Primer stripping

Hey all... stupidly did not check weather and humidity was way higher than expected and ended getting really sandy priming.

I have 99% isopropyl alcohol, but also hear tell of Simple Green. I have extra sprue to test with, but my question is thus....

Which simple green to get? I dont want scented, i know that, just different additives. But i see foaming, all purpose, all purpose concentrate.

Help appreciated, Thank you
