When setting out with Engine bay detailing there are some very important things you need to do before the cleaning process begins.

After lifting the bonnet to reveal the engine you need to follow certain steps so that you do not damage any components of the engine.

  1. Designated engine cleaner or diluted multi purpose cleaner.
  2. Detailing brush (soft)
  3. Microfibre cloth
  4. Sponge applicator pad
  5. Engine dressing or protectant
  6. Metal Polish
  7. Wire Wool
  8. Pressure Washer
  9. Cling Film or equivelant

Important! Before starting the engine cleaning process make sure you have positioned the vehicle in a suitable place for dirty oily greasy water to run off, not on your newly concreted drive etc.
