Now comes the most crucial step, which is cleaning the grease & grime from your engine. To do this, you will need the aid of a degreaser spray. There are many degreaser sprays available in the market, but we recommend WD-40 Specialist Fast Acting Degreaser. It is a fast, solvent-based degreaser; that effectively removes grease and grime from your engine without leaving a residue. When applying the degreaser spray, make sure that you avoid getting it onto the painted components, for it could clear the paint from the surface of your car. Also, always follow your manufacturer’s guidelines before using any products on the engine.
As a rule of thumb, let the product sit on the surface of your engine for about 3-5 minutes. The dirtier the engine, the more time it will need to be soaked into WD-40 magic. Although WD-40 Fast Acting Degrease is a strong chemical, it will not require a lot of scrubbing from your side. But you can use a bristled brush to get the grime off. We recommend wearing eye protection before going through the job.
Now rinse the engine with a hose. Make sure that you avoid pressure cleaners and use a simple garden hose to rinse everything.
Looking after your engine will help it last longer and function smoothly as well.
