Why not try compressed air?
Some of us are burdened with brains. You are one of the lucky few.
I go over this with my GF everytime we have ice cream... She doesn't understand how I can eat it so fast, she suffers from brain freeze.... I tell her I'm lucky, you can't freeze what you don't have...
I'm not sure modern brake clean will do the job, might want to grab the carb cleaner..
Car keys get in there and scrape out the crusties. Some work better than others. Old worn out keys are easier on the skin.
Bourbon is my favorite.
