When we talk about pH, we're referring to the measure of how acidic or alkaline a substance is. A pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline. Oven cleaners have a high pH because they contain strong bases like sodium hydroxide or potassium hydroxide, which help break down tough grease and grime.
These powerful chemicals are the reason oven cleaners can tackle even the toughest messes in your oven. But, be careful, because they can also be hazardous if not used properly! Always wear gloves, work in a well-ventilated area, and follow the instructions to avoid any ouch moments.
