Steam Cleaning

Evening All,

Just a quick one, got my engine filthy at the weekend,

Got one of them hand car wash things up my road, they were advertising engine steam clean for a tenner, so i thought LOVELY

So they started to do it, but im not too sure if it was actually a proper steam clean, it was more like a pressure washer on the misty setting,

Just wondering, should they have covered things up? and should engine be on or off?

because they left engine running, didnt cover anything up, just sprayed some like degreaser stuff over it, then washed it

Ok its come up very clean, looks good but i dont know if they have done it right,

on the way home she was making a high pitched screaling, which i would have thought is the belts from being wet or something

Also, when i got home i looked under the bonnet, found a sticker saying re wax after steam clean,

what wax should i use and where do i put it?

Could any one shed some light on steam cleaning for it, is it safe to do it? covering bits up etc,

on the way home it ran lovely, no mis fire etc too

Steam cleaning generally isn't worth the hassle, nor power washing an engine, as you realise it can de-grease parts which need greasing, and can cause death to electronic parts. Best to let mud dry and fall off by itself, or use a garden hose judiciously.
