Just checked my Rust Free label. Phosphoric acid is listed as the active
ingredient. Not so nasty. We use it in the janitorial industry to as an
alternative to hydrochloric acid for removing water deposits from steel,
chrome, tile, masonry etc. If it gets on your skin just rinse it off.
No
need to even hurry.

I stand corrected. I had it confused with another rust removal product.
The other one is nasty! I don't think its sold any more.
