THE NATURAL OPTION:
Below are ingredients for a natural solution commonly used to address tough-to-remove kitchen grease:
Combine one part lemon juice and one part vinegar. Add two parts baking soda to the mixture and stir to make a paste. Spread the paste over the grout and tile. Make sure it has good contact with the hardest hit grease areas. A soda glass backsplash may get filmy during this process but won’t be harmed by the gentle grease remover. Simply buff out the glass until its former shine returns.
