Homebrew PCBs

Thanks for you replies. I meant to include the units - I'm operating in Celsius degrees. 

Could you provide me an idea of what reasonable concentrations of HCL h202 might be? I would be using the low strength peroxide and building boards of no greater than 4" by 4".

My worry is that the corrosive fumes from etching and storage will pose a hazard to anyone sleeping in the bedroom above the garage and to any metal, like my car, stored in the garage. 

Is anyone else in the same predicament as me?
