My 43 year old clear anodized mast
is off the boat and I'm trying to clean it up. It has black horzontal stripes on the upper half from halyards slapping. Am trying to clean this off without destroying the clear anodizing. Have tried mild abrasives, rubbing compound, acetone etc but these black stripes, though less noticable, persist. Don't want to go to green ScotchBrite or sandpaper for fear of destroying the anodizing.
Anyone have any ideas how I might clean the stripes off the mast
without damaging it??
