Scirocco Register

For those of you who have seem my car its very clean..

So to date i have spent a fair bit of time under the bonnet cleaning but i dont want to go too far. I am not removing any of the waxoil - its meant to be there and if its not on view then i am not removing bits of trim to get at it but if you can see i then i want it clean
However what i am concerned about are the parts that look like they are meant to have grease on them to keep them lubricated.
I clean under the bonnet with wd40 and a rag so i hope i am not going to do any damage but ..
advice would be appreciated as what to leave well alone

leave nothing alone pal just dive right in, i typically spend on average a good 48 hours to fully detail my cars every month, and thats cleaning,claying,polishing,waxing, hoovering replacing any old nuts and bolts, steam cleaning you name it i clean it.
