Castile soap has become a household staple for the environmentally conscious among us. Named after the olive oil-based soaps that originated in Castile, Spain, Castile soap can come in liquid or bar form, but it is made only from vegetable oils, meaning zero animal fats.
Like almost all soaps, which are on the more basic or alkaline side of the pH scale, Castile soap shows up at about 8.9 on the pH scale. That puts it in the same ballpark as baking soda or slightly more alkaline than mild dish soap.
How Does Castile Soap Work?
In case you weren’t paying attention in science class during high school, soap molecules have one end that is attracted to water and the other end that avoids it. That means when soap is combined with water, it creates miraculous free-floating charged atoms that attract and capture dirt and other types of non-water-soluble molecules.
That grease-grabbing quality makes Castile soap especially useful on slick oven hoods, greasy pots and pans, and hard-to-clean oily spills. Although commercially made soap like Dr. Bronner markets his Castile soap for 18 uses, we have found many more than that.
Castile soap and water can be used to clean your counters, sinks, bathtubs, floors, or toilets; it can get rid of insects that infest houseplants and can even replace laundry detergent.
Because Castile soap is biodegradable and nontoxic, it’s safe to use on pets and around kids. You can even clean vegetables with it, as long as it’s diluted enough.
