Step 1: Pour the vinegar into a bowl. Submerge the rag so that it’s completely soaked with vinegar.
Step 2: Wrap the rag around the base of your faucet (or anywhere you have hard water stains.) Let sit for an hour.
Step 3: Remove the rag and use your old sponge to scrub off any buildup that appears to be coming off.
Step 4: Repeat on the same area if need be, or move the rag onto a different part of the faucet to soak for an hour.
Make sure to keep the rag soaked with vinegar to begin; if you have to pour more vinegar onto the rag when it’s already set on the faucet, that’s okay. The more the merrier in this situation.
Why is vinegar so great for busting up hard water stains? Here’s a quick science lesson for you!
Vinegar contains acetic acid, which is a stronger acid than carbonic acid, found in the hard water stains. In principle, a stronger acid will displace a weaker acid from a salt. Therefore, acetic acid reacts with calcium carbonate to form calcium acetate and the carbonic acid, both of which are soluble in water, and get washed away.
