Abstract
An outside window cleaner comprising mixtures of one or more polyvinyl alcohols with water, or preferably, polyvinyl alcohol, a cationic polymer, such as trimethylol melamine, and water, alters or modifies window or other hard surfaces such that water drains off in uniform sheets, leaving virtually no residue or spots caused from the deposition of dirt, cleaning compositions or a combination of the two. In a further embodiment, a selected cationic or nonionic surfactant is added to the formula of this invention to improve detergency while retaining the uniform drainage advantage in rinsing.
Claims7
A composition for cleaning and altering hard surfaces such that water used to rinse said hard surface drains off in uniform sheets without leaving significant residue or spotting after rinsing comprising:
- (a) No more than about 10% of at least one polyvinyl alcohol having average molecular weight of about 22,000 to 400,000;
- (b) At least 80.0% water;
- (c) About 0.0001 to 10.0% of a cationic or nonionic surfactant to add detergency to the composition without deleteriously affecting the sheeting action of rinse water from said hard surface;
- and
- (d) A polymer containing at least one primary or secondary amino functional group, said polymer being selected from the group consisting essentially of trimethylol melamine, dimethyl ethylene urea, triazone resins and dialdehydes, wherein said polymer of (d) and said polyvinyl alcohol of (a) are present in a ratio of about 15:1 to 1:15.
A method of cleaning hard surfaces without leaving significant residue or spotting after rinsing, comprising:
- applying to a hard surface a cleaning composition which comprises:
- (a) No more than about 10% of at least one polyvinyl alcohol having average molecular weight of about 22,000 to 400,000;
- (b) at least 80.0% water;
- and
- (c) a polymer containing at least one primary or secondary amine functional group, said polymer being selected from the group consisting essentially of trimethylol-melamine, dimethyl ethylene urea, triazone resins and dialdehydes, wherein said polyer of (c) and said polyvinyl alcohol of (a) are present in a ratio of about 15:1 to 1:15.
