Powerful formula for Engine Cleaning.
THE POWERFUL FORMULA PENETRATES AND DISSOLVES STUBBORN DIRT AND GRIME, LEAVING BEHIND A CLEAN AND REFRESHED ENGINE BAY.
The Hermosa Engine Cleaner combines glycerol, a versatile solvent that dissolves dirt and grease, with AES (Alcohol Ethoxysulfate), a surfactant that lifts and suspends contaminants. Together, they effectively remove dirt and grime, restoring the engine bay to its pristine condition.
What’s in Hermosa Engine Cleaner?
Engine cleaners are formulated with a combination of active ingredients designed to effectively dissolve and remove dirt, grease, oil, and grime from engine surfaces. These ingredients typically include solvents, surfactants, and other additives to enhance cleaning performance and protect engine components.
In the case of Hermosa Engine Cleaner, the powerful formula contains two key ingredients:
-
Glycerol (Glycerin): Glycerol is a versatile compound known for its solvent properties. It effectively breaks down tough stains and buildup on engine surfaces, making it easier to remove dirt, grease, and grime. Glycerol acts as a solvent, dissolving contaminants and facilitating their removal during the cleaning process.
-
AES (Alcohol Ethoxysulfate): AES is a surfactant commonly used in cleaning products for its excellent cleaning properties. It works by lifting and suspending dirt and grime from the surface, allowing them to be easily rinsed away. AES is particularly effective in removing oil, grease, and other tough stains from engine surfaces, contributing to the overall cleaning power of the formula.
Together, these ingredients work synergistically to dissolve and remove dirt, grease, oil, and grime from the engine surfaces, leaving them clean and refreshed.
Additionally, they help to protect engine components and maintain the overall cleanliness and performance of the engine bay.
Frequently Asked Questions
To use Hermosa Engine Cleaner, begin by ensuring the engine is cool and the surface is dry.
Spray the cleaner directly onto the engine components, allowing it to penetrate and emulsify the dirt and grime.
Use a brush or sponge to agitate stubborn areas if necessary.
After letting it sit for a few minutes, rinse off the cleaner thoroughly with water.
For heavily soiled areas, you may need to repeat the process.
Finally, dry the engine bay with a clean microfibre towel to prevent water spots.
Yes, Hermosa Engine Cleaner is safe for use on various engine components, including rubber hoses, plastic covers, and metal surfaces.
Its gentle yet effective formula is specially formulated to dissolve and remove dirt, grease, and grime without causing damage to sensitive engine parts.
However, it's always recommended to test the product in a small, inconspicuous area first to ensure compatibility.
The frequency of using Hermosa Engine Cleaner depends on several factors, including driving conditions, climate, and the level of dirt buildup.
As a general guideline, it's recommended to clean your engine bay every 6 to 12 months or as needed.
Regular maintenance will help prevent dirt and grime buildup, ensuring your engine bay stays clean and well-maintained.
It is not recommended to use Hermosa Engine Cleaner on hot engines.
Applying the cleaner to a hot engine can cause it to evaporate too quickly, reducing its effectiveness and potentially leaving behind streaks or residue.
To ensure optimal results, always use the cleaner on a cool engine and allow it to penetrate and emulsify the dirt and grime before rinsing thoroughly with water.
While Hermosa Engine Cleaner is safe for use on most engine components, it's advisable to take precautions to protect sensitive electrical components from direct exposure to water or cleaners.
Covering exposed electrical connectors or delicate wiring with plastic bags or tape can help prevent moisture from causing damage during the cleaning process.

Step 1
Wait for the car to cool down if it has been driven recently (wait at least 30 minutes if the wheels or hood are hot).
Once the vehicle is cool to the touch, put on your gloves and lets go!
Step 2
Spray the Hermosa Engine Cleaner directly onto engine components. Allow the cleaner to penetrate and emulsify dirt and grime for 1-2 minutes. Use a brush or sponge to agitate stubborn areas if needed.
Step 3
Thoroughly rinse off the cleaner with water. Do not use a high-pressure hose or water blaster in the engine bay as this can cause water ingress into electrical connections. Repeat the process for heavily soiled areas if necessary.
Step 4
Dry the engine bay with a clean microfiber towel to prevent water spots.
