First heard the term in 1988 to describe an MS64 1855-O half I had purchased with purplish mottled toning. Someone said it looked like it was cloroxed. It later came back AT from NGC. It was an eye opening experience not to mention a 20% hit. Everytime I run into the seller it's hard not to think of that purchase.

I've heard of it, and my understanding is that since it colors the coin using chlorine instead of sulfur, you can't really get the awful color off like you can with some other forms of toning. Dipping doesn't work.
Just like other forms of doctoring, clorox is meant to hide something bad, so when you see a cloroxed coin you know 1) it's ugly from the clorox, and 2) the clorox is hiding something even uglier.
The guys I know who used to tone coins artificially used light bulbs. I guess that won't work so well with the new low heat ones that are mandated by the government.

I heard about 'cloroxing' somewhere a long time ago. I believe this trade dollar was given that 'treatment' to hide an old cleaning; note the purplish hue:
Since acetone and hot water wouldn't remove it, I dipped it, and the color came right off:

now retoning in a paper envelope.
