I agree. The clumps of white stuff surfacing from my U bend cant be fat based. As a vegetarian hardly any solid fats in my diet. Although it looks and feels greasy, and floats, I kept a couple of pieces which have now dried out to a white crumbly lump which very much resembles the contents of the dishwasher sachets. However unintuitive it seems.
