Abstract
A cleaning composition comprising: (i) a buffering system comprising a strong base and an organic acid; (ii) an alkanolamine; (iii) at least one surfactant chosen from a zwitterionic surfactant, a non-ionic surfactant, an ionic surfactant and mixtures thereof; and (iv) an organic solvent chosen from lower alkanols, glycol ethers and diethers, and mixtures thereof; wherein the pH of the composition is about 9 to about 13. These alkaline cleaning compositions are useful to remove burnt-on and/or baked-on soil deposits and grease.
