Can anyone help with advice? Pale beige sitting room carpet. The entrance into the room is quite discoloured from not being vacuumed often enough (long story), and there are also particular small marks - brown but I don't know what caused them, though definitely not food or drink, and we don't have pets. Does anyone know a reliable way to make it look decent by tomorrow? The sofa upholstery (light grey) also looks a little grubby where DH lies on it a lot. Thanks very much for any advice.
