How to clean car engine

I have over the years owned quite a few cars ranging from second hand to brand new and one thing stayed constant – I love a Clean Car Engine.

Currently we own a used 2004 VW Polo Classic which is serving us well. Even though the vehicle is old there is no need to neglect the engine and engine bay.

First a Warning! Most vehicle manufacturers design the engines to be more or less water resistant with plastic covers over the vital areas. Care should be taken when washing your engine with water. Make sure that all electronics and connectors are covered before spraying your engine.

You don’t want to sit with a sparkling engine that is dead or refuses to start.

First step to a clean car engine.

Firstly I use a hosepipe with a nozzle that allows a strong water jet to wash off all the loose grime. Spray the engine bay and engine as well as the bottom side of the bonnet.

My next step is a spray bottle filled with my favorite all round cleaner – Cleen Green. The cleaner is not diluted in the spray bottle as its full strength is needed.

The whole engine and engine bay is sprayed quite generously with the cleaner. Take care not to get any on the cars paint work. Wipe it off straight away if it does get on the exterior paint surface.

Next comes the bucket filled with a diluted mixture of Cleen Green and water. Use a sponge and brush to wash the areas to get rid of all the built up grime. Spray the areas again if needed.

Once you are satisfied that everything is clean – use your hosepipe with the nozzle to spray the engine.

Use a chamois cloth to dry the covers, engine and engine bay as much as possible. I normally start the motor and take the car for a short drive to get the engine warm and dry.

The Final Treatment

Once the engine bay and engine is dry look for any areas that are still not completely clean and use the Cleen Green spray and a dry cloth to clean the areas.

Finally, I use Silicone Spray to spray all the plastic covers and rubber pipes etc. Let the silicone soak into the areas for about an hour and then wipe off and buff.

Your engine should look brand new. It is also easier to spot oil leaks when its clean and also a pleasure to work on.
