To Prevent Torch Lights from Smoking

In the shop or factory oil torches are sometimes used and much trouble is experienced by the excessive smoking of the flame. This occurs because too much carbon remains unburned, and can be remedied by first soaking the wick in a weak solution of acetic acid. A 5-per-cent solution can be purchased for a few cents at any drug store and will soak a great number of wicks. The acid is not poisonous unless taken internally.
