434. Medicine Stains may be removed from silver spoons by rubbing them with a rag dipped in sulphuric acid, and washing it off with soapsuds. 435. To Extract Grease Spots from Books or Paper. Gently warm the greased or spotted part of the book or paper, and then press upon it pieces of blotting-paper, one after another, so as to absorb as much of the grease as possible. Have ready some fine clear essential oil of turpentine heated almost to a boiling state, warm the greased leaf a little, and then, with a soft clean brush, apply the heated turpentine to both sides of the spotted part. By repeating this application, the grease will be extracted. Lastly, with another brush dipped in rectified spirit of wine, go over the place, and the grease will no longer appear, neither will the paper be discoloured. 436. Stains and Marks from Books. A solution of oxalic acid, citric acid, or tartaric acid, is attended with the least risk, and may be applied to paper and prints without fear of damage. These acids, which take out writing ink, and do not touch the printing, can be used for restoring books where the margins have been written upon, without injuring the text. 437.
