Maybe the quiet is a good sign. If your paint question was totally wrong, people would jump in to correct it fast. That one thumbs up could mean your info was solid and there was nothing to add. Keith744, your buddy's plumbing post might have been the same. Sometimes no news is good news, and a post that doesn't start a fight just slips by. This place can feel helpful even when it's quiet.

Glad you switched methods before doing real damage. That compressed air trick can actually force dust into the fan bearings and kill them for good. The brush and vac combo is solid, but for stuff that's basically glued on, I'll sometimes use a soft toothbrush to gently break it up first. Just go slow and keep the vacuum nozzle right there to catch the clumps as they come loose.

Totally changed my whole training plan after a similar report. I used to spend an hour on sensor specs and now I do a whole comedy routine on "how to not set off your own alarm." My best bit is acting out a cat's midnight zoomies setting off every motion detector in the house. The stats don't lie, we're often our own worst enemy!
