Sorry for delay in replying, had to go out for a while, but i see your question was answered perfectly well, i also use "Chiltern Connections Ltd" [UK company] PCB photoresist developer which is a sodium hydroxide free product, code: CCL/PDSM/25B their contact number in UK is +44 1491 824788 FAX +44 1491 824799. not sure if its available in the US though, its main ingredient is Sodium metasilicate works perfectly well, as does the developer from the ebay dry film supplier.
