An anti-fog, anti-static formula that seals pores in the plastic.

Unlike many sprays that just clean the surface and leave it exposed, the Camco formula actually seals microscopic pores in the plastic to create a protective barrier. This stops browning and hardening, which is a common issue with isinglass on boats and convertible rear windows that sit in the sun. It also has anti-fog and anti-static properties, so your windscreen or RV window stays clearer between washes and does not fog up on a cool morning.

Owners mention it works great on motorcycle fairings and UTV windshields, and some note that a single can lasts 2 to 3 seasons of regular use. One reviewer who uses it on a polycarbonate rear window calls it “pricey” but says it works amazingly and “smells pretty good.” It sprays as an aerosol, so it is easy to carry on the road, but at 14 fluid ounces its cost per ounce is higher than the 32-ounce bottle above.

One buyer called it a “great alternative for Plexus at half the cost.”

Designed originally for aircraft cockpits, this aviation-grade cleaner is scratch-free and puts it into a special tier of reliability for anyone with expensive plexiglass to protect. It reduces fog and oily smudges by leaving an invisible protective layer, making it ideal for delicate surfaces like LCD screens in a car or instrument panels in a boat. The formula is spray-based, plant-based, unscented, and safe around people and pets.

Customers note that it works well on UTV acrylic windshields, removing mud and sap and leaving a water-beading finish. One pilot who uses it on a Cessna 340 says their husband prefers it over the far more expensive Plexus brand. The main complaint is the bottle: one reviewer lost 80% of the product when the bottle tipped over and leaked, so you need to store it upright. At 16 ounces, it is slightly larger than the Prist aerosol at 13 ounces.

The gel polish that actually removes light scratches and cloudiness from plastic.

This is the only product on this list that is a polish rather than a simple wipe-on cleaner. The gel formula is designed to be rubbed into uncoated clear plastics to remove light oxidation, cloudy haze, yellowing, and fine surface scratches. That makes it fundamentally different from every other spray — you use it when your plexiglass is already damaged, not just dirty. It comes bundled with a microfiber cloth and a foam pad, so you have everything to get started on a headlight or a plastic convertible window.

Reviewers point out that it works excellently on older car cluster covers that are “splotchy and foggy,” with one owner saying it took “about 8 minutes from start to finish, very easy to use with great results.” A buyer with a 2014 Mazda got great results on cloudy headlights. However, it is less effective on severe hazing — a few reviewers found it did not completely clear badly damaged headlights, so it is more of a maintenance polish than a heavy-duty restoration. At 10 ounces it has 60% more product than the Rolite spray, but being a thicker gel it goes further when applied by hand.

Creates a dust-repellent barrier so you clean less often.

This spray is the best option for surfaces that sit on a shelf or in a display case — retail signs, 3D printer enclosures, or a glass case at an antique shop. What makes it different is the anti-static, dust-repellent surface it leaves behind, which actively pushes away fingerprints and dust so you are not wiping it again the next day. The formula is water-based, zero ammonia or alcohol, and completely non-flammable, making it safe for a workshop environment with hot equipment.

One buyer who tried water and glass cleaner first said both “were leaving residue and haze after drying” until they switched to this product, which “lifted all haze and micro dirt.” On the other hand, some buyers found it lacks real polishing power: an owner disappointed that it could not polish out small scratches gave it 3 out of 5 stars. It is a serviceable cleaner with a great anti-static trick, but priced similarly to the Prist at 16 fluid ounces with a lower overall rating of 4.2 out of 5.

An eco-friendly aerosol that meets federal test standards for aircraft windscreens.

This cleaner comes from a brand with deep roots in aviation and marine, where plastic windscreens are expensive and must stay optically clear for safety. It is a nonabrasive, anti-static foam safe on acrylic, stretched-acrylic, polycarbonate, and glass, exceeding federal test standards for windscreen cleaners. The aerosol can is smaller and more portable than the Lucasol spray bottle, weighing just 0.82 pounds vs 2 pounds, which is handy if you pack it in a flight bag or a boat glove compartment.

Shoppers say that it “wipes bugs away and leaves a streak-free windscreen,” with a pilot saying it works great on the windscreen of a carbon cub. It also works on boat plastic windshields and motorcycle windscreens. It has a bamboo scent which is unusual for a cleaner, and the formula is eco-friendly and safe around people, pets, and plants. At 13 fluid ounces, it has 23% less volume than the Rolite spray, and the weight difference (0.82 lb vs 16 oz) means you are getting more propellant and less liquid per can — the nature of an aerosol.

Spray it on, wait 10-20 seconds, and wipe off bugs like magic.

This is the go-to can for motorcyclists who battle bug splatters on every ride. The formula is specially formulated for windscreen surfaces and effectively removes bugs and debris with a simple spray-and-wipe application. Instead of scrubbing at dried bug guts, you spray, wait 10-20 seconds as one buyer described, and wipe off “bugs with ease.” It also works on faceshields, goggles, car windows, boat isinglass, and aircraft exteriors, making it versatile if you ride and drive different vehicles.

It is a 14-fluid-ounce aerosol in a wildflower scent, and it comes from an American manufacturer with a strong following — one buyer says they have used it for years and that it “won’t discolor plastic.” The main annoyance is the spray nozzle, which one owner says is “way too wide,” causing overspray onto the engine and passenger seat. It is a cleaner with light polishing properties, not a heavy-duty restorer like the Meguiar’s PlastX. At 14 fluid ounces, it sits between the Prist (13 fl oz) and Rolite (16 fl oz) in volume.
