The IUPAC name for table sugar is half a page long. Of course, people argue
about the safety of sugar. Arsenic is technically called arsenic. Draw your

EDTA is pretty OK environmentally, and the grams you'd add to the kilotons
already dumped daily wouldn't matter anyway. It's also been used in common
foods for many years.

-But not quickly except with aluminum. What it will do is remove a thin
passivating layer of oxides, dirt, soap scum and scale to allow fresh
corrosion, as someone else here reported happening in a cleaned kettle.
