Except this soap, also vinegar for surfaces, plates etc was used, soda for various purposes and something else that i don't know the word in english, if it exists, but it used in traditional soap maki...
Vinegar, baking soda, and lemons are my all-time go-to too! Then, tomato with salt for copper (learned this hack from a copper master).
About the soap: I did learn that soap was initially made with ash, then with animal fat, and later with olive oil.
