1. A method for cleaning a hard surface comprising:
- a) providing an improved cleaning composition, said improved cleaning composition including a cationic biocide, a cationic biocide release agent which promotes release of said cationic biocide from an absorbent material, surfactant, solvent and water, said cationic biocide including a biguanide compound, said cationic biocide including about 0.05-5 weight percent of said cleaning composition, said cationic biocide release agent having an ionic strength in said improved cleaning composition of about 5×
10−
3 mol/l to about 18 mol/l, said cationic biocide release agent including a salt selected from the group consisting of potassium citrate, sodium citrate, magnesium sulphate, sodium chloride, ammonium chloride or mixtures thereof, a majority of said solvent including a compound selected from the group consisting of methanol, ethanol, n-propanol, isopropanol, various positional isomers of butanol, pentanol, hexanol, glycol ether, acetone, PnB, DPnB, Hexyl Cellosolve or mixtures thereof, said water constituting a majority weight percent of said cleaning composition; and
b) contacting said hard surface with said improved cleaning composition to at least partially disinfect, sanitize, or sterilize said surface.
