When I got into raw denim washing my jeans in the ocean was something I’ve always wanted to try. It was popularised by a French clothing brand and involves wading in seawater with the jeans on then rubbing the jeans with sand. They say the salt water acts as a kind of natural bleach giving denim a subtle fade while sand “beats up” the denim softening it and giving it more character. Raw denim enthusiasts discourage washing jeans in sea water because it can leave a bad smell. However, the smell can be removed by washing the jeans in fresh water and detergent.
