Since it's hot in Florida, and I do some perspiring, the guitar is getting dirty. The combination of my skin oil and the dust in the air is especially showing where my right arm rests on the body.
What do I clean it with? Pardon the ignorance, but guitar is my 7th instrument and I still have a lot to learn.
This is what it looked like when it was new (before It got dirty).

Thanks,
