No need to clean freshly blasted metal. Blow it off with compressed air and shoot your epoxy primer. If you can't live with that then wash it with water and Dawn dish soap. Blow dry with a leaf blower. No need for anything more imho.

Depends on humidity but no amount of cleaning will stop it from flash rusting in high humidity. If you are short if time skip the washing and use the time to epoxy prime it.
I am guessing your car will never see rain let alone road salt again. Don't over think this stuff. Get at it, get it done and enjoy driving your car sooner....

I've had parts of my car in bare metal for years in a sometimes heated garage. I use a ventless furnace when I do heat which supposedly adds moisture to the air. In the last year I've started to see surface rusting begin. I'll reblast those panels before I prime. I really think Don is right, Blast it, squirt primer and paint on it and go. Highly unlikely that it will ever need redone in your lifetime.

Follow what the paint manufacturers recommend.
I am using PPG paints. They recommend that no further metal treatment is needed after sandblasting. Just clean with a wax and grease remover (DX 330) after sandblasting and prime with an epoxy primer. PPG recommends to apply primer paint within 12 hours after sandblasting. I am paraphrasing PPG TD004 technical bulletin.

I learned that paper towels or the blue paper towels seem to tear when I wipe down metal that is freshly sandblasted with DX 330. I use a white terry cloth now.

Rub down with a scotch bright pad, blow dry, mineral spirits, prime.

I'm going to suggest a proper wax and grease remover versus mineral spirits.

If its body panel I'd do like 327fuelinjected says.
On a subframe, just give it a good going over with 150-psi and epoxy primer it.
I went through 5 Navy Ship Yard Overhauls where they blasted the ships hull with 80 grit Black Beauty Abrasive, air cleaned it, applied Zinc Chromate, Epoxy, then Hull Black Or Navy Gray. The paint underwater fared well for 8 years

Blast, blow, epoxy, done deal. A professional, clean air filtration system is all you need. If flash rust is evident then re-blast. Mineral spirits has no place as a W&G remover in a professional shop. The OP should have mentioned what grit media he chose. 0,00,000. Triple will barely affect a quality, lint free rag. You should be stocking a box of them for your resto.
If you are using PPG products you may want to check into the Commercial or Vibrance line and talk to your rep who has a clue. Call the PPG tech line if needed. CRE and VP 2050 are nearly the same and will save you considerable time in blocking and procedures. They never get any mention on hobby sites.

Read a tech sheet for a chosen Z C., and the epoxy within the same company in the automotive repair industry.
