I have a couple of those

They have white concrete on them, some solidly stuck. How can I remove
it safely to restore the good looks. Thanks

Others have suggested acid, but thats probably not concrete that set in
place. Thats a concrete wet saw, so the white stuff is just dust from old
concrete that dried on. I bet warm soapy water and a nylon brush will take
that right off. A little vinegar couldn't hurt.
