Chemical product for rapid removal of food burned on to the surfaces of cooktops

Abstract

The chemical formulations use chemicals that are use or have been used for other cleaning purposes such as rust stains, but not for glass or glass-ceramic cooktop surfaces. In an embodiment for cleaning glass or glass-ceramic surfaces, percentages of active ingredients, such as either hydrofluoric acid (HF) or ammonium bifluoride (NH4HF2), can be formulated at an about an order lower in concentration by weight than those formulations originally used for removing rust stains (e.g. using the same chemicals for removing rust stains but with a lower concentration for different uses, wherein a different use includes removal of food burned onto cooktops). Additionally, even at the lower concentrations of the active ingredient the physical effort involved and the time for cleaning/removal are much less than with commercially available cleaning products.
