Betadine Skin Prep 500ml - Betadine antiseptics are among the most effective antiseptics available, inactivating all known types of infecting organisms - bacteria, fungi and even viruses. The brown colour of Betadine antiseptics shows the area that has been treated and also denotes the activity of the product. While it's brown, it's working. In most cases, Betadine antiseptics are non-irritating and non-stinging to the skin. They do not permanently stain the skin or natural fabrics and the treated areas may be bandaged, taped or otherwise covered
