The last time we covered metal etching, a few folks commented that it was too dangerous and asked if there was a safer way to etch metal. Oh my, did they educate me! I asked if anyone had experience with a safe or at least less dangerous, nontoxic way to etch metal, maybe using household items that seemed like they might work, such as lemon juice, nail polish remover, or a mixture of vinegar plus something —that always seems to be a handy household combo that can work wonders, so I thought it might be worth a try.

You must dispose of the spent metal etching solutions at a hazardous waste site. This is the big reminder I got from our discussion that I often forget: Etching removes small particles of metal, just like sawing and filing do.
So where does that metal go? The solution you use—toxic or not—is ultimately going to end up full of tiny particles of whatever metal you etched.
You can strain the particles from the liquid with a coffee filter, or allow the neutralized liquid to evaporate from the solution, leaving just the dry metal dust remains. Update: Allowing the liquid to evaporate is the better of the two solutions, because not every tiny particle of metal can be removed with a coffee filter.
Better safe than sorry. But what do you do with them then? As it turns out, the etching process makes the metal particles more harmful environmentally speaking than they were when they were mined from the earth. So pouring them into the ground poisons the area. Once you dissolve them, however, you typically have converted the metal into a water-soluble compound. These are more often than not, toxic.

It might give you a better idea of how long it takes for toner to melt. Stop when you see the toner melt. The copy machine toner you are using may not be good enough for transfer. Try another copy machine and set it for as dark as possible to achieve a thick layer of toner deposited on the paper.

Do you have an electric skillet that can heat the metal from the bottom? If you take the pointy end of the iron and carefully press it on the outer edges without smudging the toner, it may work.
