It would offer the control of only stripping what you want to strip and there would be no toxic leftovers for the process.
I've read a little on this, and also using wheat starch as blasting media. I ran across it a while back and found it in some military aircraft stripping studies where they were determining the environmental impacts of various stripping methods. I'll see if I can run down the link and post it here.
Thing is, I don't know where you could buy enough starch or soda in bulk to do the job. Given a choice between the two I think I'd pick the starch over the soda - since I'd be doing this outdoors I don't know what the soda would do to the acidity of the soil in my yard - would hate to kill all the grass.
