Mouthwashing Achievements: All 18 and Missable Tasks

Mouthwashing has 18 Steam achievements in the official English schema checked on October 24, 2026. Collect five employee cards, finish the story, and complete the optional interactions and special-condition tasks below. Older references listing 11 achievements do not describe this current list.

Full story and ending spoilers follow. The checklist names disturbing interactions, a lethal graveyard encounter and the final cryopod scene. For ordinary progression, use the walkthrough; for interpretation after finishing, read ending explained.

Achievement names and triggers below come from Steam's official list. Environmental locations come from the player-authored guides by Dess and 伏双双. Their walkthrough advice is community documentation, rather than a developer guarantee or a firsthand test by this site.

01

All 18 achievements at a glance

The current schema has six public achievements and twelve hidden ones. Hidden status conceals a description in the achievement interface; it does not imply a separate story branch.

02

Begin with Anya, Cargo and Curly's mouth

I Hope This Hurts belongs to starting the story. Before leaving the opening cockpit, inspect the locker on the right for Anya's employee card. Interact with the card; simply being in the correct room is not the condition.

During the early post-crash exploration, Cheater requires a different order from the normal puzzle route. Go to Cargo and enter 4517 before acquiring the Code Scanner. Collecting the scanner first and then entering the correct code still opens the door, but misses this achievement's stated prerequisite.

In medical, inspect injured Curly. Sock Puppet asks for repeated opening and closing of his mouth. The official trigger does not publish a precise repetition count, so a claimed universal number of clicks would be unsupported. Treat this separately from administering his painkillers for story progression.

03

Find Yimpy and the television visitor

During the pre-crash medical evaluation as Curly, look behind Anya at the noticeboard. The community guides place Yimpy there. Keep looking at the figure for the official ten-second duration before continuing toward Jimmy and Swansea.

For Friendly Introduction, use the surreal storage-room scene with a television as your landmark. Explore beyond the television and inspect the dark gaps between the shelves for Curly. This is a discovery interaction, rather than an instruction to complete a particular television channel sequence. These scene descriptions are more useful than sorting the game's deliberately nonlinear events by date.

04

Make the birthday mocktail and collect Daisuke's card

For Wasteful, make the mocktail at Curly's birthday before serving the cake. Obtain Water with dispenser code 3142, Tonic with 1324, and Sweetener with 2341. Combine Water and Tonic, then add Sweetener to the resulting base.

The mocktail and birthday cake are separate recipes. Making Cake Base with Gelatin does not satisfy the mocktail condition. The cake puzzle guide shows both preparations so you can complete the optional drink before advancing the party.

In the lounge scene after the birthday sequence, inspect the small board-game table for Daisuke's employee card. Both the room and the object matter: this card is not obtained merely by speaking with Daisuke elsewhere aboard the Tulpar.

05

Use mouthwash and inspect the broken machine

In the post-crash scene where Daisuke is lying outside Cargo, take the mouthwash bottle and use it from your inventory for The Name Of The Game. Possessing the bottle and using it are distinct actions in the official condition.

Next, inspect the lounge's broken drink machine near Swansea and the large screen. Swansea's employee card is inside a damaged machine. The dancing scene is the community guides' useful location cue; it separates this visit from later scenes in which Swansea guards the utility-room entrance.

06

Collect Jimmy and Curly, then remember 739

During the later lounge objective involving the spiked drink for Swansea, inspect the damaged Polle figure and its hat behind the table for Jimmy's employee card. Search before focusing entirely on the drink ingredients.

After the utility-room events, inspect the floor beside the remaining cryopod for Curly's employee card. The English community guide places it to the left of the pod during the late return to this area.

For Taking Notes, enter 739 at the medical Protection Kit without returning to the cockpit during that objective. The usual clue is inside the cockpit locker, but fetching it at this point defeats the special condition. Use the gun-case code guide to distinguish obtaining the weapon from earning the achievement.

07

Separate the graveyard tasks from the story ending

The Good Ending requires ten deaths to Swansea in the graveyard. It is an achievement title, not evidence of an alternate happy ending or a route that saves the crew. Attempt its death count before finishing the encounter if it remains on your checklist.

Trickshot requires a complete camera rotation immediately before hitting Swansea. The source guides describe him approaching from behind and recommend watching the encounter's warning cues. They do not establish a guaranteed timing window for every player. Plan attempts before landing the shots that advance the scene.

Go Home is the completion achievement. Continue through the remaining surreal sequences to the final action of placing Curly in the cryopod. Neither this achievement nor the graveyard title confirms a later rescue.

08

Reserve Developer and Any% Glitched for focused cleanup

Developer has the official condition of opening the developer console. Keyboard layouts, versions and console behavior can differ; no untested cheat command or save-file modification is needed to state that condition here.

For Any% Glitched, the official target is 35 seconds from Chapter 14 starting, ending when you take Polle's mouthwash. Reject older instructions that substitute thirty seconds. Community guides describe console-assisted routes and inconsistent unlock reports, so this page does not promise a working exploit or a guaranteed shortcut.

Keep a checklist of missing names and their scene landmarks before replaying. Prioritize order-sensitive tasks such as Cheater, Wasteful and Taking Notes, then revisit cards and encounter challenges. Check Steam's achievement status after an attempt rather than assuming every notification appears immediately. Use each community guide's chapter labels alongside its pictured environment; internal chapter numbers are not chronological story order.
