As they say, when life throws lemons, make lemonade...In this case use to clean scales off your taps(lol!!!). It's easy, cheap to use and with little or no residual effect just in case you are unaware. In addition to what we see in video, we must get a hard texture kitchen towel- one that doesn't soften when wet. Then soak in the squeezed out liquid from lemon. Wrap round tap with scales; Leave for about an hour and a half. Afterwards, wipe out with a slightly dampened kitchen tissue/towel. Voila...You get your desired clean result all with your purchased lemons and kitchen tissue rolls.
