We went away on holiday for 3 weeks, and though I cleaned out the fridge, when we came back there was mold on the shelves on little bits of food which I had missed AND more disgustingly an orangey sludge on the back drip trough?? which has a little hole in it and goes inside the back of the fridge. (I know it's not clear but I'm really not sure what it is or how to describe it. ) Anyhow, cleaned out the fridge before putting stuff in it with hot water and bleach mix. BUT the sludge is back and my food seems to be spoiling rather quickly...
Is my fridge ruined? It's only 3years old
