The blooming type, hard surface cleaning concentrate compositions according to the invention comprise the following constituents: 0.1-10% wt. of a terpene containing solvent which desirably includes both pine oil and d-limonene; 0.1-12% wt. of at least one organic solvent other than a terpene containing solvent constituent; 0.1-20% wt. of a nonionic surfactant system which includes both at least one non-ionic surfactant constituent which desirably includes at least one nonionic surfactant having an HLB of greater than or equal to 10, and at least one nonionic surfactant based on a C8-C18 primary alcohol ethoxylate which exhibits a cloud point of about 20 DEG C. or less in water; a bloom enhancing effective amount at least one amphoteric surfactant selected from alkylampho(mono)- and (di)-acetates, as well as alkylampho(mono)- and (di)-propionates, and aminopropionates; and the balance, to 100% wt. of water. According to certain especially preferred embodiments, the concentrate compositions may be characterized in that when the concentrate compositions are diluted at a ratio of 1 part to 64 parts water at 20 DEG C. or 40 DEG C. the resultant mixture exhibits a light transmittance loss of at least 50%. The concentrate compositions may comprise from 0-20% of further optional additives, including antimicrobially active constituent which provide a germicidal characteristic to the concentrate compositions, which antimicrobially active constituent excludes constituents based on quaternary ammonium compounds. The concentrate compositions provide good blooming characteristics when diluted in water to form cleaning compositions therefrom.
