Copper Pans—to Clean.
Mrs. Hart says use vegetable grease-proof parchment paper. First wash the copper pans well inside and out with soda in warm water.
Take a teaspoonful of a mixture of silver sand and soft soap, mixed in a proportion of ½ lb. sand to 1 oz. soft soap.
This is for tinned inside of coppers—scrub round on a small piece of the paper—when cleaned rinse it well. The outside of the pans must be cleaned with vinegar and silver sand, rinse them again and dry and air them well.
If without paper use your hand, but paper is cleaner and safer (a girl's nail sometimes scratches off the lining and the copper poisons the hand).
