I use the HD quick detail spray on my windshield (Harley Gloss). Seems to roll the water off pretty good.

 

Another for Plexus. It's made for plastic windshields.

 

This mixture is from a company that makes custom windshields. Not all plastics are affected by ammonia and a good quality windshield wont be either.


We make our own cleaning fluid. When you buy a windshield from us, we give you a small spray bottle of cleaning fluid and a micro-fiber cleaning towel. Here's our "secret" washing fluid recipe, the result of testing about 25 different formulas:
Makes 1 quart = 1 liter windshield washing fluid
• 1/2 cup = 100ml ammonia (double this if you have a lot of bugs)
• 2 cups = 400ml isopropyl (rubbing) alcohol
• 1.5 tsp = 8ml car wash detergent (don't substitute dish soap or laundry detergent)
• 2 cups = 500ml water
We recommend using only micro-fiber cleaning towels on your windshield.

 

Ive always heard not to use rainx on plexiglass but I dont remember the reason, Iwill use a spray wax/detailer kind of scrub the bugs with fingernail (key is to have a liquid film on w/s so you dont scratch it) then dry with micro fiber and respray a finish coat to shine been doing it for 15 years and never had an issue.

 

yes, agreed with the previous posters, windex corrupts the surface and will ruin a windshield. it's the ammonia. glass plus has no ammonia. and the hydrogen peroxide works too.

 

Years and years of Hydrogen Peroxide, and never a bad issue. Once clean from bugs, Plexus to finish her off. Guarantee NO PROBLEMS!!

“Plain water and a microfiber cloth. Dry with a microfiber cloth!”
Has my vote. H20 is all I’ve ever needed.

 

Hot water and vinegar about (30%) in a spray bottle let soak for 10-15 mins then wipe with clean microfiber cloth, finish with Pledge....

 

Novus #1 Its made for the application, polishes the shield so watter beads and rolls right off, and bugs come off easy.

 

HondaLine All Purpose Cleaner. I use it on every part of my Ultra, including the windshield. The only water that ever gets on my ride is rain. My Harley dealer actually sells a cleaner that he admitted is HondaLine product. Great stuff.
