rejected.content: Chemicals, such as acid, used for mortar breaking down are hydrochloric acid, muriatic acid, or citric acid. Depending on the type of mortar and brick, different strengths and solutions of these acids may be needed. It is important to use caution when dealing with acids as they can be corrosive and damage skin and eyes. Furthermore, one should use protective gear, such as a mask and gloves, to prevent injury. It is best to wear long sleeves, long trousers, and safety glasses as well. Finally, it is essential to wear protective footwear as you will likely be working outdoors.
