How do I use Pure-Castile Magic Soap for laundry?Updated a day ago

Our Pure-Castile Magic Soap works wonderfully for handwashing and in both regular and high-efficiency (HE) washing machines. However, please note that although our products are not HE-certified, we receive a lot of positive feedback from customers who use our soaps in their HE washers.

To wash your laundry in an HE washing machine, you will only need ¼ cup of Magic Soap (any scent). If you have a regular washing machine, you can double this amount, using ⅓ – ½ cup of soap.

If you use our Magic Soap and have hard water, you may notice some mineral build-up on your clothes. Rest assured that this is completely normal, as the interaction of hard water, and even soft water, with any true soap (not synthetic detergent-based soaps), can leave behind a thin film of minerals that appears as residue or “soap scum.”

But this residue can be easily washed off most items using one of two methods. 

  1. The first would be to wash the affected items with our Magic Soap as usual, and also add ¼-½ cup of baking soda to the load and ¼-½ cup of vinegar to your fabric softener compartment (or rinse cycle). The baking soda brightens, deodorizes, and scrubs during the wash, while the vinegar breaks down any residue and naturally softens your fabric during the rinse cycle. 
  2. The second method is to wash your items with our Sal Suds Biodegradable Cleaner instead of our soap. Sal Suds is a mild detergent, meaning it is gentle enough to wash your clothing, but it does not interact with hard water the way Pure-Castile Soap can. It is also excellent at breaking down and cleaning any residue caused by our Pure-Castile Soaps. For the best cleaning, you can use both methods: wash your items with Sal Suds, then add baking soda and vinegar.

If you have any delicate garments, such as silk or vintage items, or waterproof materials, we recommend doing a spot test first to ensure this product is safe to use. Our products are intended for general use and can be used for many different purposes. However, because they are not specifically formulated for laundry, we have not tested them for all types of fabrics. When washing items by hand, you may add a few drops of soap as needed.
