2. Best descale product: Coca-Cola
A lot of people are reticent regarding cleaning with Coca-Cola, even if it has been proven that the results are pretty amazing. Why? Because they think it will leave the shower sticky. That’s false! And you will see why. For a deep clean with soda, you only need a plastic bag, a bottle of Coca-Cola and a clean cloth (or a soft toothbrush if possible). Sink the shower head into the bag almost full of liquid and then let it soak for about 15 minutes. After that, clean the remaining liquid from the shower head with a dry cloth and then wash it with cold water. Repeat the process if it’s not clean enough.
