Most of what I've read indicates a very basic (high pH) cleaner. Trisodium phosphate has traditionally been the preparation of choice (a 1% solution has a pH of 12), but it is not environmentally friendly.
Detergents which use sodium metasilicates or sodium carbonate may work as well. I suspect that sodium bicarbonate (baking soda) may work in high enough concentrations, if the walls are not too greasy. Use of vinegar is probably contrary to the desired effect, since it will lower the pH and reduce the saponifying effect.
