I have just cleared out my tuppaware cupboard and matched the boxes with their lids. I have numbered every lid and bottom that matches (lid 4 with box 4 etc) with a sharpie. This does not come off in the dishwasher! Bloody marvellous!!
Anyone got advice on how to get limescale water marks off a shower door? I have tried washing with vinegar, limescale remover, cif and a scourer etc. It is still cloudy.
