Thanks a bunch - Lards!
Because of this, I had to get the fridge out and inspect the waste/condensate tray at the back (behind the panel)!
Full of nasties, all different colours and shapes, and needed a severe scrub-out and a wire pull-through to clear the nozzle...
And now, to cap it all, we have a mouse delivering 'normals' in a cupboard nearby, and lots of pans and pots are affected! Where the lttle blighter got in, I don't know, but it won't like the little sachet of 'sweeties' it has laying in wait!
You really have started something here, and maybe deserve a medal or something!
