Sand Between Finish Coats

Sand with the grain

A sanding block works best

It's best to use a sanding block, either a commercial sanding block or a piece of wood just the right size to fit comfortably in your hand. A thin piece of foam around a quarter of an inch thick or a few folds of paper towel between the sandpaper and the sanding block will help get a smooth finish on a slightly uneven surface without sanding the finish too thin on the high spots.

Clean with a damp cloth

If you're wet sanding clean the surface well with a damp cloth. Fold the cloth several times so you can keep refolding to expose a new surface so you can be sure to get all the sanding residue cleaned off before you apply another coat of finish.

Clean with a tack cloth

If you're dry sanding clean the residue with a tack cloth. Even a minute speck of sanding dust left behind will show up like Mt. Rainier in the final finish.
