Hard surface cleaning and polishing compositions

A solvent-based liquid cleaning and polishing composition, suitable for use on hard surfaces, which comprises

• a solvent mixture in which a major portion is constituted by a glycol ether and a minor portion is constituted by a combination of a lower aliphatic alcohol, a hydrocarbon solvent, and water;
• an organic polysiloxane soluble in said solvent mixture, dissolved therein in an amount of about 0.1 to about 7 percent by weight of the composition, and having the repeating group ##STR2## wherein n is an integer having a value greater than 1, R.sup.1 is an alkyl radical containing 1 to 7 carbon atoms, inclusive, R.sup.2 is a member of the group consisting of hydrogen, an alkyl radical containing 1 to 7 carbon atoms, inclusive, and phenyl;
• a silane having the formula
• `R.sup.3 --Si(OR.sup.4).sub.3
• wherein R.sup.3 is selected from the group consisting of an alkyl radical containing 1 to 3 carbon atoms, inclusive, and phenyl, and R.sup.4 is an alkyl radical containing 1 to 2 carbon atoms, inclusive, dissolved in said solvent mixture in an amount in the range of about 0.1 to about 5 percent by weight of the composition;
• and a polycarboxylic chelating acid having a first pK value in the range of about 1 to about 3.5 dissolved in said solvent mixture in an amount in the range of about 0.5 to about 5 percent by weight of the composition.
