Your shower head deserves respect. It rains on you every day. Pay it back with a vinegar bath.
Do this today. Walk into your bathroom like a boss. Tie that bag on. Feel the power of chemistry in your hands.
Tomorrow morning, step under a glorious, powerful spray. Feel the warmth. Revel in the lack of crust. You are a calcium conqueror.
Now go. Find that vinegar. Free your nozzles. Your skin thanks you. Your water bill thanks you. And that grumpy shower head will finally smile. Probably.
