It's safe to serve food on Real English Ironstone china, but hot foods can cause cracks. Before serving hot food, warm the dishes for 10 to 15 minutes in an oven set to 175 degrees Fahrenheit. Don't serve any foods that are hotter than 200 degrees Fahrenheit on ironstone china. If possible, avoid using metal flatware with this china, since metal flatware might leave scratches and marks.
Remove food from Real English Ironstone china with a soft sponge, rubber spatula or warm water. Don't use rough sponges, such as metal sponges, or strong detergents, since these cleaners may scratch or strip the glazing on the china. To ensure that your ironstone dishes remain in good condition, wash them by hand and avoid using the dishwasher. When washing dishes, line the bottom of the sink with towels or rubber mats to prevent the dishes from breaking or cracking if they're accidentally dropped.
To remove stuck-on dirt or food from Real English Ironstone china, use baking soda, warm water and a soft sponge. The baking soda scrubs off the dirt without scratching the china's surface. To remove stains, such as discoloration, place pieces in an airtight container containing 3 percent hydrogen peroxide for a few days. After removing the china from the container, place the pieces in direct sunlight until the ammonia vaporizes. Wash the dishes before placing them on display or serving food.
Real English Ironstone dishes may get scratched if they're stacked on top of one another. Instead, place soft towels, paper plates or cloths between dishes. Whenever possible, keep your china in a room or cupboard that's heated to a moderate temperature. Extreme cold or heat might cause the dishes to crack.
