How to Remove Iodine Stains From the Walls
- 1). Mix 1 qt. water with 1/2 tsp. liquid laundry detergent and 1 tbsp. ammonia. Don't use detergent that contains bleach. Never combine bleach and ammonia. Toxic fumes will result.
- 2). Dip a cloth into the solution, and hold it over the iodine stain. Hold it there at least 10 minutes.
- 3). Remove the cloth, and scrub the iodine stain until it is gone.
- 4). Mix 1 tbsp. sodium thiosulfate with 1 cup water, if the iodine stain is still visible.
- 5). Dip a cloth into the solution, and rub it over the stain until the stain is gone.
