>>9629349I use a makeup brush for the figures and a small vacuum for the shelves. It is not that hard. If you have too much shit, invest in display cases or glass doors, which will get less dust and have to be dusted less often. Half my collection is behind glass and the other half is open. I dust the stuff out in the open once a month, the stuff behind glass I dust every three months. If you don't let it build up, it's not hard to remove. It's only hard to remove if you let shit sit out in the open for a year.
I also rotate my displays by putting certain figures into storage and putting other ones out, which helps keep things fresh, prevents things from looking like a clusterfuck, and also helps with the dust problem.
