HOW CLEANING DOWN

Diesel are easier to clean because there are no ignition components to suffer water ingress. But on all engines it’s vital to avoid directly soaking electrical connections and sensors. Use few polythene bags of various sizes to place over and protect these parts, then clean them individually after the main engine wash.

Before cleaning the engine proper, wipe and scrape the bulk of the dirt and mud away, preferably using a plastic scraper that won’t cause groove and scratches. Then start the first clean up using and engine degreaser. Brush it over every part, stippling with the brush to work the fluid into tight spaces and agitate the dirt and oil. Blast of with the hose and then re inspect. You ‘ll find most of the muck is washed off, but look for remaining pockets and thick layers that have only been partly removed and attack these with more cleaner and a stiff brush. Use and old toothbrush to get into tight corners. After a second blast, dry the engine down prior to dismantling the necessary parts.
