All Christofle flatware can be put in the dishwasher.
If it isn’t possible to wash silverware immediately after use, wipe off any remaining food with paper towels and then rinse in hot water. This will stop prolonged contact with acidic substances which can damage silver.
All Christofle picture frames are varnished and do not require any special care. Do not use Christofle or household cleaning products, which could damage the finish. A soft, dry cloth is all that is needed to remove dust from varnished products.
For items of silver and wood, do not let the cleaning products come into contact with the wood.
Use a soft sponge and soapy water. Never use a corrosive or abrasive product. Never let your silverware come into contact with bleach. Promptly dry with a soft cloth.
