Thank you. Around here, slag is what forms over the weld and has to be chipped off. I was referring to the white powdery coating that often surrounds a weld and is still there once the slag is chipped away. It can be brushed off, but it's hard to get to sometimes.

It's not galvanized. It was from stick rods. Lots of white flash that was hard to clean off the underbelly of this little guy. It's almost finished. I'll post more pics soon.

That might be the way. I was kind of hoping there's a spray or something that would dissolve it, but I do have an airbrush-sized blaster that could reach. It's a small area on a sculpture. Why didn't I think of that? Thank you!

Hello all. Does anyone have an idea on how to clean of the white flash left on steel by stick welding? Obviously a brush works, but it's in an area I can't reach. Thanks!
