CLEANING AND POLISHING. 



To Clean Copper or Brass. The next time you think you have 

 done with a lemon just dip it in salt and rub your copper kettle with it. 

 You will be surprised to find what a brilliant surface you will obtain if

 chains treated in this way will look equally as well as when new.
