My kitchen sink really stinks- kind of musty. I don't use it very often because we use the dishwasher but it really smells. I have tried come kitchen fresh granules, bleach and bicarb of soda but nothing seems to help. When we come down in the morning when the door has been closed all night it nearly knocks me out . Any advice? It is a very short waste pipe (about 1/2 a metre before it goes outside) and I'm positive there's nothing blocking it. It doesn't get any worse when the washing machine or dishwasher are on so I think they're OK...
Any Anthea tips would be much appreciated!
