I am back to normal now. Acetone didn't remove my photo-resist I tried it. I have a negative photo-resist so I am trying sodium meta-silicate it looks to be taking awhile. Any other better ideas? I might go buy some polishing sandpaper soon.
Yet another reason to use a cheap prototyping service instead of home brew.
Why did you think acetone would remove it? Did you read how to use negative photoresist at all?
This is really useful for anyone who needs sodium carbonate just buy baking soda.
I use carby/throttle-body cleaner to remove the toner mask - works just as well as acetone but has a milder odour.
When you can get x5 10cm x 10cm boards with two layer, solder mask, silkscreen all for $10 there isnt any reason to make your own DIY pcbs.Unless you actually enjoy it, in that case etch away
Or do what everyone else does... outsource it to a third world country like China where the locals get poisoned at discount prices. What we should be doing is making PCB's in our own backyards or in our own cities. Home brew!
I do wish there was a list of PCB houses in china where they don't pollute and pay a fair wage.

And thats why im planning on making small plastic container with controller air draft to central air removal of house. Dont want nasty smells all over my home..
