Check out the developing and striping solutions you can mix up on Think 
and Tinker's website:

The Soda Ash mentioned is the same as Washing Soda (sodium carbonate 
monohydrate) that can be picked up in your local grocery store in the 
laundry section, it is a common soap used to clean clothes and fairly 
beign.

The Sodium Hydoxide is of course Lye, which is often found in the drain 
cleaner section (you want pure Sodium Hydoxide, not mixed with any 
thing else). Lye is more damaging and should be treated with 
appropriate care. (Gloves, safety glasses, plenty of ventalation, plus 
always add the lie to the water, not the other way around).

They also give you the concentrations normally used to develop and 
strip the the boards.
