Abstract: A non-hazardous, non-flammable, biodegradable composition for use in removal of paraffin accumulations in oilfield equipment may contain limonene, a glycol ether an ethoxylate(alcohol surfactant, an aliphatic alcohol having 1 to 4 carbon atoms or mixtures thereof, a non-hazardous and biodegradable organic acid, and, sufficient water as a carrier and comprising such a major weight component of the composition as to virtually eliminate a measurable flashpoint therefor. Preferably the aliphatic alcohol is one or methanol, ethanol, or admixtures thereof. Preferably the organic acid is one of acetic acid, citric acid, or formic acid.
