Let’s talk about bleach pens. Aren’t they one of the handiest home cleaning helpers? I mean, want your grout spick and span? Whip out the bleach pen. Spot clean a white area on a shirt? Bleach pen. Add some designs to your plain jane t-shirts? Hellooooo bleach pen. And what’s even better than a bleach pen? A homemade bleach pen. (And also, how many times can I say the word bleach pen in one paragraph?) Bam.
The best part is, making your own is super simple and only requires 3 ingredients. Seriously, this is as easy as its gets.
Ingredients for Homemade Bleach Pen
1 cup cold water
5 tablespoons cornstarch
5 tablespoons regular bleach
Directions for Making Homemade Bleach Pen
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.
You can see what the gel should look like at this point below.
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.
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.
Below, you can see how I used it to take out a stubborn stain in my favorite white pants. Seriously, before this I had tried adding bleach to the wash cycle, but it still didn’t take the stain out. Whipped out this gel pen, and whalah! All things white again.
I also wanted to show you the consistency of the gel and the bleach power this homemade bleach pen has.
Pretty amazing, right?

What are your favorite ways to use bleach pens? Have you tried a homemade version? I’d love to hear about it!
I give it fiive starts because every time I get involved with bleach, I make a huge mess. This should help
hey what are the nutrition facts for this recipe?
I’m curious as to whether or not this recipe/pen would be suitable to set bleach type designs. Your sample showing consistency is hopeful, but I’m wondering if you have any input on the matter.
Thank you, Cathy
I’m sure it could work for that, yes!
How long did it take to bleach that line on the dark pink shirt? My son is making a bleach design on a shirt, and it doesn’t seem to be working. . . Any hints?
Turned out too thick. Needs way more water. Should have described or shown consistency of how it should look before you put it in a tube. Mine was so thick it wouldn’t squeeze out so I had to dork with taking it out and adding more water. Not fun to play with stinky bleach! Wish chlorox would just make their pre made bleach pens again. This is to much of a time consuming pita.
Hi so I made this because I use about 2-4 bleach pens a month. I wear a white coat at my job that needs to be white all the time. Is there anything I can do to keep it from breaking down and becoming watery after 24 hours? Either way I will still use this recipe because it’s cheaper and better on the environment and gets crazy food and oil stains off my shirt.
Hmmm… I’m wondering if maybe a small shaker bottle would work or if you keep the mix in a container you can quickly and easily stir?
Hello thank you for you reply. I found that making smaller batches and shaking together before each use helps the effectiveness of the bleach on stains. Although it does thin out after 24 hours. I make a half batch about once a week so it’s worth the ten minutes it takes because this gets out pen, protein, oily food residue, wine stains, pretty much anything I encounter at work.
So so happy you let me know that!!! Much appreciation!!!
