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.

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 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.

This was recommended to clean and protect my vintage Bernina sewing machine. The plastic parts Very happy to say I feel it has done the job

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

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

Buen producto

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
