Pipes oxidation

Noticed this last night, I appear to have oxidation on the pipes. Am I correct in thinking its the coolant?

Air-con refil/charging pipe. There's another by the brake fluid reservoir. Couldn't see oxidation in your pics but not noticed any on mine. 2011 SD4 HSE Auto

I have this. It appears to be a white oxide type powder but also some rust. Looks like it's on the bulkhead. Warranty job for me. Dealer sorting. Only thing I can think is the acoustic blanket screw hole is rusting. Too cramped to get in there * GONE. GS TD4 Manual MY2013.

White oxide type powder will form on alloy and some plated components due to salt spray picked up during the winter months on the road, especially the underside and under bonnet area of the car, not a lot you can do about it other than dont go on the salted roads or spray the items with an anti corrosive spray like a waxoyl, that though can look scruffy after a while as that picks up all the dust, but at least the component under it is still as good as new and it can be cleaned off and recoated.

The salt ruins all plated annodised items or bare alloy castings on a car once it gets onto them. Rolling Eyes

salt ruins to look of new galvanised trailers too, used galvanised trailers not so bad, so buy anything galvanised in early summer , it should have weathered a bit and become salt proof before winter At work

That's why you shouldn't polish off the grey patina on galvanised steel. The ZnO (zinc oxide) that forms on the surface over time is more resistant to corrosion than the fresh surface. So all you do when you polish it off and make it nice and shiny again is remove some of the anti corrosion layer. Eventually you run out of zinc and the protected surface is then free to rust in the normal way.

Probably why my old battered dustbin is still rust free condition then. Thumbs Up

The only polish up that gets is when next doors cat jumps on it in the night Rolling Eyes
