Other variants of the product have quaterinary ammonium chlorides or didecyldimonium chloride in them. The aerosols use isobutane as a propellant, another "evil" chemical that's used in the much-reviled "canned goo."
I just remember during my Hazmat training, any chemical containing Chloride as being corrosive to metal.
This more or less what I meant. As combination my not be bleach by name will be corrosive to metal, always.
Edit: to be more specific, regular bleach is sodium hypochlorite. Just seeing chloride doesn't automatically mean bleach. After all, I regularly add sodium chloride to my food and it hasn't killed me yet.
