Metal cleaning after sandblasting

[oilboy123]

Had some open channel and 3x3 steel tubing sandblasted. It was galvanized metal on a boat trailer.

What is recommended for cleaning steel after sandblasting? I was thinking air blast the metal then solvent wipe, or hot soap and water? But I would be concerned about rust?

Solvent clean with some prep sol, or acryliclean. And paint asap.

No water.

^^^ what Jake said. If you want to take it a step further, give the surface a phosphate treatment. Chemicals are available from your local paint shop supply house.

What would be best to use as wiping rags? My concern is lint left on the metal after wiping because it's got tooth after the sandblast.

We sandblast every single day...Don't wipe with anything, man!
You have a compressor, so use air..you can get filters for the very tip from paintshops that stop water/oil.
Lacking that, use a new china-bristle brush.
Paint NOW or rust starts fast, due to the peaks/valleys...

+1 do not wipe no need blow off and prime right away. I never touch a thing after sandblasting just paint.
