250–300 ml

A fresh batch every few weeks — a quarter-bar of natural soap, hot water, a teaspoon of glycerin. Gentler on hands than supermarket pump soap, and a single 100 g bar refills the bottle four times over.
Fill the bottle 1/4 with the soap mix, top up with water. The foamer does the rest.
No preservatives — make small batches, use within 3–4 weeks. Smells off? Bin it and start fresh.
