Clean Your Keycaps Soap Tier List
Rinse and polish upgrades ranked by timing, not hype.
Soap upgrades control the second half of the Clean Your Keycaps wash loop: rinsing grime away and polishing keycaps until they sell for full value. 2 da moon! advertises both sponges and soap in the official description because neither stat alone carries a run. Buy soap too early and you starve sponge tiers that gate scrub speed. Buy soap too late and fast scrubbing turns into a rinse bottleneck.
This soap tier list ranks purchases by when they pay off, using the same S-through-D scale as the Sponge Tier List. Exact soap names in the Roblox shop can change between [UPD] patches; tiers here refer to recognizable progression bands — starter soap, first real rinse upgrade, mid-tier polish boosters, late-game soap, and pre-rebirth cap rows. Always confirm live stats after updates on Latest Update Notes.
How soap differs from sponges
Sponges attack the scrub step where you first touch dirty keycaps. Soap improves rinse and polish, which determine how quickly a batch becomes sell-ready. In incremental simulators like this one, the slowest step in the cycle is your real bottleneck. Soap tiers are S-tier when they shorten that slowest step; they are D-tier when scrubbing still dominates your timer.
A practical test: run one full batch and note which phase eats the most seconds. If scrubbing wins, soap can wait. If rinse or polish wins, the next soap tier jumps toward S-tier immediately.
S Tier — High value when timed correctly
First soap tier after your second sponge upgrade. For most new accounts, the opening soap purchase becomes S-tier once two sponge jumps are in place. That is the point where polish time often shows up on mental radar.
Next affordable soap while rinse is the slowest step. When your timer test says rinse or polish leads, treat the next soap row like sponges: buy on sight if you stay cash-positive.
Soap tier paired with worker unlock. Workers automate washing tasks. If automation exposes polish as the new bottleneck, the soap tier that targets polish speed is S-tier for that session even if it was B-tier yesterday.
Mid-game soap band before rebirth. The middle price band — where each tier shaves a visible chunk off rinse time — stays S-tier until costs outpace plot income for more than one short grind session.
A Tier — Buy soon, not first
Second and third soap tiers in sequence. After the first meaningful soap upgrade, the next one or two tiers are usually A-tier assuming sponges are not lagging more than one band behind.
Soap rebuy chain after rebirth. Rebirth resets parts of your toolkit. Rebuilding soap along the shop list is A-tier because you are restoring full-cycle speed on multiplied income.
Event or update buff windows. When [UPD] patches buff soap or add limited tiers documented on Updates, new rows can sit at A-tier even if old guides ranked them lower — verify in-game before bulk buying.
B Tier — Situational picks
Soap bought before any sponge upgrade. Viable only if the tutorial or a starter bundle gave you a free sponge jump. Otherwise this is a B-tier delay to your first real speed gain.
Skipping one soap tier to afford sponge. Acceptable when scrub time is still double rinse time. Compare against the Upgrade Priority chart before skipping.
Late soap while placement income lags. If clean keycaps pile up unsold because plot slots or carry time lag, fixing income may outrank soap for one grind block — B-tier, not D-tier.
C Tier — Low urgency purchases
Max soap tier minutes before rebirth. Like sponges, dumping all cash into the final soap row instead of rebirthing when multipliers are ready is often C-tier. Run the rebirth math on the priority page first.
Cosmetic soap skins without stat bumps. Color swaps that do not change rinse or polish speed are flex buys.
Soap when you still manually scrub slower than auto-wash scripts. Official gameplay assumes fair progression. Third-party automation from the Scripts hub does not change tier logic for legitimate players and carries ToS risk.
D Tier — Traps to avoid
Max soap at account creation. Starter cash belongs in sponges. Soap-first strategies feel satisfying visually but extend the first hour unnecessarily.
Alternating soap-sponge every single purchase. Strict alternation ignores whichever step is actually slowest. Responsive buying beats pattern memorization.
Ignoring soap entirely until endgame. Players who never invest in rinse speed hit a wall where scrubbing is instant but batches still take minutes to finish — a D-tier grind trap.
Soap vs sponge — quick reference
| Your bottleneck | Buy first |
|---|---|
| Scrub phase longest | Next sponge tier |
| Rinse phase longest | Next soap tier |
| Polish phase longest | Next soap tier with polish stat |
| Plot not full | Placement / income upgrades |
| Manual time minimal | Workers, then rebirth prep |
Suggested soap progression (first rebirth)
- Complete How to Play and earn your first sales.
- Buy two sponge tiers minimum.
- Run a timed batch — if rinse or polish leads, buy first S-tier soap row.
- Resume sponge → soap rhythm guided by timer tests, not shop order alone.
- Before rebirth, ensure neither tool lags more than one band behind the other.
- Use Upgrade Planner to set cash targets if you lose track.
Patch awareness
Soap rebalances often accompany sponge changes in incremental Roblox titles. After any [UPD] tag refresh, redo one timed cycle. If polish got faster globally, older soap tiers may drop a letter until prices adjust. We document verified shifts on Latest Update Notes without fabricating version numbers.

Frequently Asked Questions
Quick answers for Clean Your Keycaps players.
When should I buy my first soap upgrade?
Usually after your second sponge tier, once scrubbing is no longer the slowest part of the wash loop. Time one full batch if you are unsure.
Is max soap better than max sponge?
Neither maxes in isolation. The best tool is whichever shortens your current slowest step. Most early runs need sponge levels first; mid-game runs alternate both.
Does soap affect sell price or only speed?
Soap tiers primarily speed rinse and polish so batches finish faster. Faster cycles mean more sales per hour, which raises effective income even if per-keycap price stays flat.
Do soap tiers reset on rebirth?
Rebirth resets parts of progression depending on current game rules. Plan to rebuy soap along the shop chain after rebirth the same way you rebuy sponges.
