The washer jets on my car are getting a bit weak and feeble, water barely makes it onto the bottom of the screen rather than up onto the bit you look through. Rear washer is OK so I don’t think there’s a problem with the pump. I suspect the jets are clogged and need descaling. I’ve found some YT videos which say you need to remove the black plastic panel at the back of the outside of the bonnet. This looks straightforward in the video, but just thought I’d ask if anyone else has done this, is it as easy as just unbolting on the inside and “popping it off”. Are the clips likely to break, should I get some spares (anyone know what they are)? Thanks in advance.
