Query: Le Creuset Enameled Cast Iron Cleaner

This product did not remove month old stain on my Le Creuset Dutch oven. Also, it did not bring back shine to the enamel. It recommends wearing rubber gloves while using this product. The label does not specify that this product is biodegradable. Le Crueset recommends removing stains from enamel by boiling 1 part Tide or Gain and 3 parts water for 10 minutes in the enameled container. Let cool and wash with dish wash soap. Dry the container and then rub with white vinegar to renew shine.
