I have an enameled robe hook that was installed on the tiled wall inside our
shower, probably over 15 years ago. It looks like it was never designed for
damp/moist applications since the hook fell off the square mounting plate and
the plate is so corroded as to be an unrecognizable rusted mass. I can sort of
make out where one mounting screw is, but that is about it. I've taken a wire
brush to it to try, but that has not yielded anything new in terms of
identifying how it is mounted or how I could remove it. It does look like it
was screwed on top of the tile, which means that any mounting holes were
drilled through the tile and into the wall. I sprayed PB Blaster on the one
screw head I can sort of make out, but there is really no head left that I
could even use a screwdriver on if it works. Thinking about using some kind of
cutoff disc to just slice it off if I can. The plate is about 2" square.

Any thoughts or ideas on how I can get this corroded mess removed with minimal
damage? Am I just going to have to remove the surrounding tiles and then
replace them

TIA!

Is it possible the screws actually came from the back side holding the hook to the mounting plate and that the mount was cemented to the tile?
