As @Ronbrink and @Galileo stated. We have a small rechargeable handheld vacuum that we use every couple of days to pick up most of the dirt. After that, a quick wipe down with a cloth sprayed with "Wash and Wax All" keeps things clean. So far, it's working well for us. If anything stubborn remains, we use a little toothbrush or a Q-tip to tackle it, for us this has been rare.
