While those bleach gel pens they sell in the laundry aisle at the store do have a certain appeal in term of convenience, I’ve never been able to justify buying one. I just couldn’t justify the cost, especially for something I would only use occasionally!
So you can imagine how excited I was when I discovered that not only is it possible to make your own bleach gel pen at home, but that it costs literally pennies to make! That’s all the justification I needed, and it was so much easier than I could have imagined too!
Today I’ll be showing you how it’s done so that you can make your own bleach gel pen at home. I’ll also share a few practical and fun ways to put your homemade bleach pen to good use! :-)
How To Make A DIY Bleach Gel Pen

You’ll need:
- 1 cup water
- 2-4 Tbsp cornstarch
- 1/3 cup liquid bleach
- Small saucepan
- Whisk
- Glass measuring cup
- Squeeze bottle

Directions:
Add the water and about 3 tablespoons of cornstarch to the saucepan. (Feel free to use slightly more if you want a thicker gel, or slightly less if you want it to be on the thin/watery side.) Whisk the mixture until the cornstarch has dissolved completely.

Place the saucepan over medium heat, whisking continuously, until the mixture comes to a boil. Make sure to keep whisking as it heats, or the mixture will quickly turn into a gloopy mess!

Remove the pan from heat and pour the thickened gel mixture into a heat-safe glass measuring cup to cool completely. Once cooled, add the bleach, stir well, then pour the finished bleach gel into a squeeze bottle.

Just cover the stained area with bleach gel, let it sit for a couple of hours, then wash as usual to remove the stains.

While bleach isn’t my first choice as a grout cleaner, it can really come in handy for tackling stubborn grout stains and areas of discoloration. Learn more about how to clean grout here.

And finally, you can use your bleach gel pen to create custom designs on colored fabrics. The applications for this are virtually limitless, as you can customize everything from clothing to throw pillow covers and beyond!
Just draw your chosen design onto the fabric you want to customize, then let the bleach gel sit and dry for a few hours. After waiting, machine wash the item in cold water, and you’re done!
