Ok guys, be gentle. Total noob, 1st post. Sorry if it's long.
My daughter wants to learn to surf. Wife and I are completely cool with it. We live a block from the beach. Daughter turned 8 this past winter, digs body boarding, started at 6. Got my first Boogie Board almost 40 years ago. Decided to work her up to a legit board. Wanted to get her a Beater, but didn't want to drop the coin. Salvaged one in decent condition, needed a little TLC. Bought some fins and a leash. Needs to be re-formed, currently nosedives. I'm about to handle that, BUT it looks like the previous owner rubbed a puck on it once, and I'd like to remove it first. What's the best to remove that thin, sticky layer from a slightly textured foamboard? Only thing I can thinks of is hot water and gentle scraping using a steel wool-like pot scrubber.
