Soap is a particularly useful type of bar used for personal cleaning, which increases happiness ("recently took a soapy bath") and lowers the chances of an infection in case of injury, and for cleaning wounds in hospitals, preventing infections from developing. It is thus a vital commodity in dwarven health care, and one not traded in caravans: you're going to have to make soap yourself.

Soap is stored in Bar/Block stockpiles with the "soap" option enabled.

Unlike most other items, bars of soap have a "durability" level which allows jobs to partially consume them – each bar starts with 150 units, and cleaning jobs consume varying quantities of soap before ultimately using it up.

Manufacture

Soap is made of two components, lye plus either tallow from butchering or oil from oil producing plants, and requires a dedicated workshop, the soap maker's workshop. Manufacturing these ingredients from scratch results in a somewhat complicated production process:

• for Lye: Cut down a tree to produce wood logs; turn one log into ash at a wood furnace, then turn that ash into lye at an ashery.
• Tallow or Oil: You have 2 options, and either works the same; you can either...
  • a) for Tallow: Kill an animal, either domestic animal or from hunting, and butcher it at a butcher's shop. Then, render the fat from the butchering into tallow at a kitchen.

  ...OR...

  • b) for Oil: Collect some oil producing plants, either via either gathering or growing crops, respectively, and then process them for their seeds* at a farmer's workshop; these are then pressed at a screw press, producing oil.

    (* Rock nuts are "seeds" from quarry bushes, just with a different, specific name. Olives can be pressed for oil; this works as well.)

• Combine one unit of lye plus one unit of either tallow or oil at a soap maker's workshop, creating a single bar of finished soap.

  (Note: There are a number of by-products produced in either path for tallow or oil; these can be useful to a fortress, but are not relevant to soap making.)

After it's produced, a bar of soap is given a name based on the animal or plant it was derived from; thus you can have a bar of "rattlesnake tallow soap" or "olive oil soap", etc.; this has no effective difference in game play.

Work Orders

Setting up work orders for soap can be tricky, as two of the recommended conditions are wrong:

• The recommended condition for lye is "lye-containing items", but this is incorrect, as a barrel containing 10 items of lye will only count as a single lye-containing item. Instead, for "Type" select "Liquid" and for "Mat" select "Lye", resulting in a condition on simply "lye".
• The recommended condition for the output is simply "bars", which is rather unhelpful. To make a condition for just soap bars, for "Type" select "Bars", and then go into "Adj" and check "Soap items". While many soap materials are listed under "Mat", make sure none of these are selected, as these will check only for that specific kind of soap.

Hygiene

Dwarves do not require soap to clean contaminants such as mud and blood from themselves – if necessary, they will use murky pools, artificial pools of water, brooks, or a well. However, using soap will often generate the happy thought "recently took a soapy bath". It is possible to construct bath-houses (rooms containing pools of water, a soap stockpile, and perhaps a few nice statues) so dwarves living deep underground need not venture to dangerous cave pools or surface brooks to clean off a little mud or some bloodstains. For cleaning wounds and preventing infection after surgery, however, hospitals should be kept stocked with a small amount of soap. Soap will get used up as dwarves wash themselves, and dirtier dwarves consume soap more quickly.

Dwarves have an internal "dirtiness" level, which slowly builds up over time, gets lowered when they have a bath, and lowered further when they have a soapy bath. This "dirtiness" value is connected to the chance of getting an infection if the dwarf is injured, making soap useful as a preventative as well as treatment.
