Marine Multi-Surface Cleaner, Boat Cleaner Spray for Vinyl, Canvas & Upholstery – Removes Dirt & Grime, Sunbrella Recommended, 32 oz

This stuff is THE magical unicorn of all purpose cleaners. I've read that Optimum Power Clean is also a great alternative, but I haven't used it yet. Beware that if you use it to clean your auto interior you will be absolutely disgusted by the amount of dirt and grime it will remove, even if you thought it was already clean. If your car is a "new to you" used vehicle that has never been professionally detailed (like $200+ detail, not just a coating of amour all that you think is a clean interior) you will be surprised to discover your interior's actual color after using this. I love that this stuff is not scented. It will remove any dirt/residue that is causing your car to smell (even if you don't think it has a smell, other people probably do, you just are used to it) and make it completely neutral, versus other products that you think are cleaning and just masking odors with stronger scents. This stuff is extremely concentrated. I would highly advise purchasing an empty spray bottle container with it. I have used it both 1:1 out of the container to clean one seat, and 20:1 (water:product) on a driver and passenger seat with years of grime. Needless to say, both applications performed identically. So there is absolutely no reason not to reduce it and make it last much longer, it works just as well. Some tips, part of the effectiveness of this and other professional all purpose cleaners is in the way you use it. For non-porous surfaces, it works well to spray it directly and let it sit, avoiding direct wetting of electronic components. You can use a soft brush to swipe lightly over the surface, but it is key to keep the area you are cleaning moist and not dry out. Let the product do the work and dwell on the area for a couple minutes, then wipe away with clean microfiber towel. For cloth surfaces like pillars and headliners you should spray the product onto a clean microfiber and wipe the surface, folding it to clean sections of the towel as it transfers dirt onto the towel. This way you don't over wet the fabric and damage the adhesive underneath. Areas on your headliner around the doors, the visor, and on the pillars around the door that are prone to getting dirty over years of skin oils and other dirt will literally look new again after even just a few wipes. Another product that you should get along with this is the 303 surface protectant. After cleaning with this, that stuff is one of the best things you can use to protect your plastic and vinyl interior. It leaves a nice unscented and matte finish that has uv protection on your interior.

Works great on our new pontoon boats seats, floor, and exterior.

Cleans the spa walls and head cushions with this product and it does a great job.

Decent cleaner, doesn't remove older stains but works ok on newer stains

This is the best fabric cleaner I have found. I have a performance fabric banquette that the dog dumped a plate of spaghetti on months ago. Nothing even touched the stain. After 1 application, it was much better and after the second, it is gone. Most stains take 1 application, but this really tough one took 2. It also handled hair dye on my daughter's white vanity chair. These were very old stains. It appears to brighten as well as remove stains. I am so happy I found this fabric cleaner.

I use this on a vinyl hot tub cover and on my car. On the cover, it does a great job on grunge, and works on most stains, less perfectly the ones the sun has baked in. On the car, it does a much better job on bugs and tar than other products (I'm thinking a nationally known bug and tar product). I understand that some people find it expensive, but a little goes a long way. Not often that I have to re-spray and re-scrub, again, not true of other brands as much. I'm also a big fan of their surface protectants.

I absolutely love this product. It is without a doubt the best and quickest stain remover I have ever seen. I use it on my rug and kitchen cushion seat pads. N

This worked amazingly for the boat!! I bought this is for my parent’s boat and their friends were so impressed they ordered it up for their boats too! All the other 5 star reviews were correct!! Seriously, this works like a dream!

Purchased the 303 fabric/vinyl cleaner because didn't want any conflicts between product brands, wanted to clean before reproofing with 303 fabric guard. used this to remove soiling that had been on the sunbrella canvas for many years, applied to stains then put in washing machine on cold to ensure washed and rinsed not sure supposed to use washing machine but this worked for me. the soiling was erased. applied the 303 fabric guard (separate purchase) to finish the water proofing. happy with the results so much that used the cleaner to wash a Tilley hat and reproofed with 303 fabric guard.

Use witb one oc those magic sponges and this really is the business. My TVR interior looks almost as it did when new 15 years ago.
