Why is it important to use clear water after cleaning the bowl optics?

Using clear water after cleaning the bowl optics is essential to prevent cloudiness and water spotting. When cleaning optics, residues left behind—such as soap, cleaner, or minerals—can lead to a film that compromises clarity. Clear water helps rinse away these residues effectively, ensuring that the optics remain transparent and free from any obstruction that could distort vision or affect performance. This is particularly crucial in contexts where precise measurements or observations are necessary, as any interference can disrupt the accuracy of results.

While other factors like washing off chemicals, enhancing color, or drying faster are important in different contexts, they do not directly address the primary concern of maintaining clarity and preventing spot formation on the optics after the cleaning process. Thus, using clear water specifically targets the need for optimal optical performance.
