overspray removal

[70challengerrt]

I need a good way to remove overspray from seat covers. They are white I when I sprayed the dash black they got overspray even though I had them half way across the garage. I have used gojo and laquer thinner in the past but these are new covers.

Lacquer thinner will ruin the vinyl.  I'd try a little paint thinner on an inconspicuous spot and go gently and see if that does it. Good luck
