TSP: Trisodium Phosphate
As I was reading the ingredient list on my box of Cheerios, I saw a very familiar chemical name: trisodium phosphate. I knew this chemical name from somewhere, and then I remembered:

Heavy duty cleaner. Effectively controls lead paint dust.

Most of the back of the TSP heavy duty cleaner box is filled with very detailed instructions, most of which involve the phrase DO NOT.

Including the following:

DO NOT take internally.

I'm sure that there is a very good explanation for this. Something very benign, like the chemical comes in both food grade and industrial grade varieties. But I still find it disconcerting.
