Help cleaning dremel bits out of PC.

One other thing on a more serious note

Never use compressed air to remove metal shards / filings from a workpiece - you can use a vacuum cleaner but compressed air will convert the metal into high speed projectiles which have an affinity for the human eyeball - not a good thing

I was swapping motherboards and saw my HDD has a screw in the bay that won't budge, what better time to it then now. Anyway the only way I could unscrew the ******* was using a dremel to cut it and use a flathead screwdriver to take it out, problem is I am very worried about the sparks/metal pieces that may have gotten into my pc case. Right now my case is completely empty and just has the case fans and wires.
How can I clean this safely and thoroughly? I really don't want to mess up my pc when I put it back together. Magnet? Vacuum? Compressed air? Thanks so much

If it were mine I'd probably use several methods. What one misses another would get, in order: blowing, sticky take (masking/printers tape, easier to get into corner than duct tape); wet wiping. Note sure about magnets, unless the case is aluminum.

While it certainly won't hurt to clean the particles out, I wouldn't worry about it that much either. If you had left the motherboard in and it got coated that would be much more concerning.

OK thanks for the replies. So is it okay to use a vacuum inside the case?

Much better than compressed air as long as you have a good nozzle that can get into tight crevices. Rock the nozzle back and forth to get the metal shaving loose. Since they're sharp they tend to stick on everything.

With all the talk about ducks we don't want the OP's issue to fall between the quacks.
