Help! I Get Clumps of Crystals in My Homemade Laundry Detergent

Several times over the past years, I have wished with all my heart I could call Mr. Migaki, my favorite teacher of all time who sparked curiosity and the love of science in my fifth-grade self.

I needed to ask him about minerals and crystals and why borax and washing soda — both of them ingredients in our homemade laundry liquid and powder detergents — can be powdery soft one day and hard as a rock the next.

I was reminded once again of this curiosity when I received this message from EC reader Pat.

Dear Mary: Your Everyday Cheapskate daily newsletter (everydaycheapskate.com/signup) is one of the few emails I receive that I open and read every day, without fail. Both your product recommendations and your recipes are wonderful.

I also use your homemade liquid laundry detergent recipe, and it works well to clean our clothes, but I have a question about it. The last batch I made went into two clean gallon containers, and as I was pouring the last out of the first container, I got a lot of white crystallized lumps at the bottom. So I strained the contents of the second container into another jug and got a lot of the same white crystalized lumps from it. So:

1. Did I do something wrong? The previous several batches were fine and lump-free, and I followed the same recipe with the same ingredients. Maybe other readers have reported the same phenomenon?

2. Do you know what these lumps are?

3. Is the strained liquid going to be an effective cleaning agent? I don’t want to waste a couple washer loads of water with useless detergent if I don’t have to. Your thoughts would be greatly appreciated! — Pat

Dear Pat: First, thanks for being an EC fan. That means the world to me, and I hope you’ll consider sharing EC with your friends and family, so they get it in their inbox every morning, too!

OK, let’s talk about this clumping, or as you call it “crystallized lumps.” This happens for me, and I’ve heard from lots of readers who have experienced the same thing. I notice this happening not right away but maybe a couple of weeks after I make up a new batch of detergent.

I’ve been conducting my own research on this and am satisfied (not alarmed) by what I have learned. These crystals are completely harmless, if only slightly annoying. I shake the container in an attempt to break them up, but even if some remain at the end, I use them as if they were still liquified.

One of the properties of both borax and super washing soda, which are naturally occurring minerals mined from various places around the globe, is that both clump easily when exposed to humidity. The clumping or hardening action is hastened with moisture and heat.

Our original recipe for how to make liquid laundry detergent instructed you to mix the borax and washing soda with hot tap water to dissolve them before proceeding with the other ingredients. That’s the way I have always done it but have been experimenting with changing that to regular cold tap water.

While this has not stopped the crystallization completely, I believe I see less of it — and significant enough that I have amended the recipes to mix with cold water and shake well.

Humidity. With that said, keep in mind that I live in a very dry climate with very little humidity. Depending on the climate conditions where you live, your mileage may vary. And of course, this can change from day to day.

Here’s what you need to know. Whether presenting itself as a lovely clear liquid, soft powder (yes, I do have a powdered laundry detergent option) or a mound of rock-hard crystals, the cleaning properties of borax and super washing soda are not affected. If you end up with a giant crystalized rock-thing in the bottom of your laundry detergent, whack it with the end of a wooden spoon or some other implement to break it up, then use it up as if it were completely liquified — crystals and all. Your laundry will still come out clean and lovely.

Keep it small. If you are still bothered by these crystals, consider making smaller batches of homemade laundry detergent that you will up more quickly.

To keep the box of borax and or washing soda powdery once you’ve opened it, don’t leave it in the box. Instead, store it in a plastic container with a tight-fitting lid or a sealed Mason jar. Or vacuum seal it if you own a FoodSaver or other vacuum sealing machine.
