Help me Fix slight overspray on window

[LEE-HO]

Can any body help me fix slight amount of over spray on the window of my BMAX4. The over spray is Tamiya PS-7 but is very slight in the centre where it got past my masking on the main window. I need the window to be clear, I need a easy fix for this problem, and still keep the window clear.

Panting the window out is not an option due to racing in BRCA events, the rest of the body is 100% perfect so would love to fix this over spray.

Thanks LEE-HO
