Most people operate with the general understanding that they need to get their car washed regularly in order to keep the exterior looking nice. Not only that, but regular car washes help maintain your car's paint job. Now, if the outside of your car looks great, so should the inside. As much as it may look brand new, a dirty engine can make your car run like an antique. Never fear! You can actually clean your own car's engine, as long as you don't mind getting a little dirty. It really isn't as difficult as it may seem... Vinaudit
You can't just jump in and hose down your engine. That could be quite dangerous, in fact (think exposed wires). First, you will need to clear out as much of the debris as possible. Thing like leaves and twigs can get stuck in the grill, hood (especially around the seams), and vents. An air compressor is ideal to use as it will just blow away the debris, but it's not something in most people's garages. No air compressor? No worries! A small brush will do.
