Abstract

Cationic polymers comprising at least 40 mole percent monomer units of the formula (I): ##STR1## wherein n is 2 to 4, R.sup.1 is hydrogen or methyl, and R.sup.2, R.sup.3 and R.sup.4 independently are hydrogen, C.sub.1-4 alkyl or C.sub.1-4 alkenyl, and X.sup.- is an anion selected from the group consisting of halide anions and monoalkyl anions of sulfuric acid semiester are used as soil-release compounds in hard surface cleaners.
