Is WD40 safe on plastic?

I have some tiny crystal balls like stuff on my air/radio display screen and need to remove them (Mine is base without Nav. This is where the navigation screen goes with Nav models)

It was there when I picked up the car from dealer and I guess this is some kind of hardened glue or something. I tried 303 but did not work.

I am thinking to try WD40 or Goo Gone but reluctant to do it because I don't want to ruin the plastic screen.

Are these safe on this plastic display cover? Or can Anyone suggest on how to remove these?

thanks

Got this straight from WD40's website. Hope it helps!

What surfaces or materials are OK to use WD-40 on?

WD-40 can be used on just about everything. It is safe for metal, rubber, wood and plastic. WD-40 can be applied to painted metal surfaces without harming the paint. Polycarbonate and clear polystyrene plastic are among the few surfaces on which to avoid using a petroleum-based product like WD-40.

So, is that display screen is made of "Polycarbonate and clear polystyrene plastic"???

Keep a microfiber cloth in the car, it takes the stuff right out.

How exactly? I used 303 and microfiber cloth but that did not work. So I've been thinking to use some other cleaner.
How do I use microfiber cloth to remove this stuff?

You need to identify what the spots are before you start using chemicals.....

Maybe this is a dumb question. How do I find what the spots are? I did not put it there and it was there from the dealer. Is there any way I can find it out?

I would opt for a very warm water moistened MF first.....Gently wipe. May take two applications, first application will soften it up for sure.
