SPRAY
Pre-wet the bike. Mist Dirtii across frame, drivetrain, and parts. Let the formula reach the grime first.
DIRT IS TEMPORARY
SPOTLESS / CERTIFIEDOriginally developed for avionics. Now available for your everyday bikes.
Avionic desined cleaner for your bike.
DIRTii / GROUND CREW
FILTH
MEETS ITS
MATCH
THE BOTTLE IS FOREVER
You buy the sprayer once. After that, only a 2 oz concentrate returns to fill it back up. Less plastic made, less plastic shipped, and one permanent bottle that never hits the landfill. Our goal is to provide the best product on the market while reducing and minimizing waste. We offer refills so you never have to throw your spray bottle away.
You get the same high quality performance in your cleaner that is designed for avionics.
That is not a metaphor. Dirtii was originally developed to clean aircraft and precision components. Bike Edition puts the same professional-grade formula in a bottle you keep forever.
PRE-FLIGHT. POST-RIDE.
AGITATE
Work it with a soft brush. The foam lifts dirt, grease, and trail residue off the surface instead of grinding it in.
RINSE
Low-pressure rinse, air dry. For the next level of clean, wipe down with a microfiber. That is the whole ceremony.
AVIATION-GRADE CHEMISTRY
Originally developed to clean aircraft and precision components, engineered to the highest technical standards. Now tuned for the machines you actually ride: carbon, alloy, e-bike drivetrains, matte finishes, discs. It lifts grime off the surface and rinses clean, so what should shine, shines.

FIELD REPORTS
Sprayed it on a bike that had no business being that dirty. Rinsed off like the mud gave up.
Finally a cleaner that treats an e-bike like an aircraft: battery out, low pressure, spotless.
No film, no streaks on the matte frame. It just looks factory again.
The bottle alone upgrades the shelf. The clean is why it stays.
WHY NOT DISH SOAP?
| SPEC | DIRTII | DISH SOAP | BIG-BOX SPRAY |
|---|---|---|---|
| MADE FOR BIKES | Yes, engineered for frames, drivetrains, and finishes | Made for dishes; salts and degreasers can be harsh on parts | General purpose, generic result |
| RESPECTS YOUR LUBE | Cleans grime without stripping what should stay | Strips lube and protectants along with the dirt | Unpredictable |
| FINISH | Rinses clean, no film, no swirl marks | Residue can linger on parts and rotors | Often leaves gloss agents behind |
| THE BOTTLE | A sprayer you keep forever, refilled not rebought | N/A | Disposable, every time |
| COST PER WASH | About $1 | Cheap now, hard on components later | Comparable, without the bike-first formula |
JOIN THE GROUND CREW
One bottle, built for the long haul. The first fill is in it. The ritual comes with it.
BEFORE YOU ASK
Straight answers, no hangar talk.
IS THE AVIATION STORY REAL?
Yes. Dirtii was originally developed to clean aircraft and precision components, engineered to the highest technical standards. Bike Edition brings that professional-grade formula to your machine, trusted where it matters most.
IS IT SAFE ON CARBON AND MATTE PAINT?
Yes. Used as directed, Dirtii is made for carbon fiber, alloy, paint, matte finishes, rubber, and plastics. Spray, agitate, rinse; nothing on the bike gets attacked in the process.
WHAT ABOUT MY DISC BRAKES?
Dirtii rinses completely and leaves no film behind. Standard good technique still applies: rinse thoroughly and do not soak pads directly. Clean bike, quiet brakes.
IS IT E-BIKE SAFE?
Yes, with e-bike rules: battery out or covered, display off, low-pressure water only, never a pressure washer, never wash the bike upside down, reinstall the battery dry. Dirtii is made for e-bikes, mountain, road, gravel, BMX, stationary bikes, and your tools.
WHY NOT JUST DISH SOAP?
Dish soap is built for plates: its salts and aggressive degreasers can promote corrosion, strip the lube and protectants you want to keep, and leave residue where you least want it. A bike-specific wash lifts grime and leaves the rest alone.
WILL IT LEAVE RESIDUE OR STREAKS?
No. It rinses clean with no film and no swirl marks. For a next-level finish, wipe down with a microfiber after the rinse.
