Alum Brown is a natural mineral salt traditionally used in leather tanning and dyeing to set colours and improve fabric durability. In traditional wellness practices, it is valued for its astringent properties and is used in water purification and as a natural deodorant. Many households use it as a gentle cleaning agent for cookware and utensils. It also serves as a mordant in natural fabric dyeing, helping plant-based dyes adhere more effectively to fibres. Store in a cool, dry place away from moisture.
