When cleaning built-in appliances, which areas should be focused on?

When cleaning built-in appliances, focusing on mounting cavities and sub-surface areas is crucial for several reasons. Mounting cavities are often the places where dirt, debris, and grime accumulate due to the appliance's connection to cabinetry or walls. These areas may be overlooked during surface cleaning, yet they can harbor allergens and cause unpleasant odors if not maintained.

Sub-surface areas refer to parts that are not easily visible or accessible but can still attract dirt and can contribute to the appliance's overall hygiene and performance. By ensuring these areas are properly cleaned, you help maintain the appliance's efficiency, prolong its lifespan, and improve indoor air quality.

Understanding the specific areas that need attention during the cleaning process is essential to achieve a thorough job and ensure customer satisfaction in the carpet cleaning industry. Other options may emphasize components that could be less significant in terms of functionality or cleanliness, making them less relevant in this context.
