How should a detailed 3D-printed house model be dusted?

What’s a safe routine for removing dust from a detailed 3D-printed home model without bending thin walls or knocking off small balconies and other delicate parts? I’m also unsure whether a soft brush or dry air is preferable, since the right approach may depend on the print material and surface finish.

What material and finish does your advice apply to, and are there signs of surface wear or fragility that mean it’s better to ask the fabricator before trying a cleaner or repair?
