Hi. A few months ago I prepared a pcb(H2O2 + HCl + Cu method) for my school project and afterwards I put it in the box where my other electronic equipments are standing. While ago I relaized all my equipments heavily smell acidic. I can't use any of my sensor cards, arduino boards, programmers etc. because after a short time, I feel burning sense in my eyes and lungs due to acidic smell. How do I get rid of this smell?
I already throw away pcb and changed box, I put all equipments on balcony and left them for days. I tried to clean them with wet fabric. Nothing worked. Can anyone help me with this?

Wash with a solution of sodium bicarbonate (baking soda) in water. Then rinse well with water. A tablespoon or two in a quart of warm water should suffice. If for some reason you can't use water, there are other possibilities alternatives.

Add Acetic Acid to get rid of acid??? No, just sodium bicarbonate and water for a washdown solution. For fumes/vapor just put sprinkle some bicarb on a plate near the source. Ummm... and this is a necropost...

RE:""How do I get rid of this smell?""
I would be more concerned how to get away those chemical rust imminent already soaked into Your sensor cards, arduino boards, programmers etc. Probably day long immersion into distillate may help? With sequential vacuum-drying.
 
Vinegar is very acidic and breaks down bacteria and absorbs smells, while charcoal absorbs odors well because it is very porous.
