My regulator had rust dust in the screen, hoses and everywhere else, and so did my BC, requiring them to get rebuilt a little early. The shop said my tank needed a tumble and a hydro. I took it to another shop that takes care of my tanks and they did a visual on the tank. They found about a teaspoon of powdered rust in the tank, but the tank was not rusty! They suspect I got it from a air fill. I've been using this shop for years for air fills, but spent a few days in Monterey a couple of months ago. That is where they think I got the rust from. Anyone else have this happen to them? I don't want to point fingers because I used all three shops in Monterey to get air fills. (I live in San Jose so normally I just go for the day and fill locally.) I checked the powder with a magnet; it's all rust.
