A Hebrew-language consumer tip says burnt pots and blackened cookware can be cleaned with a simple, inexpensive mixture of fresh lemon and charcoal from a barbecue. The article says the method is especially common in rural areas where industrial cleaning products are harder to get, but is now becoming popular worldwide because it is easy and effective.
According to the piece, the only ingredients needed are a fresh piece of charcoal, preferably unused, and a lemon, ideally very sour. The charcoal should be crushed in a bag into a very fine powder and sifted for an even texture. When the powder is mixed with lemon juice, it becomes a powerful cleaner and polisher for aluminum and other metals.
The article explains the science behind the trick in simple terms: the charcoal works as a natural abrasive that removes dirt and black residue without much effort, while the acidity of the lemon helps break down grease that has built up over time. The combination is said to remove even heavy black stains and leave the pot with a bright shine, making it look brand new.
