Step-by-step explanation:
The topic of this question is cooking, specifically canola oil maintenance in potato fryers. Canola oil is a popular choice for frying due to its high smoke point and neutral flavor. To maintain canola oil in potato fryers, it is important to filter the oil regularly to remove food particles and debris.
