Don't. has that person ever dealt with ceramic heads?
I'll go along with that.
Clean it with 91% ISOPROPANAL (alcohol). inspect first during and after.
One minor correction (probably a typo). The stuff you want is
isopropanol. Propanal does exit, it's an aldehyde, something like
C2H5COH. I can't see how an iso-version of that can exist, though - the
nearest you'd get is CH3-CO-CH3, propanone (the new name for acetone).
But keep that away from disk heads...
Most heads are ceramic and oxidized is not
likely.
I suspect 'oxidized' == 'covered with iron oxide from the disk platter'
here.
