Methods for treating glassware surfaces using corrosion protection agents.

• A domestic, institutional, industrial, and/or com. method of reducing glassware surface corrosion in an automatic dishwashing appliance comprises the step of contacting a glassware surface with a corrosion protection agent comprising: (a) an effective amt. of a zinc-contg. layered material, said material having a particle size in the range of about 1 nm to about 100 nm and a crystallinity value of from about 0.4 to about 0.8625 FWHM units, at a 200 reflective peak; and (b) optionally, an adjunct ingredient and (c) a dispersant polymer: said contacting being done at a pH greater than 9 to about 14. Methods using corrosion protection agents that form a part of a treatment system and/or are incorporated in a compn. of matter are also provided. [on SciFinder(R)]
