Can I dust the Buddha statues offered at home on September 9?

Dust can be removed regularly or at any time. There is no bad day. Be respectful and cautious, take into account the material of the Buddha statue, and don't damage the image.

It's not that buddhas and bodhisattvas have dirt to get rid of, it's that they get rid of ignorance and troubles. Because of ignorance, there is dirt. Besides greed and ignorance, you should beware of wisdom. Except impermanence. Wisdom comes from ignorance.

Wish you worship Buddha and Bodhisattva.
