ELI5: How do museums keep dust off their artifacts?

Wouldn't feather dusters or blowing them damage them over time?

It depends on the artifact.

The truly valuable or delicate are kept in special cases - climate controlled to ensure perfect humidity, temperature and lighting, and creating a clean and sterile environment.

A lot of things are just kept behind glass - they may accumulate a little dust over time, but since the cases are closed it takes a long time to accumulate and only infrequent cleaning is actually needed.

Other things we don't really worry about - a duster or other suitable cleaning implements isn't realistically going to cause much harm to most everyday objects, so they just clean as necessary.
