Cleaning a Dirty Snowmobile Engine

Frolicking across a snow-covered landscape on a winter afternoon is an exhilarating activity. Bouncing over snowy hills gets the adrenaline pumping and the blood circulating, even in the coldest temperatures. After all of the snowmobiling is done, though, the cleanup must begin. Whether storing a snowmobile after winter yields to spring, or simply cleaning it off until the next outing, removing dirt and grime from the engine is very important. Keep your snowmobile clean and ready for your next trip.


1) Spray the snowmobile with water from hose with a spray nozzle to remove as much dirt, ice and grime as possible. Using a pressure washer can damage delicate parts.

2) Start the snowmobile and let the engine warm up for a few minutes. This will help bake the engine cleaner on the engine, removing more tough dirt and grime.

3) Turn off the snowmobile and thoroughly spray the engine with a foaming degreaser, like GUNK Foamy Engine Brite. Let the degreaser set on the engine for at least five minutes.

4) Scrub any heavily soiled areas of the engine with a brush or sponge. A second treatment of engine degreaser may be necessary on these areas.

5) Spray the engine thoroughly with cold water to remove the engine degreaser. Pay special attention to the bottom of the engine and areas that are not initially visible. Wipe the engine down with a towel/cloth.

Extra Tips:

* Dish soap can also be used instead of engine degreaser. It may take several applications to remove the dirt and grime, but dish soap can be effective.

* Wipe the entire engine with a dry cloth or towel after cleaning it. A film from the engine degreaser can remain if it is not wiped off.

* Be careful when spraying water near the carburetor, air filter and ignition. These areas do not need to come in contact with excess water at higher pressures.
