How to clean HUD projection screen

[TallGuy]

Have a 2016 A6 Prestige. Notice some dust and a couple of spots on the reflective surface of the HUD that projects onto the screen.
What type of cleaner may be used on this?
Thanks

Sorry there hasn't been much attention to this. I personally don't have that and had no idea what it was made out of. A quick google search on the tech brought up a description of it on Audi's site that states, "A TFT liquid crystal display backlit by a white LED generates the color image. Two aspherical mirrors enlarge it and redirect it while compensating for the distortion caused by the shape of the windshield." Presuming that's what we're talking about here, a clean MicroFiber cloth and my favorite all-around safe cleaning mixture of 10:1 Water:Woolite will do the trick on both the TFT display and the mirrors. Stoner's Invisible Glass should work equally well (or even better) on both as well.

Thank you for your response. Prior to hearing from you I gingerly use Stoner's on it with a microfiber cloth. Seemed to work without a hitch. What have you used on other plastic display screens?

Office Depot sells screen cleaners for LCD displays also.

I only use what I've suggested above. I clean my TFT MMI display with either of the two, depending what's in my hand.

Thanks, I will give the Stoner's a gentle try.

Stoner is pretty good stuff.
