Vintage Corning Ware Spice of Life Le Tea, Metal Lid J111

Whilst this teapot remains in good overall condition, it has clearly been previously loved and enjoyed. We have given it cursory cleaning with baking soda, but stronger measures may be required. The only 'damage' we see is what looks like rusting to the inner rim of the lid, but again, strongly suspect that is simply tea stains. Handle is strongly attached,
