"And my hands are much better after switching from pump soap to your bar soap for my frequent hand washing—no more dry knuckles!"

Mia Barnard from our Facebook page


Classic Soap

Old-Fashioned Lye Soap is great for bathing, shampooing, and washing clothes. Its only scent is the pure, clean soap smell, aka unscented. The age-old soap-making process we use creates a bar that is moisturizing, lathers well and is long-lasting. 

Our Plain Soap Base

We don't want to brag, but this is probably a finer soap than Grandma used to make. We start with fresh food-grade oils in our bars—olive oil, soy oil, and palm kernel oils. Lye is what converts the fats to soap, but not any of the caustic lye is left after saponification. In the process, glycerin is formed. Considered a humectant, glycerin draws moisture from the air to soften your skin.

"I just wanted to say 'thanks' for your amazing soap. I love handmade soap but don't have the time to make it. It means a lot to me that you take the time to make such awesome soap that is also good for people and the planet. I wish more people knew why they should use soap like yours. I will definitely be a customer for life!"

Erika Thompson, Silverdale, WA

"I still use lye soap to clean clothes. It gets out grease the best. I rub a grease stain with lard, set it a while, then clean with the soap. I don't shave up the soap. That's too much work. I put a few pieces of soap in a mesh bag, like oranges come in, and let them dissolve a few minutes in the washing machine until it dissolves, then take the bag out."

Betty Streck, Jefferson City, MO
