Which of the following is NOT a recommended action while cleaning glass on the JLTV?

Using abrasive cleaners is not a recommended action while cleaning glass on the Joint Light Tactical Vehicle (JLTV) because they can scratch and damage the glass surface. The integrity of the glass is essential for visibility and safety, and abrasive materials can lead to permanent damage that reduces the effectiveness of the glass, causing issues in various environmental conditions.

In contrast, mild detergent, washer fluid, and isopropyl alcohol are beneficial for cleaning glass. Mild detergent effectively removes dirt and grime without harming the surface. Washer fluid is specifically designed for automotive glass cleaning and helps maintain clarity while being safe to use. Similarly, 90% isopropyl alcohol can aid in removing stubborn stains and cleaning the glass while evaporating quickly, thus minimizing the likelihood of streaking. Each of these options ensures that the glass remains clear and functional, enhancing the driver's visibility and safety.
