[R-390] Some progress

Sun, 05 Jan 2003 15:54:56 -0500

Hi,

In addition to reacting with oxygen aluminum is very reactive with chlorine.
Since there's salt (sodium chloride) all over the place this can be a
problem. The oxide layer on aluminum will only go just so deep in a
reasonable period of time. As far as I can tell there is no limit to how far
the chloride layer will go.

I have always wondered about cleaners with chlorine in them and aluminum
chassis radios ....

    Take Care!
