I use Pledge on my dirt bikes and it works great. But, I have found after using it on goggles visors and windshields that is leaves a minor residue. This can be annoying in the sun.
I started using Plexus on my optics and wow, what a difference, nice and clear. They designed Plexus to use on Lexan Race car windshields and aircraft windshields, so I now use it on all my shields and well worth the money. No residue at all and after you give it a little buff job after application, nice and clear. The bugs clean off easier too.
Pledge is ok and I used it for years, until Plexus came into my life...
