I have a few pipes that have stems and bowls that are a little dirtier than the norm. I have heard of fellas using Micro Mesh sanding pads with great success, both to scrub up the stem and do light work on the bowl. I checked the local hardware stores around here recently and came up with nothing. I was told to check a lumber yard but the closest one is hours away. I am even having some difficulty finding this stuff online. Does anyone know where the &!#% I can find this stuff?
