This is pretty disgusting and can't be helping efficiency.

I have flat "refrigerator cleaner" but it won't fit under, and snags when I try to go over.
The instructions say it doesn't need to be routinely cleaned, but if particularly dirty, it can be cleaned with a brush on a vacuum. I tried that and the vacuum would have to be a whole lot more powerful to do anything at all. I tried a brush for a shotgun and that kinda works, but I am concerned about what I am going to damage in the process.
Any suggestions? (I mean, other than blowing it out with a compressor. That would work, but I don't think my wife would be happy with the results.)
