i am looking for suggestions on what to use and/or what not to use on face shileds?  i have an arai original face shield if that matters.  i'm trying to avoid the trial and error route since i can't afford a new shield if i hit the error part first.   i've found on the web all kinds of people for and against rain-x, some have said to use pledge.  i need product advice.

thanks,

I used Pledge, it's ok, but not great, Rain-x is better on the windshield of my car. I have heard that it is the volatile solvent in Rain-X that causes the windshield to crack, so, in theory, if you let it dry a on a rag before applying, it should be safe, but I have not dared to try.
Better is Maguair's (sp?) 17 followed by 10 (or is it 10 followed by 17?). I use them to remove hairline scratches. They work well also for rain.

I use Meguire's liquid car wax.  #3 or their 3-part combination.  Works quite well.

I don't use anything. What exactly are you asking for? Are you looking for a de-fogger to be used on the inside? Or just a wax, or something like Rain-X to keep the rain off, for the outside?

De-fogger - I've heard of using gel type toothpaste like clear green, minty fresh Crest...Not Colgate though, I heard that's too abrasive; But I've never tried this.

Otherwise, I just use a 100% white cotton shirt and breathe on the faceshield to fog it up and wipe both the in and outside.

Ah, after I posted I read your title. A little trick I use is to turn my head a little to one side and let the wind roll the water off the shield, then the other side.

RainX works very well, but doesn't last long on a face shield. I used it four or five times on one, and didn't see any change in the shield.
