Autobrite Jaffa Clean
It’s a strong degreaser for engine bays and door shuts BUT it also has a ‘finishing agent’, in that it leaves a shiny non greasy protected finish behind.
I don’t like using hoses in engine bays unless I really can’t avoid it.
Spray on the engine, agitate with a detailing brush and wipe off with some microfibres.
On door shuts, spray on, let dwell and pressure wash off. For caked on door hinge grease, spray on, let dwell, agitate with a brush and then pressure wash off.
It’s only a 500ml bottle but it dilutes 5:1 making it much more economical.
