Another thing about soda blasting. You don't have to degrease before you start. You don't have to do anything to the part. You can unbolt a nasty part from an engine or other component and put it straight in the blast cabinet dripping oil if you want. It comes out very clean in minimum time and does not mess up the blast cabinet. The soda mixes with the oil or grease and goes right out the bottom into the collector bucket. Or in the case of a hand held blaster right onto a throw away tarp. It want damage valve guides or seats. Actually makes anodized aluminum look and feel better. Those with restored Fuchs wheels that are anodized would find that soda blasting right on the car with the hand held blaster is the best way to clean them if they are beyond washing with soap and water.
It will strip paint. Also you would not want to try to clean a plastic part like tail light lenses.
Think of soda as "cleaning" as in parts washer cleaning but easier. Not as "stripping" as with bead blasting or sand blasting.
I haven't tried dry ice but am thinking that might be better than soda in that there is virtually no clean up to do on the blasted parts. However I am thinking that the equipment is probably to expensive for the home shop or small commercial shop.
