What is the recommended cleaning method for plastic guards?

Using an alcohol-based solvent is recommended for cleaning plastic guards because it effectively removes dirt, grease, and other contaminants without damaging the plastic. Alcohol evaporates quickly, thereby reducing the risk of moisture damage, and it generally leaves surfaces streak-free. This method ensures that the integrity and transparency of the plastic guard are maintained, which is essential for visibility and proper functioning.

In contrast, a dry cloth may not effectively remove all contaminants, especially sticky residues. Soaking in cold water can lead to prolonged exposure to moisture, which might not be effective for thorough cleaning and could introduce other issues like mold over time. Using abrasives can scratch or dull the surface of the plastic, leading to permanent damage and reducing its effectiveness. Thus, the use of an alcohol-based solvent strikes the right balance between cleanliness and preservation of the material.
