Common Questions
Is homemade laundry detergent safe for HE washers?
It depends on your machine and your water. This is a soap-based recipe, not a commercial HE detergent, so it can behave differently (more suds than expected, and more potential for residue in hard water or cold-only washing). Many people use recipes like this in HE washers successfully by using a small amount, making sure it dissolves well, and keeping up with washer cleaning. That said, always check your washer manual and if your manufacturer specifically requires HE detergent, follow that guidance.
If you want the simplest HE routine, use the liquid version for easy dispensing, and consider adding a true water softener if you have hard water.
Will this work in cold water?
It can, but cold water is where soap-based laundry mixes are most likely to disappoint. Soap dissolves and rinses best in warm or hot water, and in hard water it can create more residue (think soap scum, but on laundry). If you wash cold most of the time, you will usually do better with the liquid version plus a water softener, or dissolve your powder dose in a cup of hot water before adding.
Do I have to use borax?
No. Borax mainly acts as a laundry booster by raising alkalinity and helping with water performance. If you skip it, you can still make a solid mix with washing soda and soap. For odors and whites, consider using oxygen bleach (sodium percarbonate) as needed, and follow the product label for dosing.
Will it cause buildup?
It can, especially with hard water, too much product, or cold-only washing. Soap plus minerals can leave residue on fabric and inside the machine over time. The fixes are straightforward: use less, add a true water softener (like Calgon) when needed, run a monthly washer cleaning cycle, and if buildup keeps happening, rotate in a commercial detergent occasionally. Clean clothes are the goal, not detergent loyalty.
Can I add essential oils for scent?
You can, but keep it light. Add 10 to 20 drops per batch of powder, whisk well, and let it sit uncovered for 12 to 24 hours before sealing so it distributes. Avoid adding large amounts of essential oils to the liquid version because they can separate and may spot some fabrics.
What if my clothes still smell weird?
Try one or two of these: wash towels and athletic wear warm once in a while, do not overload the washer, add oxygen bleach (follow package directions), and run a monthly washer-clean cycle. You can also use white vinegar in the fabric softener compartment occasionally, but do not mix it directly with washing soda, and do not use vinegar constantly if your washer manufacturer warns against it (some caution about long-term exposure on rubber seals).
