How to Clean an Engine Bay

Cleaning the engine bay is one of those areas that is often overlooked when washing your car. Perhaps you only open the bonnet if you really need to or maybe it seems like too big a job to tackle all that built up grease and grime. With just two G3 Pro products – Multicleaner and Super Dressing – we’re going to show you how to detail your engine, taking it back to factory fresh condition.

  1. First up, make sure the engine isn’t hot. Too hot and you’ll bake the cleaners on and acquire watermarks. A little warmth is OK as it can make the oil and grease build-up more compliant for removal.
  2. Cover any key electrical components. Modern cars generally have plastic trim over batteries, coils etc, but on older cars it would be wise to cover sensitive areas such as battery terminals, alternator, distributor and exposed air filters with plastic bags and tape.
  3. If you have a pressure washer, you can use G3 Pro Multicleaner through a snow foam lance. Using this method gives great coverage in seconds, whilst aerating the the solution helping to lift dirt away from the surfaces of the engine bay.
  4. If you don’t have a pressure washer, you can simply spray G3 Pro Multicleaner direct from the bottle – either neat or diluted 1:3.
  5. Allow G3 Pro Multicleaner to dwell for a few minutes before agitating with a brush to get into the tight areas around bolts, trim etc.
  6. Rinse away the dirt using a low pressure.
  7. Once dry, apply G3 Pro Super Dressing, wiping on and buffing off with a cloth, to protect plastic and rubber trims for a new look finish.
