A carton of milk leaked on it a week ago. I’ve scrubbed an sluiced the rear compartment as best I can with every household cleaning material I could find. Hoping the niff will go away.
Cleaned the floor in situ. It looks like you can get replacements on EBay, but removal looks complicated for someone of my limited abilities on Christmas Eve. The rotating mechanism is under a piece of plastic trim on either side - the assembly includes a D luggage hook - the middle of the D comes away to reveal a Torx bolt head and I think if you unscrewed that, the trim would come away, or become a step closer, anyway. Then there was a cross head screw at the centre of the pivot mechanism. I think removing that would release the floor.
