Spring events in Arknights: Endfield usually come with a bit of busywork, but Cleanse and Rinse is one of the easier ones to enjoy. If you've already cleared the Wuling story and finished Where Danger Sleeps, you can jump straight in once the Wuling AIC is unlocked. A lot of players who are getting settled into the game, or even checking out an Arknights endfield account Buy option to catch up faster, will find this event pretty approachable. It runs from March 29 to April 19, 2026, and the setup is simple: open the Events tab, read Chen Qianyu's message, then head to the northern side of the Residential Area to speak with Auntie Yu. She kicks off the whole sanitation drive, and from there it's all about turning your drone jet into the hardest-working cleaning tool in Wuling.



How the event unlocks day by day
There are seven mini-quests in total, released in order from March 29 through April 4. So yes, you can log in each day and chip away at them, or you can leave them for a few days and clear the full set in one go. That's probably what a lot of people will do. The event itself doesn't ask for anything fancy once you're in. Just take the assignments from Auntie Yu, equip the Spray drone jet, fill it with Clean Water, and start washing away those muddy brown stains stuck to walls, platforms, corners, and sometimes creatures that clearly didn't have a great week. You'll know you're on the right track when the objective counter starts moving. One small thing that's easy to miss: every use of Clean Water adds Aluvium Bottles to your inventory, so if your bag's already packed, clear some room first.



What you'll actually be doing
The mission list gives the event a nice bit of variety, even if the core loop stays the same. Cold Shower has you cleaning Burdenbeasts, while Critter's Trail focuses on those awkward pawprints left behind in spots you might've ignored before. Then you move through Reign of Gloomy Dirt, Chubby Lung Rescue, Hidden Danger, Platform Cleaning Drill, and Bouncy Cleaning Drill. None of them are especially hard, but they do push you around the map in a useful way. If you still have fogged-over sections or haven't fully learned the layout of Qingbo Stockade and Wuling, this event nudges you into that naturally. It doesn't feel like a grind so much as a reason to wander, spray a few targets, and tidy up as you go.



Why the rewards are worth your time
The rewards are the real hook, and honestly they're solid. Each stage gives between 200 and 300 Oberyl, which makes the total payout feel pretty generous for an event built around quick daily tasks. On top of that, you'll pick up an Advanced Progression Selection Crate 1, Advanced Cognitive Carriers for operators past level 60, Marks of Perseverance for skill upgrades, plus a good chunk of T-Creds and extra blue and purple materials. There's also a cosmetic side to it, which a lot of players care about more than they admit: the Totally Cleansed and Rinsed medal and the Expert Cleaner profile portrait are both nice keepsakes.
