Ingredients

  • 1 cup cold water
  • tbsp cornstarch
  • 5 tbsp regular bleach

Instructions

  • Mix cold water and cornstarch together in a medium sized saucepan. It’s important that the water is cold so that the cornstarch doesn’t cause any lumps in the gel. Over medium high heat, stir the mixture continuously until it is very thick and pasty. Remove from heat and let cool completely.
  • Add the bleach to the gel and blend well. Carefully pour the gel mixture into container of choice. I have a bunch of these clear condiment bottles from Walmart that work great. An empty glue bottle would be even better if you need the nozzle to be a tad smaller.

Notes

When working with bleach, it’s always a good idea to wear gloves to protect hands, and clothing that you're not too worried about in case of any splashing.
Use in the same way you would use a regular gel bleach pen. I made my version with regular strength bleach, so make sure to compensate if you are using an extra strength formula.
