haha! quality. Yer clean it out. Remove the lockring with a hammer and a nail. take everything off (remember where it came from otherwise you'll be pretty stuffed putting it back together) then take all the parts and clean them off with a rag. the put it all back together, before you put the lockring back on give it a spray with a light lubricant GT85, chain line finish or something like that. Dont use WD40 as it isnt a lubricant.
