The fuse blades are aluminum. They will oxidize as they age. Aluminum Oxide (coroundum) has many useful properties, but conductivity isn't one of them. This oxidation increases the resistance of the connection and it heats up, eventually melting the fuse block around the position. New fuses of this type are so cheap that it is more efficient to change, rather than clean them. It's insurance. Do it once a year at least.
