Ohhhh so you basically use the draft to sandblast the boiler from the inside 😮

I remember asking a guy who was knowledgeable about steam locomotives this question many years ago and he didn't know the answer. I wondered about it for a long time.

I didn't even know you put sand in there to begin with...

[@Grantiese]

im guessing it cleans out the tubes and stack

[@1940limited]

That's what I thought.
