CLEANING PRODUCTS:GLASS CLEANERS

GLASS CLEANERS

Glass cleaners are primarily liquids formulated to clean smooth glass-based areas such as windowpanes and mirrors. They loosen and dissolve oily soils located on glass, provide a shiny surface, and usually evaporate and dry quickly without leaving a streaking residue. One of the more common glass cleaner formulations contains isopropyl alcohol (CH3CH2CH2OH or CH3CHOHCH3) diluted with water. In some cases, ammonia (NH3) or vinegar (acetic acid; CH3COOH) is added for increased cleaning effi- ciency. Both ammonia and vinegar cut through greasy films, but alkaline ammonia vapors are highly irritating to the throat and entire respiratory system; thus, ammonia-based products should never be used for cleaning in a closed space. Ammonia-based glass cleaners do not leave a streaking residue, as both the ammonia and the water evaporate soon after application.
