In case u didn’t know u can easily remove built up calcium hard water stains from kitchen faucets, toilet bugs, shower heads, tiles or basically any surface area that has hard water built up on it. It looks even nastier and stands out more if the surface area is shiny or chrome finished. What you need is one key ingredient which is regular household white vinegar. In most cases where the surface area is unapproachable all u do is I get a rag soak it with vinegar and wrap on and/or around the object you want cleaned. After leaving it on for about an hour just take it off and scrub the surface with a brush or sponge. Depending on the hardness of the buildup u might want to repeat the process.
