How to Make Sea Salt Soap

homemade soapI love salt soap. It’s a nice alternative to baking soda when it comes to abrasive cleaners, but still not too harsh. Soap is a unique fat in how well it cleans, with its molecules containing one hydrophilic and one hydrophobic end. This means that one end of the soap molecule loves water, while the other “fears” it-or is attracted to oil. When soap cleans something, one end of its own molecule will attach to the water molecule (which normally just rolls off of the oil) and one end will attach to the oil. When you rinse away the water, the oil goes with it. The same thing goes for dirt, which is either coated in oil or attached to something with oil. It also disrupts surface tension, which makes water “wetter” by disrupting its ability to stay in a spherical drop. The salt mixed in gives it that scrub power to really get things clean.

This is a great recipe to make super fast sea salt soap. It’s great to have around the kitchen and so easy to make.

I can use this for just about any job that requires some good de-gunking skills, but know that it may not work quite as well if you have hard water. Hard water, which is what ultimately results in bathtub rings and soap scum, disables the molecules in soap so they cannot properly do their job.

You will need…
-4 tablespoons of Himalayan pink salt, or coarse sea salt
-8 tablespoons of liquid castile soap
-A glass jar with a tightly fitting lid

Thoroughly stir together the liquid castile soap and your choice of salt. Place in a glass jar with a tightly fitting lid and store out of direct sunlight.

To use, slightly dampen the surface that needs cleaning and sprinkle over the rough side of a sponge. Scrub away!

This mix will eventually harden-this is the ultimate goal! Use a small hard chunk to scrub at greasy pots and pans. If you are impatient for it to harden, pop in the refrigerator for several hours and then break into chunks to use.
