My oven sits in between two countertops with perhaps 1/2 inch of total wiggle room, which means that I have two roughly 1/4 inch gaps that are ~36in deep in which all manner of crumbs and food mess falls on a regular basis. I'd like to clean these areas out to cut down on any food smells and potential insect issues, but I haven't come across any good solutions for doing so.
Anyone have any suggestions for cleaning crumbs (and potentially stuck on food) out of long but narrow gaps?
Edit: Someone asked about what I'd tried so far, so adding that as a note here: My first thought was to secure a Swiffer or other dust-collecting cloth to a meter stick to make the equivalent of a narrow duster, but this was still too thick to fit inside the gap. I haven't found any other long stick-like implements that are long enough to reach in far enough while still being thin enough to meet the gap. I'm in an apartment, so I didn't see how the oven was put in and thus am hesitant to try pulling it out of place. I have, however, removed the oven's bottom storage pan and cleaned underneath it. That's helped, but I suspect there's more waiting in the wings, so to speak
