Well I finally had a chance to try out the cheap soda blaster on my BMW. Went to Smart and Final bought a large 5 pound plastic container of baking soda for $3.29. Cut a small x in the tiop and inserted hose. WOW, cleaned all the accumilated gunk off the hubs, cleaned off the rusty spokes, engine sides and carburators. Cleaned everthing I could find. Gave a nice satin finish to the aluminum, does not seem to hurt anything as it is not too agressive. Even when it hits you in the face not bad, tastes OK. Easy clean up with water, everything just washes away and dissapears.
I have included the link to the idea, air gun avaialble from Habor Freight for about $5.00, I was pleasantly surprised how well it worked.
