The detail behind the facts
Dry first
A soft goat-hair brush or air blower removes most dust without touching the surface.
Studios that publish care notes tend to be the ones whose secondary-market prices hold, and this point is usually the reason why.
Damp method
A barely damp microfiber cloth with distilled water is safe on diecast metal.
Collectors who skip this step usually discover the problem the hard way — a faded shoulder, a pitted alloy base, or a certificate that no longer matches the listing.
Detail work
Cotton swabs reach panel lines and recesses; work top-down so grime does not re-settle.
Most first-time buyers only feel the real constraint after the piece has sat in its box for a season — by then the easy window to decide has already closed.
How collectors apply this
