As I disconnected my headlamp washers ages ago I've decided to get rid of them altogether and fill the holes. The inserts on both bumpers have some scuffs so I'm going to tidy the lot up.
I had a look underneath this afternoon but couldn't find room to get any sort of meaningful weapon on the big nut that appears to hold them in place. I don't particularly want to pull the bumper off so my mind went straight to bodge mode.
The obvious solution seems to be to remove them from the top by breaking them up into tiny little pieces. However, this will be much more difficult if, under the plastic, there is any sort of metal structure. The question then, is whether the washer jet assembly is 100% plastic or part metal.
