Mouthwashing has 18 achievements on Steam and 16 on Xbox and PS5, where the PS5 list adds a Platinum trophy for earning the rest. Two unlock just by playing, and almost every other one is tied to a single moment in a single chapter, so the quickest route to 100 percent is one careful playthrough that follows the list below in order.
The two extras on Steam, Developer and Any% Glitched, both need the PC version’s hidden Developer menu, and neither is on the console lists. The Switch version has no achievements, since Nintendo’s consoles have no achievement system. Below is every achievement in the order you can earn it, with Steam’s own description and how many Steam players have it, then how to get each one, the Steam-only pair, the points of no return, and what to do when an achievement will not unlock. Story spoilers are kept to what each step needs, and nothing here gives away the ending.
Every Mouthwashing Achievement in Order
Each chapter opens with a time card that tells you where you are in the story, so the table gives the chapter number, the time card or both. The percentages are Steam’s global achievement stats as of November 7, 2026.

Twelve of the 18 are hidden on Steam until you unlock them; only the opening achievement and the five employee cards show their descriptions from the start.
The Two Story Achievements
- I Hope This Hurts unlocks the moment you start the game.
- Go Home unlocks when you finish it. Mouthwashing has one ending, so there is nothing to choose, as our guide to how many endings there are explains.
These are the only two you cannot miss.
The Five Employee ID Cards
Each crew member’s card turns up once, in one chapter. Look before you move the story on.
- Anya: in the opening chapter, you open the cockpit locker to get a key. Look inside before you leave: her card is stuck to the left side of the locker. This is the only chance.
- Daisuke: in the “3 Months After the Crash” chapter, Jimmy wakes in the lounge and is told to check on Curly. Before you leave the lounge, check the small table in front of the couch. The card is next to the board game.
- Swansea: in the “4 Months After the Crash” chapter, Swansea is in the lounge, dancing with the axe. Go to the broken vending machine in the back right corner and check its dispenser slot.
- Jimmy: in Chapter 16, while you make the spiked drink for Swansea, check the hat on the broken Polle statue in the lounge. Grab it before you finish the drink. Our guide to knocking out Swansea covers the recipe.
- Curly: in Chapter 19, when you search the Utility room, the card is on the floor beside the only working cryo pod. Pick it up before you open the gun case in Medical, because opening the case moves the story on.
The Missable One-Scene Achievements
- Sock Puppet: in Medical, interact with Curly, then interact with his chin to zoom in, and keep opening and closing his mouth for about 10 seconds. The first chance is the “2 Months After the Crash” chapter, and the scene where you give him painkillers, three months after the crash, is a backup.
- Cheater: in Chapter 2, enter 4517 on the cargo door keypad before you pick up the Code Scanner from the cockpit floor. The code never changes, which is the whole trick. Our Code Scanner guide has every code in the game.
- Yimpy: in Chapter 4, after Curly’s psych evaluation with Anya, walk up to the corkboard in Medical before you leave. Zoom in on the sticky note with a crude drawing labelled “Yimpy” and keep looking for at least 10 seconds. Wrong Organ’s first Q&A post says Daisuke drew him in the story. This is the same chapter where you get Daisuke out of the foam.
- Friendly Introduction: after the cockpit talk with Jimmy and the message from corporate, Curly ends up in a dark warehouse with an old TV. Do not use the TV yet, because it moves the story on. Walk past it to the storage shelves behind, look through the gaps between the boxes, and keep looking at the bandaged figure staring back until he vanishes with a loud noise.
- Wasteful: at Curly’s birthday party in Chapter 7, make the mocktail before you finish the cake. Mix water (3142) and tonic (1324) into a drink base, then mix the base with sweetener (2341). Our cake guide walks through the mixing machine.
- The Name Of The Game: open your inventory, select a bottle of mouthwash and choose to use it. The first bottle comes from Daisuke, lying in the corridor in the “4 Months After the Crash” chapter, and any bottle works up until you mix one into Swansea’s drink in Chapter 16.
- Taking Notes: in Chapter 19, open the gun case (the Pony Express Protection Kit) in Medical with code 739 without setting foot in the cockpit during that chapter. Since the code never changes, type it straight in. Get Curly’s card first.
The Graveyard Pair
Near the end, in a hallucination chapter titled Bizarro Chapter 1, Swansea hunts you through a graveyard with an axe while you carry a gun. The fight ends after a few hits, so the order matters.
- The Good Ending: let Swansea kill you 10 times without firing. He attacks from the side you are not facing, so standing with your face to a wall is quickest. You respawn after each death, and the name is a joke, not an ending.
- Trickshot: after that, hit Swansea with a shot fired right after a full 360-degree turn. Our guide to the Trickshot achievement has the full method, the reasons it fails and what to do if the fight ends without it.
The Two Steam-Only Achievements
- Developer: press the tilde key (~, the key under Esc) to open the Developer menu, or press L3 and R3 together on a controller, a shortcut Wrong Organ added in its first patch. If the key does nothing, right-click Mouthwashing in your Steam Library, choose Manage, then Browse local files, open LaunchOptions.dat in a text editor, change “ConsoleEnabled = false” to “true” and restart the game.
- Any% Glitched: this one needs cheats and speed. Open the Developer menu, turn cheats on and load Chapter 14 from the chapter list, which starts the 35-second clock. Hold P to skip the dialogue, switch on the Code Scanner so you can see, then press O for no-clip and drop straight through the floor toward the Polle statue holding a bottle of mouthwash below you. Hold Shift to move faster, and take the bottle before the time runs out. If it does not unlock, restart the game and try again.
Which Achievements Are Missable
On console, 14 of the 16 are missable: everything except I Hope This Hurts and Go Home. On PC, the Developer menu’s chapter list lets you go back for anything you missed, as our guide to how to save in Mouthwashing explains. We could not confirm a chapter select on PS5 or Xbox, and Wrong Organ has not said whether the console versions keep the Developer menu, so on console a miss means another run of about two to three hours, per our how long to beat guide.
The points of no return to watch:
- Anya: before you leave the cockpit in the opening chapter.
- Cheater: before you pick up the Code Scanner.
- Friendly Introduction: before you use the TV.
- Wasteful: before you finish the cake.
- Jimmy: before you finish Swansea’s drink.
- Curly and Taking Notes: before you open the gun case, and stay out of the cockpit for that whole chapter.
- Trickshot: before the last hit lands in the graveyard.
Mouthwashing Achievements Not Unlocking
- Update the game. Wrong Organ’s first patch, a week after the September 2024 launch, “Fixed achievements not unlocking properly,” and a January 2025 update “Finally removed the ability to wipe your achievement progress by accident.”
- Check the list before you replay. A notification that never appears does not always mean the achievement failed. Look at the achievement list in Steam or on your console first.
- Restart the game. If something you clearly did still shows as locked, close Mouthwashing and open it again before you decide it failed.
- Mind the clock on Any% Glitched. The 35 seconds start when Chapter 14 begins, so dialogue you do not skip eats into them.
- Turn cheats off for the rest. Developer and Any% Glitched need the menu, but switch no-clip and other cheats off before you go after anything else, so a cheat never gets in the way of an unlock.
