There's zero residue left behind.....unless you're talking about wet soda blasting. I do it dry with a hand held gun, blow it off and prime and paint it. Just that quick.
Thanks I just got off the phone with my local guy who I thought used soda but he told me he uses ground glass, he said basically all one needs to do is wipe it down with a pre-cleaner and epoxy prime it, and what makes it even better he is less than half the price of dustless blasting
