I use plates that wash out with water. And the special soft brush from boxcar press.  Boxcar press did carry the plates but may have stopped. 
They're good for 6 months. Or longer depending on storage temp.  

Never used any that needed soda ash? Or maybe I've been doing it wrong. :)

How many times you can use say a gallon of developer to develop 4x6" plates, before the developer is exhausted?
