Bulk Natural Castile Laundry Soap Powder


Our laundry soap is a family recipe that has been put to the test for years. From heavy, grimy loads of denim after hay hauling to daily, nasty loads of reusable diapers, this castile laundry soap is the only thing we have used for over a decade and we have no desire to switch to anything else!

  • Put your scented laundry soap powder in an open container to scent your laundry area.
  • Use an organic wool dryer ball with essential oil drops in the dryer to make the scent on your laundry stronger!

15 pounds of castile laundry soap is 240 ounces. Since an average load of laundry needs just an ounce of our laundry soap powder, a 15-pound batch will last you about 240 loads.

> If that’s too much at once, you can order in three-pound bags here.

> We also offer our laundry soap in one pound bag samples (16 oz.) if you’d like to try it out first.

Ingredients: Our laundry soap powder is a combination of washing soda, borax, baking soda, and shavings of our traditional castile olive oil soap (olive oil, lye, water).

– Select Unscented or an Essential Oil to keep the laundry soap all natural. We offer high-quality fragrance oil scents as well, but fragrance oils are not biodegradable or all-natural.

NOTE: The scent on your laundry afterward is not super strong or overwhelming. If you would like a heavier scent load, add a note to your order or use a few drops of oil on an organic wool dryer ball.

Directions for Use:

> Add one tablespoon of powder directly to the top of laundry in the washer for a medium load.

> Use two tablespoons of powder for a heavy load.

> Use up to 1/4 cup for a particularly heavy, nasty, greasy load.

> I have never had to use a fabric softener with this laundry soap. My clothes, towels, and sheets always come out soft and clean. But if you feel that you should use something, use 1/4 cup of white vinegar. A cheap and natural fabric softener!
