Marine Clear Protective Cleaner - Cleans and Protects Vinyl and Plastics, Provides Superior UV Protection, Prevents Yellowing and Cracking, 32oz (30215)

Marine Clear Protective Cleaner is outstanding! It cleaned and restored my boat’s canvas far better than I expected. It easily removed dirt, salt residue, and light oxidation, leaving everything looking bright, clear, and refreshed. What really impressed me is how it not only cleans but also leaves behind a protective finish that helps repel water and grime. The shine it brings back to clear surfaces and trim makes the boat look well-maintained and almost new again. It’s simple to apply, wipes off easily, and doesn’t leave any streaks or haze. If you’re looking for a reliab

I started using this on the sides of my hot tub after the sun began fading and dulling the original finish. The constant sun exposure was really taking a toll, and this did a great job bringing the look back while adding protection. I recently tried 303 Products Marine Clear Protect, and I’m genuinely impressed. It does exactly what it claims—creates a protective barrier that helps prevent fading, chalking, and oxidation. I used it on my boat’s gelcoat and upholstery, and everything looks noticeably cleaner with a deeper, richer finish. Application couldn’t be easier—just spray it on and wipe it off. No greasy feel, no streaks, and it dries quickly. I also tested it on my car’s trim and tires, and it restored a clean, like-new appearance that’s held up well against sun and rain. If you’re looking for a versatile protectant that actually works and helps keep surfaces looking great despite harsh conditions, this is a solid choice. Definitely recommend.

Great cleaner and protectant—I used it on outdoor gear and it really restores and shields surfaces. Works just as well as the premium brands, but at a nice price point. Quality is dependable and I’ll keep buying this one.

This works fine for cleaning the vinyl windows in my lanai. I’m not sure it cleans any better than water alone, but I use it hoping it helps protect the vinyl.

Perfect for my Bronco with marine-grade leather. It provides durable, long-lasting protection and helps keep the seats looking great over time. The spray absorbs well and leaves no greasy or slippery residue, which I really appreciate. It’s far more cost-effective than frequent detailing—I just spray and wipe as needed. Shipping was smooth, and the bottle arrived well packaged with no leaks. Very happy with this product.

Used on my Hobie kayaks, leaves nice finish, helps clean.

I’ve been using this 303 Marine Clear Vinyl Protective Cleaner on various outdoor surfaces around my boat, RV, and patio furniture, and it’s easily one of the best products I’ve added to my maintenance routine. This cleaner does a great job of lifting dirt, grime, and light oxidation from vinyl and clear plastic surfaces like Strataglass, Eisenglass, and other marine windows — and it doesn’t leave behind streaks or a greasy film. It’s also safe on vinyl and plastics, with a formula that avoids harsh solvents like alcohol or ammonia. What really sets it apart is the UV protection. After cleaning, the treated areas feel like they’re sealed against harmful sun exposure, which helps slow down yellowing, cracking, and brittleness on surfaces that get intense sun all day. That’s especially useful for clear vinyl panels that can degrade quickly when left untreated. I also appreciate that it leaves a natural, non-streaky finish — surfaces look clean without an artificial shine, and you can tell the protective layer is actually doing something rather than just sitting on top of the material. Application is easy: spray on, wipe with a microfiber cloth, and you’re done. I’ve used it on boat enclosures, motorcycle wind screens, and even patio vinyl cushions — and the results have consistently kept those surfaces looking newer and clearer over time. Overall, this cleaner is a solid investment for anyone who wants to maintain and protect outdoor vinyl and plastics, and I’d recommend it for marine, RV, or outdoor living use.

Although this has been a good overall cleaner (remove dirt, suntan lotions, sweat) for our boat seats, it does not remove mildew. I had mildew in the cracks of the seat and was trying to scrub it off, and it did nothing to it.

Does everything it states it does. Leaves vinyl well conditioned an protected

This stuff is great!! I used it on my boat windows and on my Argo windows. It seems to soften the vinyl and when you look at the windows after, you think they are brand new. Definitely clean the windows before with water and remove them from the vehicle first. You will be surprised how great the windows will look after!

Fantastic product, follow the instructions and it will restore your vinyl windows to brand new

Liked the ease of use. Used to re invigorate a vinyl spa cover. Very pleased with the result
