Pickling is a common process in jewellery making to clean and brighten precious metals after soldering. The process involves dipping the metal parts in a pickling solution, usually made up of an acid and water, to remove any fire scale or tarnish that may have accumulated during the soldering process. Traditionally, pickling solutions were made with strong acids such as sulphuric acid. However, these strong acids can be dangerous and damage the metal if not used properly. They can also have a negative impact on the environment and the health of the user. For this reason, it is best to use acid-free alternatives for pickling. Durston's acid-free stain solution is environmentally friendly and safe to use. The novel formula also makes it gentle on the metal, yet highly effective in removing burnt scale and tarnish. It leaves no residue on the metal and ensures that your jewellery retains its best appearance.
