Anyone had their engine/bay professionally cleaned?

[wax lyrical]

I have a 13 year old E93 BMW 335i, with a filthy and grimy engine and engine bay. I'd like to get this cleaned properly, but am wary of potential electrical gremlins afterwards due to water ingress.

All advice and opinions welcome! Pros and cons of doing this? I try and look after my car, but the engine lets it down. I know it's hardly ever seen, but you know what I mean...

You can do it yourself if you want, it's not that difficult and you can be careful around anything electrical.

YouTube is your friend.

This is how ChrisFix does it.

I watched a good video over the weekend, it seemed pretty easy to do. https://www.youtube.com/watch?v=XGjvVVbekJM

Not hard to do. Just don't get the end of your jet wash right up to the electrical contacts and you'll be fine. I do mine myself.

I clean my 330i engine bay without a jetwash because I am nervous of it penetrating parts that don't like water.

I use a stiff dishwashing brush, plenty of clean water and generally just give the engine covers and other parts a scrub. Then clean down with progressively cleaner rags, then just dress with some sort of silicone based cleaner. Then a final clean with a microfibre cloth to remove any excess silicone.

Never created a problem and takes about half an hour. It is not a perfect job but certainly looks better than when I start.....
