Gorgomyte works great on all fretboards including Maple. I use a clean spot of the Gorgomyte cloth for every 2-3 frets. First I do only the board itself for 2 or 3 frets then do the frets. That way the black impurities from the frets aren't spread onto the board much and it will be much easier to clean it all off with your clean rag. Always keep switching to a clean part of your towel when wiping off otherwise it will take even more effort to rub it off. The finished product is awesome and normal frets feel like stainless frets with hardly any effort.
