Many Military units use only Plexus.
Procedure:
1) Wipe canopy, vertical motions only, (with no pressure at all) with only a clean microfiber towel. This removes settled dust that will scratch when cleaning.
2) Spray Plexus on front. Let sit one minute to soften bugs.
3) Wipe canopy in vertical motions only, (with light to medium pressure) removing the Plexus and bugs. Every time, use Clean Lint free towel or microfiber rag.
Note:
Vertical motions only, with canopy cleaning, will ensure you don't acquire the common circular micro scratches that can blind you when looking through it near the sun. This process will preserve your finish on your canopy. Canopy is expensive and a pain to replace.
