Woo hoo! I finally washed my razan again and after about 4 times of cleaning it, the smell and taste is almost gone!
Its kinda faint, but I'm sure it'll go away after a few sessions ^_^
but the downer about my hose is that the glue for the mouthpiece grommet came off, so basically my mouthtip is not airtight-no smoke. hehe I need to find some duct tape or something
