I have a solder build-up on one of the electrical contacts that holds fuse for my A/C compressor. Does anyone have a suggestion on how to clean up build-up? My compressor is not kicking in properly , and when I checked the fuse I noticed the build-up on the contact. I'm assuming the solder came from a blowm fuse, but am not sure. The fuse seems to be ok, because when I removed the fuse and re-installed it the compressor kicked on when I started A/C, but cycled off fairly quickly.
