If you bought cooking grade soda, you would spend about as much on soda as someone would charge you to do the job professionally. I went to Smart and Final and bought a couple of 5 lb. jars of the stuff. It's expensive when you buy it in quantity. I think commercial soda is much cheaper, but I don't now where to buy it.

And, it makes one heck of a mess. I did some soda out in the back yard and the place looked like I was burning weeds. However, the vacuum plugs up pretty fast with such a fine medium.
