This is so funny. Same thing happened to us and we used everything, even just about every one of the previous suggestions, to no avail. Until we were told about Starbrite Instant Hull Cleaner. Put it in a spray bottle, spray the area a few squirts and watch it disappear. Rinse with water. Sold at most marine supplies. I got mine on Amazon.
