Both powders boost cleaning power, remove stains, and freshen fabrics naturally. But what exactly are they, and how do they differ? In this guide, we’ll break down their uses, benefits, and exactly how you can create an effective laundry detergent using these eco-friendly elements.What is Borax? Borax (sodium borate) is a naturally occurring mineral salt. It’s renowned for its whitening, disinfecting, and deodorizing properties. In laundry, borax raises water pH, softening hard water and allowing laundry soap to work more efficiently. While borax is generally safe, always handle with care as it could cause mild skin irritation if not rinsed thoroughly.What is Washing Soda? Washing soda (sodium carbonate) is a high-alkaline powder that’s superb at lifting grease, breaking down stains, and softening water minerals. Unlike baking soda, washing soda’s alkali strength makes it tough on dirt—ideal for dirty work clothes or heavily soiled sheets.How to Make Borax and Washing Soda Laundry Detergent You’ll need:1 cup borax1 cup washing soda1 bar of soap, grated (such as castile or Fels-Naptha)Mix the borax and washing soda, then blend with grated soap. Store the powder in an airtight jar. For average-sized loads, use 2-3 tablespoons per wash. This blend is budget-friendly, works in both standard and HE (high efficiency) machines, and leaves laundry fresh while being gentle on sensitive skin.Best Practices & Considerations - Always measure carefully: excessive detergent can leave residue. - Don’t use on delicate fabrics like silk or certain wools, as both borax and washing soda are too alkaline for such materials. - Test on a small area if you have skin sensitivities.As a designer, I always think about the full process—storage matters too! Consider using labeled glass jars or chic ceramic canisters for your homemade detergent. Not only does it keep your laundry area neat, but a well-organized space can make daily chores much more pleasant. For those looking to elevate laundry room function and aesthetics, you may want to explore a home designer tool that can help you visualize and optimize your laundry space seamlessly.Tips 1:Keep your borax and washing soda sealed in airtight containers in a dry spot to prevent clumping and preserve potency.
