Dealing with Arthur Morgan's hygiene is now much easier.
In Red Dead Redemption 2, the developers introduced many diverse mechanics. There are also elements of "survival."
Under normal circumstances, the hero in RDR 2 can wash in a hotel or swim in a river, but modder saul0097 offered an immersive and more effective solution to the problem of dirt — he added the ability to wash in the nearest available body of water.
Washing will give a temporary bonus to stamina, and for the sake of balance, a 6-hour cooldown has been set for it (you can still wash during this period).
The Wash Yourself modification for Red Dead Redemption 2 is available for free on Nexus Mods.
