Quick question about a cpi replacement!!!

I started a few hours ago replacing the cpi, and nut kit, everything is going great. What is the best way to clean all that gas and gunk out from the plenum where the regulator was leaking. Or should i just soak up the gas and leave it?? Thanks everyone for all your help. For anyone thats looking for a how/to BlazerLT pointed me to this site:

Thanks Blazer!

I would try methol hydrate or rubbing alcohol first, and if that doesn't work try using a mild engine cleaner like gunk
