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

http://thinktink.com/stack/volumes/voliii/consumbl/devmix.htm

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.
