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

A method of cleaning baked and burnt blackened food stain from a glass or ceramic cooktop surface comprising:

• the cooktop includes a burner to burn and bake food onto the glass or ceramic cooktop surface to provide the baked and burnt blackened food stain onto the glass or ceramic cooktop surface;
• providing a non-etching formulation for cleaning the blackened food stain from the ceramic or glass cooktop surface;
• the non-etching formulation comprising 2.5% to 0.5% of hydrofluoric acid (HF);
• wherein applying the non-etching formulation to the blackened food stain on the glass or ceramic cooktop surface, the non-etching formulation provides 100% efficacy in cleaning and removal of the blackened food stain from the glass or ceramic cooktop surface and;
• wherein the glass or ceramic cooktop surface is free of etching after the removal of the blacken food stain.

A method of determining a concentration of hydrofluoric acid (HF) for safe application and lack of etching on a glass or ceramic cooktop surface, and the glass or ceramic cooktop surface having burnt and baked food, and the burnt and baked food provides a blackened stain burnt onto the glass or ceramic cooktop surface comprising the steps of:

• determining that a concentration of 2.5% to 0.5% of hydrofluoric acid (HF) provides for safe application and lack of etching on the glass or ceramic cooktop surface;
• applying a formulation of 2.5% to 0.5% concentration by weight of hydrofluoric acid (HF) onto glass or ceramic cooktop surface and;
• the formulation removes the blackened stain which is burned onto the glass or ceramic cooktop surface, further comprising;
• about 100% efficacy in removal of the blackened stain which is burned onto the glass or ceramic cooktop surface;
• the glass or ceramic cooktop surface is free of etching from the 2.5% to 0.5% concentration by weight of hydrofluoric acid (HF).
