Let me start by stating that Plexius is a great product, have used it for years with great results. But at $16.99 per 16oz can I had to question how much I was using and if there was not an equal and cheaper alternative. Before finding Plexius, many years ago, I was using Pledge furniture polish and was still using it for detailing bikes and cars, but not on the wind screens and visors. Well after some experimenting I can report that Pledge works great and it is actually hard to tell the difference in the results. Pledge at my local grocery store is cheap, purchased 3 - 16oz cans on sale for $5.00 ($1.67 per can). One-tenth of the price of Plexius is hard to ignore.
