Things You'll Need
Instructions
Clear heavy debris from the track. Leaves, loose dirt and other debris can be easily swept away with a soft broom. Take care not to pull the track from its place when sweeping.
Wipe down the track with a cloth soaked in alcohol. An innocent bug walking along the track becomes a slimy mess when run over by a screeching locomotive. Snails and slugs crawling along the track will leave a slimy trail in their wake. Tree sap leaves its sticky mark anywhere it lands. Alcohol is a solvent which can quickly dissolve and remove these messes.
Attach a dry wall sanding screen to a sanding block. Depending on your preference, you can use a handheld block or a pole block. A pole block allows you to stand while sanding, which is good if a light sanding is needed. The handheld block is a better choice when detail work is needed.
Sand the top layer of the track with a gentle motion. Several strokes are better than trying to get the job done in one shot, as you may push too hard and ruin your layout.
