Hey i was wondering if someone could help me

ive got a dunlop crybaby gcb 95 and had it quite a while but i think it needs some more grease/lube

what is the best stuff to use

ive got wd 40
and motor bike chain wax

can i use either of them



WD40 is general consensus from what ive heard, but im not sure, but WD40 doesnt harm anything unless you swallow it :P
