I arrived home from driving the kids to school this morning to find my kitchen sink blocked up cause DD2 poured the fat from the sausages last night down the drain and it has set. (I didn;t know she had done this as she proudly cooked all by herself!! I did wonder this morning where the fat had gone, now I know)
Anyway I poured some bi carb and vinegar down there with a bit of boiling water but no luck, what do I do???????????????
