I have only used the EZ2CY cleaner polish with great results. Why use anything else. BTW, use of Pledge especially long term may create problems. The marina we were once at recommended it to use on the curtain vinyls, and there was a rash of browning, hazing and cracking of the clear panels after a year. Was it the Pledge? Don't know for sure.
My understanding is that these products, EZ2CY, IMAR, etc., have ingredients designed for clear panel use, platicizers, etc. I use IMAR on our Strataglass and EZ2CY products on the EZ2CY panels. After 4 years, our panels are still almost like new.
