Before important shows, I usually do a little maintenance on my Cirrus. Remove the strings and denatured alcohol them, or just put new ones on, wipe the thing down from top to bottom. Lately I've been using a spray cleaner for guitars, but noticed that it is specifically for cleaning the finish on guitars, not unfinished wood. I havent noticed any ill effects from using it, and it seems to evaporate and not leave a noticeable residue. This probably isnt the best cleaner I could be using. I am kind of broke right now and was wondering what other options there using basic household products, if anything. I just want to remove the dirt/skin residue from the wood without damaging it.
