A high alkaline cleaner above 10 pH is referred to as what type of cleaner?

A high alkaline cleaner with a pH above 10 is known as a degreaser. This type of cleaner is specifically formulated to break down and remove heavy grease, oils, and other stubborn residues that may not be effectively handled by milder cleaning agents. The alkaline nature of these cleaners helps to emulsify grease and fats, allowing them to be washed away easily.

Degreasers are particularly useful in settings like kitchens and industrial environments, where grease accumulation is common. Their high pH contributes to their effectiveness in breaking down complex organic materials, making them ideal for heavy-duty cleaning tasks.

In contrast, a neutral cleaner is balanced at a pH of around 7 and is suitable for general cleaning without harsh reactions. Solvent cleaners typically contain various organic solvents and are used for removing paint or adhesives rather than grease. Heavy-duty cleaners can include a range of pH levels and compositions but can be more generalized compared to the specific formulation of a degreaser. Thus, the unique high alkaline characteristic of degreasers accurately identifies them as the correct answer.
