I do etch face up too. I don't use acid, I use a base. I get sodium hydroxide pellets off of Amazon (for soap making). Mix up a solution that is 40g in 100ml of water. It is slower and more controlled than acid. So I add it, go do something for 30-40min, come back and rinse it off. It doesn't give off fumes like the acid and to dispose Just rinse it down the drain, most drain cleaners are just sodium hydroxide solution.

I'm new to etching and totally in awe of the work of both of you. So far only tried some test etching using the salt water/electricity method with interesting results...
Question: when you say you etch face up, does this mean you just drip/dribble the acid/base on the design from above? Or do you mask off the rest of the enclosure and submerge the whole thing? Thanks.

Enclosure is face up and I pour on some ferric chloride and get the top of the enclosure covered. I use a chip brush to swirl it around a bit, add some more acid. When it starts to heat up too much I dunk it in a bin of water and let it cool down and then repeat the process till I think it's done. Ferric is pretty nasty stuff but I used to live a block away from radio shack and would just go and pick it up whenever I needed it.
Would like to try dminner's method with sodium hydroxide, though. Seems better for the health and environment!

Cool, thanks a lot. So do you need to cover the sides of the enclosure or isn't it an issue, acid running down the sides? I made a few boards back in the day with ferric so think I should be ok with that side of things.Would like to try dminner's method with sodium hydroxide, though.

Yeah, without sounding like a health and safety nerd, I'd be careful on the health side, that shit is nasty if you get it on your skin/in your eyes. But better for the environment though (hopefully, clears my drains brilliantly )
