Thanks for this description. Very helpful.
Your use of "tasteless" is of a concern as anti-freeze, even in small quantities can cause severe renal (kidney) problems.
I would suggest warning against any oral exposure to it and as a side note, pets seem to like anti-freeze. I lost a pet this way. Never leave out where any animals could taste it, even for a minute or two.
