Mainly looking for feedback from those that have used this product on roasted maple boards. I've heard "don't use on maple" yet "safe for use on roasted maple". Now I need to hear from someone that's actually used it on a roasted maple board and can confirm that it's safe to use. I'm obviously wanting to polish the frets but no matter whether I tape off the wood or not, some of the cleaner is bound to make it's way onto the wood at some point. I do understand that anything that anyone does is at their own risk so please don't hesitate to simply relay your own personal experience with this stuff on roasted maple. At least then I can decide if I want to risk it. Thanks very very much.
