25 years ago the DND decided that soda blasters wouldl replace the sand blasters in Canadian service, and they made them available through the supply system along with the soda. The blaster they supplied was a wet soda type.... it combined the soda with water. It was touted as being more environmental and safer than sand.
So we ordered one in. I had been blasting several vehicles for an outdoor museum display, and so I gave it a try. Actually I gave it a very quick 5 minute try before putting it away and going back to the sand. I'll assume most other units did the same as I have not seen another nor heard of another in the 25 years since.
So while, to be honest, I did not give it a fair try, it got a thimbs down form me. Just the very thought of putting water on raw metal made me shudder.
Where I live now, I have scrub grass and about 6 inches of crappy soil with nothing underneath that but sand, sand and more sand. It is hard to beat free blasting medium, so I'll stick with it.
