I did buy a adapter for the vac for doing that job, must be two to three years ago but never used it and would not now know where it is. I also got a brush come squeeze balloon for keyboard never used that neither
I think they think we may be too vigorous or get too close with the vac.They do suck pretty hard. But keeping a sensible distance from components and using an adapter should be fine. Some on this forum even use the brush on the end. Don't think i'm brave enough to try that though.
