just got a Burton Joystick a couple weeks ago and went out to ride it for the first time a couple days ago. it's got a sintered base and it came pre-waxed from the factory so I didn't wax it before I went out. When I got home I noticed there was a little dirt caked onto the entire base of the board. Is there a way I clean off this dirt without taking off the wax as well? if I take a damp paper towel to it, will it take the wax off?
Water on a rag isn't going to do anything and stripping wax off with base cleaners supposedly makes the base just as slow as dirty wax...so it's a no-win situation. If possible, I'd just brass brush, do a hot scrape then a regular hot wax (a lot of work for crappy snow).
Theres a thread about almost this same question. Titled black stuff on board or something like that. But its not in the board its in the wax. Take an iron to the old wax to melt it and wipe it off or scrape it. Then rewax.
