Important: Safety Warning
This page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.
This page directs the use of hazardous substances — such as benzine, gasoline, lye, or strong acids — for household tasks. These materials are highly flammable, corrosive, or poisonous, and the practices described have caused fires, burns, and poisonings.
This information has been left in for historical purposes but should not be acted upon.
Aromatic Vinegar
- Mix with a spoonful of vinegar, powdered chalk sufficient to destroy its acidity; let it settle; turn off the vinegar from the chalk with care, and dry it. To purify an infected room, put in a few drops of sulphuric acid. The fumes arising from it will purify a room where there has been any infectious disorder. In using it, be very careful not to inhale the fumes, or to soil your garments with the acid. It will corrode whatever it touches.
