Soap scum

[Yeni]

Hey,
Please I make cold pressed soap and I want to sell them but I noticed I always have soap scums in the bathtub. And I doubt if customers will be too happy with that, can I get suggestions on what to do or what can I do to prevent it?

thank you

Hard water can contribute to soap scum buildup because it contains mineral salts. And then soap scum forms when the wet soap interacts with the minerals in your tap water. They combine to form a film or scum that sticks to surfaces.

There are a couple of things you can do. First, use reverse osmosis or distilled water to make your soap. You can also use citric acid as a chelator (adding more lye to counteract the acidity of the citric acid- the calculator does that for you) and that helps a lot.
