After using On & Off to clean barnacles off the hull of my skiff, I'll never fail to follow the instructions and read the MSDS.

On & Off contains hydrochloric, phosphoric and oxalic acids and, although I was outside, I was technically in a confined space -- lying on my back with the boat's hull inches over my face. I think I got out of there before doing permanent damage, but breathing that stuff for even a few seconds can really burn your airways.

Edit: Ha, Mr RT! Great minds . . .

Here's the source I was citing for ingredients: http://www.jamestowndistributors.com...ll_cleaner.pdf

Great thread, BTW.
