Ready to take control of your laundry routine with a fun, easy DIY project? Summer in Georgia brings the heat, and with it, an endless cycle of laundry.

If you find yourself running the washing machine more than ever, why not mix things up and save some money with your very own homemade liquid laundry detergent?

This homemade liquid laundry detergent recipe is not only economical but also a breeze to make. It uses simple, easily accessible ingredients like Borax, Kirk’s Castile Soap, washing soda, and a few cups of water.

These materials that promise to tackle even the toughest of stains without the harsh chemicals found in store-bought brands.

Ideal for those with sensitive skin or anyone looking to reduce their household’s chemical exposure, this detergent skips the dyes, fragrances, and additives typical of commercial options. And if you’re missing that fresh, just-washed scent, pop in a few drops of your favorite essential oils.

One of the greatest perks of this liquid detergent, aside from its effectiveness and skin-friendliness, is its compatibility with HE (high-efficiency) machines.

Designed to produce low suds, it meets the specific needs of these machines, ensuring a smooth run with every load. Plus, it leaves no residues like some powdery detergents do, so you can say goodbye to undissolved bits on your freshly washed clothes.

While this DIY mix comes with heaps of benefits, here’s a quick heads-up: it’s a good idea to be around the house the first time you use it, just to ensure everything goes smoothly with your particular model of washing machine. Though I’ve yet to hear any mishaps, it’s always best to play it safe!

Optional: microwave a bar of soap in five second increments for a total of 20 seconds. After each five seconds, flip bar of soap onto the other side. This softens the soap so cutting it is easier!

To use your detergent: pour 1/4 cup into your washing machine’s liquid dispenser. Launder as usual.

If the soap gets solid, microwave the jar!

My soap layered out and even solidified a bit after a week, anything I did wrong?


Saturday 3rd of June 2023

@Amy, my mixture gelled once cooled. I used a handheld mixer to liquify it.

@Taylor, I used the Zote flakes and it did the same thing for me. I’ve mixed it up and it’s more of a gel than a liquid but it works well for me. I add it to the drum instead of using the dispenser.

Hmmm I haven't heard of or experienced that yet. Was it kept in a hot or cold place and did you use the exact same ingredients that I did? I'm thinking you could microwave it if it's in a glass jar.

Is the 1/4 cup measurement for he or regular washers?

Will zote soap work for this recipe? I already have a bar at the house and wanted to try this out.


Thursday 28th of July 2022

Hi Elizabeth! Did a little research and yes, supposedly it works! Please for me on the first batch, just do towels or something and make sure it works okay. Don't use nice clothing. Just because you never know :)
