Version 1.1 has brought something a bit unexpected to Arknights: Endfield, and honestly, that's why the Cleanse and Rinse event lands so well. If you've been buried in route planning, fights, and all the usual pressure, this mini-event feels lighter from the minute you step in. A lot of players who follow guides have also seen it called Thorough Clean, but whatever name you use, the idea's the same. You're cleaning up Wuling City instead of smashing through another combat stage, and that switch in pace makes it oddly satisfying. For players already invested in progression, or even those looking into Arknights endfield boosting to save time elsewhere, this event is the kind of side content that's easy to slot into a daily routine without any stress.

How to unlock it

You don't need to jump through many hoops, but there is one story gate. First, clear Chapter II Process II: Where Danger Sleeps. After that, Wuling City opens on the map, and the event becomes available through the main Events screen. Hit the prompt, load in, and that's pretty much it. No special build. No gear check. No awkward prep work where you realise you're missing some random item. It's refreshingly direct, which suits the event itself. You get in fast, do the job, collect your rewards, move on.

What you actually do

The event starts with Auntie Yu, who's leading a city clean-up effort and handing out the jobs. From there, the tasks are simple in the best way. You'll scrub graffiti off surfaces, wash dirt from walls, and spray down Burdenbeasts that look like they've rolled through half the district. Dirty locations are marked clearly on the overworld map, so there's no pointless wandering. Once a mission begins, the game supplies the ferrium-treated Clean Water you need, and you use the Spray Tool or Drone Jet to finish each objective. You'll notice pretty quickly that these stages are built for short sessions. The first ones, like Critter's Trail and Cold Shower, go by in minutes, and more unlock over the following days.

Why players will actually bother

Let's be real, a low-pressure event only works if the rewards aren't rubbish. Thankfully, this one pays out well enough to matter. You can earn Oroberyl, Marks of Perseverance, and upgrade materials such as Advanced Cognitive Carriers, which makes the whole thing more than just a novelty. It's handy if you're saving for future banners or trying to strengthen a roster without another long grind. There's also an exclusive Expert Cleaner portrait waiting for players who finish the full event line, and that kind of cosmetic reward usually gets people to stick with it. More than anything, though, this event works because it doesn't ask for much and still feels worth doing.

A nice break before the next big push

Cleanse and Rinse isn't trying to be the headline feature of the patch, and that's probably why it works. It gives people a breather, keeps the login routine feeling fresh, and adds a bit of character to Wuling City at the same time. If you've been logging in just to clear stamina and dip, this is the sort of event that can pull you back for a few extra minutes without feeling like homework. And for players who like keeping their account progress moving from every angle, whether through event farming or checking game services on U4GM, it fits neatly into that wider routine while the heavier content is still warming up.
