303 Marine Clear Vinyl Cleaner for Isinglass & Strataglass, 32 oz

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.

This is an amazing product for vinyl windows. And that's what my review is for it's not for boats or anything else it's for vinyl windows when you put it on you do a section at a time using microfiber towel clean them then use a separate microfiber towel, I have puffy ones, to buff it. And I mean buff in little circles, not just wipe it off like you do with Windex. Give it a shot I think you guys will like it if you have the correct towels, which I've told you what to get, and the right technique, which I have already told you how to do. It helps repel the dirt, so when I'm out there cutting the grass and shooting dust all over the place it helps it not stick to the windows. And also has UV protection in it. You see my backyard I don't have trees and I could have used it 7 years ago when I bought this house because now I have some windows that have shrunk unfortunately. Try it I think you will like it. Some of those other reviews are talking about the cracked bottles or what have you. That is not about the product it's about the packaging. Try it it's amazing! My dog can see the squirrels clearly now, lol.

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.

I ordered this to renew a canoe that had seen better days as per the manufacturer's recommendation. There were scratches and dirt which, like magic, this 303 cleaner and polish took care of with little effort. The scratches and gouges still remain, but they aren't as visible, plus the product enhanced the color and shine of the canoe. I recommend reading the directions - don't use in sun, and don't over apply to avoid streaks and smears. Decent product and helped spruce up my canoe.

Works amazing on our Seadoo Switch vinyl panels. Just spray and wipe.

THIS PRODUCT TRULY WORKS WONDERS. Instructions On How to apply are straightforward, streak-free, & leaves no residue (very smooth & soft surface after applying). It holds up well and gives recommendation on how often to apply. The 32 ounce bottle size lasts a pretty long time. I have used same bottle, multiple times on our 3 kayaks. We’ll be doing our freshwater bass boat this year with it. A little goes a long way - no need to go crazy!! Just follow the instructions & you’re golden!! I do recommend using a microfiber cloth as they do as well - applies and dries very well. Appearance before and after using this product is clearly visible. I won’t ever use anything else after trying this when I purchased! WHAT ARE YOU WAITING FOR??!!

Great way to keep black vinyl clean in preparation for 303 protection. Both give a nice shine and appearance, however, good to do it at least every 2 to 3 months. They help protect from UV, but don’t last indefinitely.

This is a great product for our poly windows on our porch. This was the second time we ordered this product and first never arrived. But, this product does exactly what it is supposed to do!

Treated all the plastic windows in my boat.I have used other products that did a pretty good job, but this really made a difference.It seems to fill the small scratches, but the main improvement was that it made the windows very supple and flexible.The product is quite expensive, but well worth it for the results.

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