Advice for cleaning wildfire smoke from headset?

So my Quest 3 was in the area of one of the recent fires in Los Angeles. While thankfully my home did not go up in flames, wildfire smoke and some ash did get into the house. That has left residual toxic smoke in a lot of things in the house, including the headset. Any advice for cleaning the smoke out of the fabric parts, especially the facial interface? I can't exactly throw it in the washing machine.
