I decided to swap out all my hookah hoses with these because I just love them. I have white, blue and a few black ones. Maintenance is a breeze; just run hot water through them. I haven't had any shisha ghosting of flavors with this method, if you do then I have used a mixture of baking soda and lemon juice, if that still doesn't help then these are affordable so just swap it for a new one. Thanks again Masonshishaware for another exceptional product.
