Well obviously I etch in my shed to avoid damaging my house carpet. but with subzero temperatures (naturally just at the weekends) I've found it impossible to etch, it just does not happen. now I did forget my presensitized board in the shed so will this have harmed it ? I developed the exposed board in fairly cold caustic soda, will this have been an issue ? I did have my etching chemical heated with a heater and after a few days the entire board was etched but I could not get it to etch there and then and it started to eat everything including the copper i needed to keep. the board was well exposed.
