CleenU product solution
Engine Degreaser
Water-based, nonflammable · Hoses off · Private label
Engine bay coated in black crud that hides leaks? Spray a fully cooled engine, wait 3–5 minutes, brush, and rinse with low-pressure water, and the grime washes away. Water-based and nonflammable, factory-direct private label.
- Small amounts of oil and transmission fluid seep from seals, road dust sticks, and engine heat bakes it into black crud on the block, oil pan, and lines. It hides leaks and hurts heat dissipation, and car wash soap won't move it.
- Solvent degreasers cut fast but smell strong, are flammable, and can be hard on hoses and plastic. This water-based alkaline formula is nonflammable, low-odor, hoses off, and includes an aluminum inhibitor. The keys: a fully cool engine and a prompt rinse, never letting it dry on the engine.

Before & after
Before and after (illustration)
Before: an eight-year-old engine bay with black crud around the valve cover and oil pan and sticky lines. After: sprayed cold, left 4 minutes, brushed, and rinsed, the crud is essentially gone and metal and aluminum show their original finish without whitening.
- Before: crud around valve cover and oil pan
- After cold spray, brush, rinse: grime gone
- Aluminum clean, no whitening
How it works
How engine grime washes away
Engine crud is oil and transmission fluid mixed with road dust and oxidized by heat. Alkaline builders saponify the oils into soluble soap, nonionic surfactants emulsify the rest, chelators free trapped particles, and the aluminum inhibitor protects alloy surfaces. Low-pressure water carries the emulsion away.
- Cool engine, cover electrics
- Spray bottom to top
- Saponifies and emulsifies grime
- Wait 3–5 minutes, brush
- Rinse with low pressure
Usage guidance
Use guidance
- Let the engine cool fully and bag the alternator, intake, fuse box, and exposed connectors.
- Spray greasy areas bottom to top, wait 3–5 minutes, and brush stubborn spots.
- Rinse with low-pressure water bottom up, then top down. Don't let it dry; dress plastic parts afterward if you like.

Why choose CleenU for Engine Degreaser?
From product positioning and samples to packaging and repeat supply, CleenU supports OEM/ODM projects built around Engine Degreaser.
Alkalinity tuned for aluminum
Modern engines use lots of aluminum, so we balance degreasing against corrosion protection to prevent whitening.
Concentrate and ready-to-use
Drivers prefer sprays and detail shops prefer gallon concentrate; mix formats by channel.
Sample testing that means something
We plan sample evaluation around engine bays of different ages and grime levels: dwell time, grease removal, aluminum whitening, and rinse residue.
Labels and documents ready
Bilingual label copy, SDS/MSDS, TDS, and batch COAs, with warnings and directions prepared for your target market.
Consistent reorders
Every batch is retained and issued a COA, so reorders match on color, scent, and feel.

Frequently asked questions (FAQ)
Find practical answers about Engine Degreaser, private label, samples, MOQ, documents, and delivery.
Product, use, and procurement
Why does so much grime build up under the hood?
Small amounts of oil and transmission fluid seep from seals, road dust sticks to them, and engine heat bakes it into black crud on the block, oil pan, and lines. It hides leaks and hurts heat dissipation.
Water-based or solvent degreaser?
Solvent degreasers cut fast but smell strong, are flammable, and can be tough on rubber and plastic. This is a water-based alkaline formula with an aluminum inhibitor. It's nonflammable, low-odor, and hoses off, which makes it the better pick for DIY in the driveway.
How often should I clean the engine bay?
Once or twice a year, or before tracking down a leak, selling the car, or doing mods. Off-road and dirt-road vehicles can go more often.
What should we decide first for a private-label engine degreaser?
Strength, applicator, and kit. Ready-to-use or concentrate (detail shops want gallon concentrates), trigger or foaming head (foam clings better on vertical surfaces), and whether to pair it with a trim restorer as a clean-and-dress kit.
How fast can we get samples and a first order?
Free samples ship in 3–5 days. MOQ is 500 bottles, and production is scheduled once packaging and labels are approved.
How does an engine degreaser actually work?
It breaks baked-on grease into tiny droplets that rinse away with water. The alkaline base softens oily grime, and surfactants surround the oil so it can't settle back onto the metal. That's why dwell time matters: spray a cool engine, let it sit 3 to 5 minutes, then rinse with low-pressure water before it dries.
Product usage questions
How do I prep the engine?
Make sure it's fully cool to the touch. Bag the alternator, air intake, fuse box, and any exposed connectors before you spray.
How long before I rinse?
Let it sit 3–5 minutes, scrub stubborn spots with a soft brush, and rinse with low-pressure water. Don't let it dry on the engine.
Can I use a pressure washer?
We don't recommend it. High pressure drives water into connectors and sensors. A garden hose is plenty.
Will it hurt aluminum or plastic parts?
Not when used as directed. The aluminum inhibitor helps, but the key is a cool engine and a prompt rinse. Dress plastic parts with a trim restorer afterward.
Can I use it on an EV's front compartment?
We don't recommend it; EVs have high-voltage parts, so follow the maker's guidance or use a pro.
Should I protect the bay afterward?
Yes. A plastic dressing restores the black finish and makes the next cleaning easier.
Can I wash the engine bay in winter?
Yes, above about 40°F; idle the engine a few minutes afterward to help it dry.
Is engine degreaser the same as brake cleaner or carb cleaner?
No—don't swap them. CleenU Engine Degreaser is water-based and meant to be rinsed off exterior engine surfaces. Brake and carb cleaners are fast-evaporating solvents made for brake parts and fuel-system internals, where no water or residue can be left behind. Degreaser or rinse water left on rotors or pads can affect braking.
Can I use it on paint, rubber hoses, and wiring?
Yes, as long as you rinse it off promptly and don't let it dry. If overspray lands on paint, rinse it right away. Hoses and wire jackets can be cleaned normally, but cover the alternator, fuse box, and any exposed connectors with plastic first, and test a small hidden spot the first time.
OEM/ODM customization questions
What can we customize?
Formula direction and strength, scent, fill size (500 mL spray, 1-gallon concentrate, and more), trigger or foaming head, label design and language, and kits with a trim restorer and engine brush.
How should we test samples?
Test section by section on engine bays of different ages and grime levels, and record dwell time, grease removal, any whitening on aluminum, and residue after rinsing. That tells you more than a before-and-after photo.
What paperwork comes with a private-label order?
Documents such as SDS/MSDS, TDS, COA, and label copy for your target market are prepared per project. We confirm which ones your order includes when we quote.
