Headslap. you ROCK. Thanks.

Get one of those air-blower cans (like you use for cleaning dust from computer keyboards-- you can find them at any office store) to knock it loose and out of the corner, then wipe up with a wet rag.

It's in a spot where I couldn't possibly vacuum..and seems to be stuck in there so a rag isn't helping me much. even my hand it too big for this one corner (think wedged in behind a door in a tight bathroom).

Did you already try vacuuming with the wedge tool? And wiping with a wet rag? I can't believe dust would require a blade, but I have used one for scraping stuff like old paint splatters off the floor.

I'm on a cleaning kick and we have some really tight, extremely hard to reach corners in our house that are filled with dried dust deposits (or whatever). Anyone have a trick for getting rid of these? I halfway considered a straight blade but was afraid I would cut myself!

TIA
