Spilled nail polish remover on my iPhone?

I spilled nail polish remover on my iPhone this morning. It now has a black splotch on the screen, but the phone is now dry and still functioning properly. Is teen works perfectly fine, speakers work fine, seemingly everything is okay.

The nail polish has acetone. What will this do to my phone? And how long will the effects of the acetone take place?

Probably nothing if it didn't already happen. Glass is rather tough.

Same thing happened to me did the black splotch come out. (sorry not really helpful, just want to know)!
