im sure some others of you have a similar set up. My layout is in the garage and we live in a wind prone area so lots of dust is normal. I do the usual track cleaning, but about once a year it gets to the point I need to clear everything out, vacuume the surface, clean the track then dust everything well. Also swapping the Ives bridge out for a Dorfan. This is the week thanks to some exquisite weather.
