I keep several small squirt bottles of eye glass cleaner in the garage by my riding glasses and helmets. I use the stuff given to me at eye appointments or cheap Walmart refill bottles. For years I've used the same eye glass cleaner on my face shields and glasses to make fast work of bug rehydration and easy thumbnail scraping and cleaning. But being old and set in my ways i kept using soap and water to rehydrate bugs on motorcycle windscreen... UNTIL THIS PAST SUMMER. Never again. I finally developed a thought that the solution that has worked so well on glasses and plastic face shields might also work great on plastic windscreens. It does... faster and cleaner. Why did it take me so long to do this?
