Wuling City's got that lived-in look right now, and the Cleanse and Rinse event gives you a good reason to slow down and sort it out. If you've already cleared the Wuling story and finished Where Danger Sleeps, you can jump straight in from the Events tab, or even buy Arknights endfield account if you're trying to catch up faster and don't want to miss limited-time stuff. The event runs from March 29 to April 19, 2026, and it starts with a message from Chen Qianyu about Sanitation Day. From there, head to the north side of the Residential Area and find Auntie Yu. She's the one handing out the work, and the whole thing kicks off with a pretty funny moment when she sees what your drone jet can do.



How the event is set up
There are 7 mini-quests in total, and they unlock one per day from March 29 through April 4. So yeah, you can do them as they appear, or just wait and clear everything in one go later. That part's pretty relaxed. Each task sends you out with the Spray drone jet, and you'll need to fill it with Clean Water before getting started. Then it's just a matter of tracking down the dirty spots around Qingbo Stockade and Wuling. Some of the grime is stuck to walls and platforms, while some of it shows up on creatures wandering nearby. You spray, keep at it for a few seconds, and the tracker updates once the target is fully cleaned.



What to watch out for while cleaning
The event sounds simple, and mostly it is, but there's one thing a lot of players will notice pretty quickly. Every time you use Clean Water, you'll pick up Aluvium Bottles, which can eat up bag space faster than expected. If your inventory is already crowded, sort that out first or you'll end up stopping halfway through. The 7 jobs themselves are varied enough to keep the routine from getting dull. Cold Shower has you washing Burdenbeasts, while Critter's Trail is more about clearing pawprints. Then you've got Reign of Gloomy Dirt, Chubby Lung Rescue, Hidden Danger, Platform Cleaning Drill, and Bouncy Cleaning Drill. A few of these send you into corners of the map you may not have fully explored, which is honestly part of the fun.



Why it's worth doing
The rewards are the real pull, and this event pays out well for something so low-pressure. Each stage gives 200 to 300 Oberyl, so by the end you've stacked up a decent amount of free currency. On top of that, there's an Advanced Progression Selection Crate 1, Advanced Cognitive Carriers for operators past level 60, Marks of Perseverance for skill upgrades, plus T-Creds and upgrade mats in both blue and purple tiers. You also get the Totally Cleansed and Rinsed medal and an Expert Cleaner profile portrait, which is a nice extra if you like event collectibles. It's not a difficult event at all, but it feels rewarding because every run leaves you with something useful.



A relaxed event with solid rewards
What makes Cleanse and Rinse work is that it doesn't ask for much. No stress, no messy gimmick, just a straightforward set of cleanup jobs that fit the setting surprisingly well. If you've been putting off exploring the last few foggy bits of Wuling, this is a handy excuse to do it.
