Engine care & cleaning

(127 products)

Regular maintenance and cleaning of your boat engine contributes significantly to its performance, longevity, and operational reliability. Preventing corrosion and deposits early on is especially important in salty environments or during extended storage. In our online shop, you'll find everything you need for thorough engine cleaning and care.


  • Protection against salt, oil and deposits

    Salt deposits, fuel residue, and contaminants can significantly damage a boat's engine. Fuel system cleaning additives, special engine cleaners, and salt removers help protect sensitive components and reliably remove residues. This applies to both inboard and outboard engines.

  • Cleaning and care products for every engine type

    Whether diesel or gasoline engine, built-in or outboard – with the right care products, all engine types can be effectively treated. Special sprays protect electrical contacts from moisture, preserve metal parts, and prevent surface corrosion. Products for the care of the drivetrain, ignition system, and fuel injectors are also included.

  • Preserve your engine – especially before winter storage

    Before winter storage, a thorough preservation is recommended. Fogging oils protect the engine's interior from corrosion. Flushing with fresh water or special flushing additives is also part of the maintenance before extended periods of downtime—especially for outboards that have been operated in saltwater.

  • Everything for cleaning and care in one range

    From engine care sprays to demineralization cleaners to fuel system cleaners – at awn, you'll find a selection of proven products for professional engine care. You can also conveniently purchase accessories such as mixing containers, cleaning hoses, and dosing aids online.
