It works much better than my previous favorite product for rain, Pledge. This does not leave an oil film like Pledge and some other products do. It makes rain bead up and roll off your windshield. It was developed for the US Military for aviation window maintenance.
Plexus is fast, easy and effective.
Spray on and wipe off. It cleans without abrasives, ammonia, alcohol, or other harsh substances that can harm our plastics. Plexus leaves a dry, micro thin protective layer that helps resist fingerprints, scratches, yellowing and makes fine scratches less visible. I found that after use it is easier to clean and the anti-static properties keep the plastic cleaner longer. I use it mostly on my windshield, helmet visors and glasses, but the best part is that it can also be used on all of the other plastic parts as well as chrome.
