How to Remove Food Coloring From Water
- 1). Put on safety goggles or protective eye gear.
- 2). Add a few drops of bleach at a time into the food coloring and water mixture. You only need to add small amounts of bleach depending on the strength of the food coloring solution. Once you have added bleach to the water, it cannot be used in foods or to drink. Bleach solutions should also not be used to water houseplants or to water pets.
- 3). Use a spoon or a plastic stirrer to fully incorporate the bleach into the food coloring and water solution. The water may still be cloudy or lightly colored.
- 4). Mix in additional bleach a few drops at a time until the water is completely clear. Keep track of how much bleach you added to the solution if you want to recreate the process with additional food coloring.
