To remove wax:
Next time you are at the beach on a hotish day face your top deck up and put a thin layer of beach sand over the wax.
Leave for board for a few minutes until you notice the wax melting. Use the smooth end of a wax saver to scrape the wax off. It comes off really easy. Just remember to throw the sand and wax in a bag for disposal.
You could just scrape it off with the back of a wax comb
Hot water and sun are fine for melting off the bulk of the wax but if you want to glue something to the deck or glass over it then you're going to need to get out some serious solvent the remove all traces of wax.
Acetone works once the bulk of the wax is removed. Lacquer thinners would probably do the job. Petrol's OK (for non smokers) but doesn't seem to get it all off
