A dirty engine bay on a perfectly detailed car just doesn’t look right and while some people may think this is a dangerous or risky task – it isn’t. Many owners don’t detail their engines because they’re scared of damaging something, but modern cars and their bays are generally pretty well protected.
Now before we start it is important to note that the engine should never be hot, always make sure the vehicle hasn’t recently been driven. Once the engine has cooled, place a plastic bag over any exposed electrical parts such as alternator or batteries – also your air intake if it is exposed. Everything covered up? Great, let’s get right into it.
Step 1: Washing
Just like we do with the paintwork, apply a pre-wash to the engine bay such as Citrus Power from Auto Finesse or an All Purpose Cleaner (APC). Allow this to dwell and rinse away allowing the bulk of grime to be washed away.
Apply more of your cleaning product and agitate with a soft bristle brush, remember to get the underside of the bonnet here as well. Work the product into the dirtiest areas and once everything has been cleaned give the bay a rinse once more and dry with a microfibre towel.
Step 2: Dressing
A Dressing will help keep the rubber components under the bonnet protected and aid them from drying out. Apply a product such as Auto Finesse Dressle or Satin to the rubber, plastic and vinyl, allow to cure and wipe off with a microfibre towel. – You guessed it, never use this towel on the paintwork either.
Top tip here: I usually go to town on the engine bay with the dressing, let it sit for 5 to 10 minutes then go round the engine bay with a older towel and get off any streaks etc.
There you have it! A perfectly detailed engine bay! I usually do this twice a year, once In the winter and again right before summer.
