I have wiped a black grease off rack slides, which cuggests it's either 
dirty grease, graphite grease, or moly grease (molybdenum disulphide grease).

I would keep graphite grease away from electrical stuff for obvious 
reasons. But a smear of molu grease, or just plain high melting point 
bearing grease, will do no harm at all IMHO
