still rust? how much? wonder if vinegar will do? works great just not as fast or toxic.
So what if it's toxic......... and how ?
Fumes avoid inhaling it, he's not going to drink it. Seems to be the logical and common sense way of avoiding the toxicity. If it were true and it very well maybe, and I say again so what ....?
The suggestion put forth, vinegar calming, insinuating is a better method. You have no clue if it even works.
Suggest you try it, and get back to us, if it fails, you have only wasted your own time.
All these nannies today are the toxic ones. Without facts or experiences, pollute conversations.
