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

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 this in the past for our boats plastic windows. Got it for the plastic window for our convertible car windows. It really cleaned up the chalkiness and made it easier to see though. High quality stuff. It is highly recommended. Great value

This product does what they said it will do and the price is great. It brightens my plastic chairs that I have on the patio really well. There is no residue and it's so easy to use that I don't mind cleaning the chairs.

Impressed . The 303 vinyl cleaner works very well. No problems. Happy customer.

It's a good product.. But even better when combined with other plastic polishes.. For the price and certain job it ok .. Not for everything though

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