There is no elegant way to clean surfing wax off your wetsuit. You shouldnt really care if you have some wax on your wetsuit or your boardshorts. If you use your wetsuit you will have wax on it. The only way to get the wax off is to scrape it off. All other ways can harm your wetsuit. Like using chemicals or hot water – this can destroy the neoprene. What else can you do? Don’t wax your board where you sit and use a harder wax that won’t rub off so much.
