Brass brush to remove old wax
In my reading, I've seen a couple methods to remove the old wax prior to doing a hot wax on your board. Although using a base cleaner seems to be the most common (and what I've been using), the other I've seen is to use a brass brush. Are we talking about a brush with actual brass bristles? I know this is probably pretty self explanatory, but it just doesn't seem like I'd want to use metal on my board. I'd also love to hear any pros and cons for using a base cleaner versus a brass brush.
