I just had a new windshield installed, and previously I'd been using a product from sportys for cleaning plastic. A pilot at the hangar told me its better to use water and a soft cloth versus using chemicals. This is the first time I've heard of this and I wanted to hear from other owners what they use on their windshields? I've heard of everything from lemon pledge to special moist wipes to clean the windshield. Should I just be using water and a soft cloth instead of chemicals? Looking forward to hearing what others use.. Thanks!
