How to Clean and Dry Clothes in Project Zomboid (Build 42.19)

How to Clean and Dry Clothes in Project Zomboid (Build 42.19)

Build 42.19 · Vanilla laundry · Cleaning and drying are separate

Quick answer Wet clothes dry on their own over time, or faster in a powered Clothing Dryer (or Combo unit set to dryer mode). Blood and dirt are a different problem: wash them off by hand at a water source, or with a Washing Machine / combo washer mode that has both water and power. You do not need to wash before drying, and drying never removes stains.

Two problems, two fixes

Problem What it does How to fix it What does not fix it
Wetness High wetness can lead to catching a cold (Has a Cold moodle). Rain, swimming, and washing all raise wetness. Wait for natural drying; use a Clothing Dryer; or set Combo Washer/Dryer to dryer mode. Washing again (hand wash makes clothing fully wet).
Blood / dirt on clothes Dirty or bloodied clothes make ordinary wound infections more likely. This is not Knox/zombie infection. Hand wash at a sink/bath/river/lake, or run a washer (or combo in washer mode) with water and power. Soap speeds hand washing a lot. Putting clothes in a dryer. Drying only lowers wetness.
Do not mix the health effects Wet clothes and bloodied clothes are not the same threat. Drying a blood-soaked shirt does not clean it. Washing a wet shirt makes it fully wet again until it air-dries or you use a dryer.

How to dry clothes

Any wet item can dry without washing first. Use the method that matches your power and time budget.

Method Requirements Notes
Natural drying None (time) Default option. Wetness falls over time based on environment and clothing; keep a spare dry layer if you can.
Clothing Dryer Electricity only Common in houses and laundromats. Open the dryer container, load wet clothes, turn it on. No water connection required.
Combo Washer/Dryer · dryer mode Electricity only Right-click the unit (or use the inventory window controls) and set mode to dryer, then turn it on. Water is not required in dryer mode.

Combo units can switch between washer and dryer modes. Dryer mode needs power; washer mode needs power and water.

Using a dryer step by step

  1. Find a Clothing Dryer or a Combo Washer Dryer (including blue combo units you can pick up and move).
  2. Confirm the machine is powered (grid power or a nearby working generator).
  3. For a combo unit, set mode to dryer before starting if it is currently on washer.
  4. Put wet clothes into the machine’s 20-slot container and turn it on.
  5. Wait until wetness drops, then take the clothes out. Stains and blood remain until you wash.

How to clean clothes

Cleaning removes blood and dirt. After a successful hand wash, clothing is fully wet again, so plan a dry step afterward if you need to stay dry.

Hand wash

  1. Stand at a water source you can use (sink, bath, well, river, lake, rain collector with access, and similar).
  2. Right-click the water source (or use the wash options) and wash one item or All Clothing.
  3. Keep Soap (or cleaning liquid that counts as soap) in inventory. Without soap, washing takes about 5× longer.
  4. Stay somewhere secure while the action runs—washing is not instant.

Water use scales with how bloody and dirty the item is. Soap is consumed when clearing blood stains; dirt can still be cleaned, but soap makes the job practical in combat-heavy runs.

Washing Machine

  1. Load clothes into the Washing Machine container (20 slots).
  2. Confirm power and a positive water supply on the machine. Turn On only appears when both are available.
  3. Start the machine and wait. This cleans; it is not a substitute for a dryer if you only care about wetness.

Combo Washer/Dryer · washer mode

  1. Set the combo unit to washer mode.
  2. Ensure power and water. Washer mode is blocked when water is empty (the machine will say it needs a water supply).
  3. Load clothes, turn on, then switch to dryer mode later if you want machine drying in the same appliance.

Power, water, and after the utilities fail

Appliance Power Water After grid fails
Clothing Dryer Required Not required Generator power is enough. No plumbing step.
Washing Machine Required Required Need power and a water supply on the machine (plumbed rain collector / valid pipe connection when the municipal supply is gone).
Combo · dryer mode Required Not required Same as a standalone dryer.
Combo · washer mode Required Required Same water rules as a washing machine.
Plumbing is for wash mode, not dry mode Only laundry objects that need fluid (washer / combo washer mode) care about water piping after the city supply shuts off. Hooking a rain collector and plumbing is about cleaning, not about running a dryer. For collectors and generators, see rain collectors and generators.

Moving laundry machines to your base

Washing machines, clothing dryers, and combo washer/dryers are heavy metal appliances you can relocate:

  • Electrical skill 3 required to pick them up
  • Need an electrician-type tool for pickup and placement
  • 20-slot container capacity when installed
  • Very heavy—plan inventory space or a vehicle before hauling

Train Electrical before you try to relocate a full laundry setup. Related skill guide: level Electrical.

Optional mod: Wring Out Clothing (Build 41 only)

Not a Build 42.19 recommendation The Steam Workshop item Wring Out Clothing is listed for Build 41 only (last Workshop update around 2023-08-23). Prefer vanilla natural drying or a powered dryer on current B42 saves. If you still use it on an old B41 world, treat wringing as a wetness shortcut only—it does not replace washing blood and dirt.

Practical loadout tips

  • Carry a dry spare shirt/jacket so rain or a post-wash wet layer does not strand you outdoors.
  • Keep soap near your main water source; hand wash without soap is painfully slow.
  • After fights, clean bloodied gear before long healing sessions if you have open wounds.
  • If power is gone but water remains, hand wash and air-dry. If water is gone but power remains, you can still dry—but not machine-wash until the washer has fluid again.

Common mistakes

  • Treating washing as a required step before drying.
  • Expecting a dryer to remove blood or dirt.
  • Plumbing a rain barrel “for the dryer” when only washer mode needs water.
  • Assuming any Electrical skill is enough to pick up machines—you need Electrical 3.
  • Treating wetness → cold and blood → wound infection as if they were one mechanic.
  • Installing a B41 wring-out mod on a B42 save without checking compatibility.
