It should be galvanized. Grinding and sanding will make it rust. If it is
rusting buy a new one. About $10-15 for generic danforth.

Any ideas on cleaning an anchor?
My spare anchor, a small Danforth type, has never been used but is
corroded. Probably from getting wet at the wash rack, I'm a trailer
boater. I tried using my wife's Black & Decker Mouse with an abrasive pad
but it was pretty ineffective. I'm thinking of buying a 4 1/2" angle
grinder - I could probably find other uses for it around the garage.
