Fifty parts of rectified alcohol; 1 part of sulphuric acid; 1 part of nitric acid. Plunge the piece in the bath for 10 to 15 seconds, rinse it off in cold water, and dip it next into rectified alcohol. Dry with a fine linen rag or with sawdust.
Stearine oil......... 1 part
Ammonia water..... 25 parts
Benzine............ 50 parts
Alcohol............ 75 parts
Rub up the stearine with the ammonia, add the benzine and then the alcohol, and agitate until homogeneous. Put in wide-mouthed vessels and close care-fully.
Dissolve in a quart of soft water an ounce or an ounce and a half of washing soda, using an old half-gallon tomato can. Into this put the burner after removing the wick, set it on the stove, and let it boil strongly for 5 or 6 minutes, then take out, rinse under the tap, and dry.
Every particle of carbonaceous matter will thus be got rid of, and the burner be as clean and serviceable as new. This ought to be done at least every month, but the light would be better if it were done every 2 weeks.
Acetic acid......... 2 parts
Sulphuric acid...... 2 parts
Oxalic acid......... 1 part
Jewelers' rouge....... 2 parts
Distilled water...... 200 parts
Mix the acids and water and stir in the rouge, after first rubbing it up with a portion of the liquid. With a clean cloth, wet with this mixture, go well over the article. Rinse off with hot water and dry.
Make a thin paste of levigated (not precipitated) chalk and sodium hyposulphite, in equal parts, rubbed up in distilled water. Apply this paste to the surface, rubbing well with a soft brush. Rinse in clear water and dry in sawdust. Some authorities advise the cleaner to let the paste dry on the ware, and then to rub off and rinse with hot water.
