STAR BRITE View Guard Clear Plastic Treatment
Best for boats operating in heavy weather or salt spray, this treatment is designed for Strataglass, EZ2CY, Eisenglass, and other clear plastics. It creates a water-repellent barrier that helps keep visibility high in rain and spray, while also shielding against UV damage that can cause yellowing or cracking. Ideal for boaters who navigate challenging marine conditions or frequent coastal trips. A potential limitation is the need for periodic reapplication to maintain performance in very harsh environments. Use this when you want maximum wet-weather visibility with durable UV protection.
303 Products Marine Clear Vinyl Protective Cleaner
Best for owners seeking comprehensive UV protection and prevention of yellowing and cracking, this cleaner offers lasting shield and gentle cleansing for vinyl windows like Strataglass and Eisenglass. It is designed to repel dirt and stains while preserving the surface’s clarity. Consider reapplication every few weeks in high-sun or salt-heavy climates for best results. This option favors long-term maintenance over a one-time polish, helping keep marine clears looking new longer.
Camco Plastic Cleaner and Polish
Best for a versatile spray that protects various plastics including isinglass, PLEXIGLAS, and vinyl, this product seals pores with a protective coating and helps prevent browning and hardening. It’s convenient for on-deck use and quick touch-ups. Choose this if you want a simple, spray-on solution for multiple plastic surfaces. A caution: results can vary with surface condition; deeper cloudiness may require deeper cleaning before polishing.
IMAR Strataglass Protective Cleaner
Best for Strataglass surfaces, this cleaner is formulated to clean, shine, and protect Strataglass with UV-resistant properties. It’s a targeted option for boat owners who rely on Strataglass for visibility. It provides a balance of cleansing power and surface protection. A potential limitation is that it is specialized to Strataglass, so users with other types of clears may prefer a more general product in the list.
Invisible Glass 92084 Clear Plastic Cleaner
Best for delicate plastics and anti-static protection, this cleaner is effective on vinyl windows, helmets, and other clear surfaces. It leaves a smooth, anti-static layer that resists dust and reduces micro-scratches. Opt for this when you need a gentle, streak-free finish on sensitive plastics. It may not offer the strongest UV protection compared to UV-targeted formulas, so pair with a dedicated UV guard if that is a priority.
Buying Guide
What should you consider when choosing an isinglass cleaner for boats?
- Surface compatibility: Match the cleaner to your clear plastic type (Strataglass, Eisenglass, vinyl windows, etc.).
- UV protection: If sun exposure is high, prioritize products with UV resistance to prevent yellowing and cracking.
- Protection vs. cleaning power: Decide whether you need a surface conditioner and protective layer, or a quick-cleaning spray.
- Reapplication frequency: Some products require more frequent use in harsh marine environments; plan maintenance accordingly.
- Ease of use: Look for spray-and-wipe formulas for on-deck convenience or specialized cleaners for Strataglass surfaces.
- Safety and residues: Prefer products that dry clear with no oily residue and are safe for marine clears.
How to apply for best results
- Clean first: remove salt and grime with a dedicated cleaner before applying a protective formula.
- Dry completely: allow surfaces to air-dry to ensure even coverage and avoid streaks.

Maintenance tips
- Schedule regular cleaning every 2–6 weeks depending on exposure.
- Reapply protective treatments after heavy weather or long saltwater trips.
