Best way and what products do you use? Never cleaned under bonnet before but wanting to give both the cars a good clean out. Not sure what I should use though, had a look around the Internet and it's mixed opinions so thought I'd ask what you lot use.

I have covered the electrics on my old mk1.5 etc with tin foil, then sprayed water lightly over it all, then used autoglym engine cleaner/degreaser and then sprayed water again to rinse off.

No ill effects but that is a very
mixed opinion about spraying water in the engine.

I wouldnt do it on my mk2.5 as it has audio cables and all sorts so.. I used loads of microfibre's and quick detailer to clean the whole engine (time consuming) with a detailing brush to get into crevices.

Meguiars tyre shine to dress rubber bits like hoses.
Meguairs trim restorer for all the faded black plastic.

Pack of detailing/toothbrushes worked for getting into places my fingers Couldnt.

Deffo do the underside of the bonnet first, otherwise it'll drip over the engine!

Make sure the engine is cold when you begin to clean. If you use water anywhere then turn the engine on after you have finished to help dry any remaining water.

Your bumper, wings and windshield may get dirty so do it before cleaning the outside of the car!

My mk1.5 stayed clean for around a year, no joke, even when it rained.

My mk2.5 stayed clean for about a month if that before there was spray and water marks and dirt all over it.
Must be a design thing!

Thanks for the guide, yeah I have read of lots of people using damp microfibres, will have to get some cheap tooth brushes as well :)

No worries :) ill try and find my before and after pictures and put them up so you can see what can be achieved!

If you did need something for more stubborn areas, you could try something like quick detailer or the 'waterless soap' stuff i think turtlewax does, as you dont need to rinse either product off after so its all safe.

Be careful on painted parts with the toothbrushes though, especially the rear of the bumper as on my mk2 I scrubbed a little too hard and off came the paint.. I guess its not as thick or laquered under there haha.. Good job it cannot be seen!

Cheers bud! Yeah surprisingly easy to achieve too. Just time consuming and really annoying when theres a bit you cant reach ha! Or in my case the alternator housing was discoloured and there was a crack in the battery cover :/

all i could say is dont use a hose and loads of water get a hand pump pressure sprayer from homebase or something and use a light misting of water

I agree. I used a garden hose with a head attachment that only produced a little mist.

Ahhh nice! Looks excellent mate! You'll probably notice the odd raised eyebrow from garages when they open the bonnet to see a clean engine bay!

Haha more than likely! I bought my golf of my mechanic, he hasn't cleaned under the bonnet though, so il have to get the golf done next. Think he was shocked when I got the carpets and red recaros vac cleaned in it, looked like a new interior lol

Mind if i use the pics you posted above for a thread on engine bay cleaning? Thought I'd throw together a few tips n stuff, maybe make a sticky out of it for the car care and cleaning section!
