What is the first step to prevent scratching when cleaning a transparent plastic surface?

Flushing the surface with clean water is an effective first step to prevent scratching when cleaning a transparent plastic surface. This action helps to remove any loose dirt, dust, or debris that may be on the surface. When these particles remain on the surface during the cleaning process and are wiped away, they can create scratches, as they can act like abrasives. By thoroughly rinsing the surface, you minimize the risk of scratching caused by these particles.

In contrast, using a dry cloth without first rinsing the surface can inadvertently scrub dirt into the plastic, leading to scratches. A metal scrubber is never advisable for any kind of plastic surface as it will cause significant damage and deep scratches. Applying a cleaning solution directly onto the surface without prior rinsing could also lead to scratching, as any dirt that is trapped under the cleaning cloth can scratch the surface during the cleaning process. Thus, flushing the surface with clean water is a crucial preventive step.
