I saw this vinegar hack on Instagram and thought I’d give it a try. You basically pour distilled white vinegar into a small ziplock, submerge the affected area and tie it with a rubber band overnight. Then I used a scrub daddy and wiped off excess stuff in the morning and voila, nearly brand new shower head chain woah! I used it on faucets around the house too, beautiful results. Only warning: the vinegar can eat through cheaper steel.
