Thread: is it safe to use degreasers around sensors?

Hi - my crank angle sensor of D2 Td5 is filthy but looks like a bitch to get to...I'm assuming it wouldn't be a problem to just hit it with some spraycan degreaser given that they're just simple points?...the MAF would be a different story. Any other issues with using degreaser under the bonnet (apart from being careful with spraying water around to clean it off...)?

Dunno but I would personally use contact cleaner instead. Just me. As for spray degreaser, it works better if you brush it on with a stiff brush, eg an old dishwashing brush, then you don't need much water pressure to shift it afterwards.
