Improved cleaner-drier compositions completely free of environmentally objectionable chlorinated solvents are provided which include a combination of diacetone alcohol and a terpene fraction such as d-limonene alone or in combination with other terpenes. The diacetone alcohol/-terpene fraction combination should comprise at least about 80% by weight of the overall composition, and the ration of diacetone alcohol to the terpene fraction should be from about 0.4-1.9. The most preferred composition is a 60/40 w/w mixture of diacetone alcohol and d-limonene.
