Two ways to reduce the time needed to clean inaccessible areas are to prevent contamination and to __________.

• A. Increase area size
• B. Make the areas more accessible
• C. Increase cleaning chemicals
• D. Reduce ventilation

Answer: (B)

Hard-to-reach spots take longer to clean, so two effective ways to cut the time are preventing contamination and making those areas easier to reach. When you prevent contaminants from getting into those spaces in the first place, there’s less grime to remove later. The other key move is improving accessibility: if panels, openings, and clearances are designed so cleaners can reach corners and crevices quickly, cleaning becomes faster and more efficient.

The other options don’t directly reduce the time spent cleaning inaccessible areas. Increasing the area to be cleaned adds more surface that needs work; relying on more cleaning chemicals can help with effectiveness but doesn’t inherently shorten the time spent, and changing ventilation in this context doesn’t address the time spent cleansing hard-to-reach places.
