I don't agree with pressure washing under the bonnet, it's to aggressive & will work its way into places you don't want water, a hosepipe is much less likely to cause problems under the bonnet imho :thumbsup:

I used Gunk engine degreaser (spray version), let it work for a good 5-10min, rinsed it with a pressure washer from a distance (so low pressure was applied), turned the engine on to dry it all out. Sprayed Aerospace 303 protectant and wiped it all immediately.

If sellers did that before they sold the car, they would make it much more attractive.

i think this has come up before as i seem to remember expressing a preference for an 'honest' dirty engine bay when i bought my zed due to seeing what had been tw@tted about with and what hadn't.
The patina on mine looked original and probably evolved from when the car was rolled off the production line. It was pretty in-ground and mucky apart from the engine oil filler cap and oil filter cap - confirming it's recent oil change. I just hope it wasn't it's ONLY oil change :o
Everything else looked 'un-touched' and tbh, that was a relief.
Spic and span now however!

I also use rubber gloves over any sensitive electrical bits to keep the water out

Looks good, Gustavo - if it helps, you can actually leave 303 to dry and solely need to mop up drips/runs if you over use it. This way of working will provide a more uniform finish.
