well i have been different and just streatched my left lobe to 10mm, looks kind of cool and not big enough to make my head look lop sided

I wash my lobe on a regular basis and alternate what i wear in it depending on my mood or how i feel. However i have noticed a kind of sweet sickly smell on my fingers if i rub my lobe or just generally fiddle with whats in it. Its not an odour that is strong, ie i can only smell it on my fingers after rubbing my ear.
so my question is :- what can i do to eliminate or reduce the smell? i was thinking of surgical wipes or something like that, i am almost sure it is a general everyday sweat and muck problem.
thanks
