you other windshield owner use to slean them with?
