Soda blaster

I have one that was given to me.

Make sure that you have a dry air supply, so the soda doesn't clump up & plug the hose.

Once you clean a part, if your going to paint the part you need to dip the part in Vinegar as the soda will cause the paint not to stick very well. (Found out the hard way) Newmann can better explain the chemical process.

From what I understand there different grades of Soda for different type of jobs. fine to course.

As far as cleaning Concrete & walkways, your better off with a Power washer/ chemical cleaner - Much cheaper!

Some of those tasks would require a really large system, what are you looking at?

I know right! One bottle at a time would take forever.

I recommend using industrial grade soda for removing anodized or spray finishes.
