A crate can be fitted well and still pick up little scratches at the last minute. Often the culprit is not the tool in your hand; it is the grit, screw shavings or dried glue crumbs already sitting on the bench.
Before final sanding, oiling, staining or packing a finished piece, give the bench one deliberate broom pass. Use a clean bench brush, sweep away from the crate, and lift the piece instead of dragging it through the pile you just made.
Corners deserve a second look. Dust likes to sit inside handle cutouts, under dividers and along the little ledge where a slat meets a rail. A soft brush or folded rag can clear those spots without rounding over an edge that should stay crisp.
Keep the dirty brush separate from the finishing brush. One can live near the saw or drill for shavings; the cleaner one should stay by the assembly or finishing area. If both brushes look the same, wrap tape around the handle of the clean one.
This habit is especially useful on small display crates and gift boxes, where the inside corners are as visible as the outside face. Five seconds of sweeping is faster than chasing a scratch after finish has gone on.
Practical takeaway: before the last sanding pass or finish coat, lift the crate, sweep the bench, brush out the inside corners, and only then set the work back down on a clean surface.
