Chemical before WFP?

I am newly registered here but have been reading for a few months and have learned a lot and thank you! I started with a DI tank but was going through the resin too fast with TDS of about 250 in most of my area. I bought an RO system online for about $550 that puts out about half a gallon per minute which I then run it through the DI tank and is the perfect amount of pressure for WFP.

I generally pre-wash the windows with a vinegar and water on a t-bar and pad first to make sure I get all the corners and loosen up all the gunk. It works quite well and makes the brush glide across the windows and rinse like a dream!

Does anyone else use anything to pre-wash the windows?
