For 8x10 I use the wooden holders made by Folmer-Graflex. The light traps can be disassembled to clean out the dust which lurks there. If the holders get very dirty, the light trap is usually (with newer holders) the one area you cannot access for cleaning.

I also vacuum the inside of the camera regularly.
