Cleaning My Rx400H Dusty Engine - All Those Electrics - Anyone Tried I

[Beejay]

I am sure there might be expensive sparks if I steam cleaned it so any hints???

[Duncan Roberts]

Leave it?

I am far from sure that there is any gain if it is merely "dusty". An oil spill might be different but otherwise just leave well alone, few will ever see it.

Well I have a can of Plexus spray - light aircraft windscreen/interior cleaner- and that has done the trick.

I was going to suggest to stay away from water and maybe use compressed air...

Another thing occurred to me was that I have driven through some mighty wet weather over the last 6 months and the under bonnet area was quite wet at times as a result but nothing untoward happened however having chatted to my Lexus man, Steve, who tells me that his Lexus mechs will not clean the engine except a dust off with a high pressure air line I will leave well alone in future....

[ColinBarber]

Toyota/Lexus normally use good electrical connectors which don't allow water in and as you say the engine bay will get wet from normal driving. I would avoid high pressure or steam, brush on an engine cleaner and then just use low pressure to wash off.

Just don't use any sprays if you're worried, I always used to give the engine bay a quick wipe round with an oily rag, or a rag with wd40 sprayed on it.

This gives a more natural look than the shiny sprays, whilst getting rid of the dust.

Thanks for the feedback guys. Although my Plexus aircraft windscreen/plastic interior cleaner is expensive it does a really good job and doesn't attract dust the way WD-40 does and it isn't

a shiny [car dealer engine glaze :-(] finish. :)

Sorry Beejay, I hadn't noticed the Plexus post was yours, and that you'd already sorted your problem.

Agreed about shiny finish underbonnet, always makes me suspicious on a car for sale.
