RLN-27 DERUSTING CHEMICAL When using RLN-27 or any derusting chemical, it's important to follow the manufacturer's instructions carefully. This usually involves applying the chemical to the rusted surface, allowing it to penetrate and dissolve the rust, and then rinsing or wiping away the residue. Protective equipment such as gloves and goggles should be worn to prevent skin contact or eye irritation. After using a derusting chemical like RLN-27, it's recommended to clean and dry the metal surface thoroughly and apply a protective coating or paint to prevent future rusting. Always ensure proper ventilation when working with derusting chemicals, and dispose of any waste material according to local regulations for chemical disposal.
