If you are wondering if cleaning your clothes does anything in Xenoblade Chronicles 3, the answer is no—at least, nothing substantial. In short, the option to clean clothes in Xenoblade is purely cosmetic and immersive. Because of this, cleaning your clothes will only do just that—clean your clothes and remove any dirt and dust. It will not give you any stat boosts. After using the Clean Clothes option at Rest Spots, your clothes will just look new and clean.
How to clean your clothes in Xenoblade Chronicles 3
To clean your clothes in Xenoblade Chronicles 3, you must first locate a Rest Spot. Rest Spots are unique locations that you find via their unique hand-shaking icons. Once you locate a Rest Spot in XC3, you can use the Clean Clothes option to rest.
To rest at a Rest Spot, just walk up and press the A key. Doing so opens up the Rest Spot menu, where you can find the option to Clean Clothes, usually on the right of the other options. However, only specific Rest spot locations, like Barracks and spots in the Open world, have the Clean Clothes option. Canteen Rest Spots don't have it.
Where to find Rest Spots in Xenoblade Chronicles 3
To find Rest Spot locations in Xenoblade Chronicles 3, you must search for hand-shaking icons like the one above. That said, these unique icons mark where you can find a Rest Spot. Usually, there will be at least one or two Rest Spot locations that you can find in an area. Colonies will also have Rest Spots that you can use for various utility options.
