yo you lookin to scrape it for rez or wht, either way, if you lookin to clean it, put it in hot water, submere the whole thing and it will be clean as a whistle, like, no rez at all, if you lookin for a brick of rez do the same in the sink and use a coffee filter to pick up the rez from the water and squeeze it into a brick, let it dry and smoke...sorry if this post didnt make sense im drunk as a motherfucker
