DETERGENTS, additives and special products for cleaning laundry fill several metres of shelves in supermarkets. This comes on top of the wide variety of liquids, powders, gels and pastes for removing stains, not to mention the sheer endless choice of fabric softeners. Do we really need them all?

No, is the clear answer of the experts. Most special products are unnecessary, they say. You only need three types of detergent for fresh and clean laundry, according to a German consumer advice centre: a heavy-duty detergent for whites, a colour detergent for coloured fabrics and a delicate detergent for wool and delicates.
