Does anyone know how to clean Micarta without messing it up? I know this almost sounds like a joke question but I am serious, here is why. For the last three years or so I have EDC'ed a Rukus almost everyday. It has, just like all micarta, picked up oil from my hands over the years. Now it is dark and you can see light areas under the clip, and where the indentation for the clip on the other side is. I have used Carb cleaner, acetone, and even used the parts washer at work, still can't get it clean. Suggestions?
