Products we recommend to clean and shine the engine bay.

For Dirtier engine bays use the Autostolz All Purpose Cleaner Cncentrate and a dilution bottle to adjust the strength of your cleaner, 10% is a normal good strength for all purpose cleaner but you can raise this to 20% or 30% for dirty engine bays.  Don't use undiluted.

Take car around electrical items, especially if rinsing off, we recommend covering them.  We don't recommend high pressure water like a water blaster unless very careful as it can push water into electrics and areas you don't want water.

Remember what you rinse off will land under the car so rinse there too or lay something down if very dirty.

To Protect and shine plastic and rubber chemical guys VRP is good, its water based so can run or spot in water but under the hood you are normally ok.  Fireballs Tyre and trim shines last longer and include a high % of SiO2 so last longer.  Solution Finish is for when the trim is very faded, it's a restorer not a trim shine.

The Boar Hair Brush is your most useful for engine bays, the hard chemical resistant brush can be helpful in some carses as its stiffer and more aggressive but normally the boar hair is the best choice, it also can spread out making it easier to get in under pipes and hoses and into corners etc.  The soft short wheel & engine bay brush is also great for the larger surfaces and will speed cleaning those up noticeably.

A strange but useful tip, for gaps around the engine a long wheel barrel brush works really well.  The blue one is what we use but if it really needs a good scrub the brown one will get results faster as it's stiffer.

Cloth wise the rockcar roadie will grab and clean better and will absorb really well.  Colour code black or dark grey so you can tell your cloths apart.  A good cloth makes the job easier and quicker.

For Metal we make our own metal polish KingsOfChrome that we are super proud of, KING will be your best bet here, FAST is a sprayable metal polish less cut higher shine to take it to that next level or if the metal isn't too bad.
