Some tips below from our butchers on keeping your knives.
Stainless Steel Blades:
Hand wash and dry knives.
Do not put knives in dishwasher.
Carbon Steel Blades:
Hand wash and dry after each use.
Do not put in dishwasher.
Put away dry to prevent rust.
As you use your carbon steel knives they will develop a pearlescent patina that will help protect it from rust and stains.
To remove any blade stains, lightly scrub with steel wool and household cleanser, such as Bar Keepers Friend.
