Question about fixing a drafty window with spray foam I messed up today

I was sealing gaps around my basement window this morning and got the expanding foam everywhere. It dripped down onto the frame and hardened before I could wipe it. Now I got these ugly dried blobs on the wood. I tried scraping them off with a putty knife but it took the paint with it. Is there a trick to removing cured spray foam without ruining the surface underneath? Or do I just sand it down and repaint? I'm about 2 hours into this and the window still leaks air.

Honestly, you might be overthinking it. The paint was probably gonna peel anyway with that draft, so sanding it down and repainting is actually the cleanest fix. Scraping just makes a bigger mess, trust me I learned that the hard way too.

Wait, did you try sanding it with a finer grit first? In my experience, that draft makes the new paint bubble up if you don't get the old stuff off completely, so @blair_lewis85 is right that scraping is a pain - I'd just tack cloth it really good before you roll on the new coat.
