There are various course of sand to blast with. Best ones are the silica sand that is used in pool filters. However, be sure to wear a mask if you are using silica sand. I have used regular river sand to remove paint from a car.
I've even used regular play sand. It needs to be good and dry however. Again, it depends on what your blasting. If you can capture and reuse, then one of the mediums is best, but if your doing something like a trailer frame, then sand may be cheapest.
Thank you all for your replies.
I have nothing specific in mind to clean but I would use it around the shop for planes and other tools and also for trailer frames and the like.
I think that it would handy to have around.
I have a 2HP/21 Gallons air compressor, how much this thing uses?
