RMR Marine Bilge Cleaner, Professional Strength Cleaning Wash, Odor Remover & Protectant, Safe & Sustainable Boat Maintenance Supplies, 24 Ounce Spray

If you need to clean a large bilge, you probably want a larger quantity than a small spray bottle. If you have a smaller bilge, or just need to stay on top of a mostly clean bilge with a wipe-down, this is perfect I used this on my sailboat's bilge, which is mostly clean, but over a season it gets dirty. This product brought it to a white finish with a light wipe rather than requiring a lot of scrubbing as other products have required. I also sprayed it on a few hoses which were grimy, and was able to bring back a better look. I love that this is made in the USA, and feel it does a great job of loosening up bilge crud.

I had a really dirty bilge in my Parker 23 (slipped at the ocean). In order to access the bilge I have to reach through two doors in my transom, which makes it a bit tricky to get to. As a result, it is usually very mildewed and dirty. It had been probably two years since I last gave it a good cleaning, so I used this product to clean things up. I noticed a couple of things - first of all the sprayer produces a very fine mist - I wish that it could be a bit more directed - this fine mist means you have to be very close (within 4") to the surface you want to clean. When things are at a weird angle (like in my boat) it means you have to reach way down in there with the sprayer to make sure it is pointed at the right surface. I found that once I was able to hit the right surfaces and let is soak for a few minutes, a quick brush with a long, soft-bristled brush got things really nice and clean. It removed both black mildew and the film of grease/oil that was all over the interior if my bilge. I then turned the hose on it and got everything very nice and clean. One thing I noticed the following day was that my right forearm developed a mild rash. I attribute this to the fact that my arm was down in the bilge (reaching through the access doors) as I was spraying the fine mist of this cleaner all over everything. My left arm developed no such rash, so I'm figuring that it was a reaction to this cleaner (combined with perhaps some micro scratches from contact with the edges of the transom access doors, which are made of starboard, not fiberglass). The rash went away in about 48 hours and didn't give me any other problems. The other thing I noticed was that in between sprayings, when I would stick my head down into the access door to see what I'd missed, or to redirect my cleaning efforts, the fine mist suspended in the air was pretty irritating - I detected a faint odor of something that smelled like ammonia. So if you have an enclosed space, be careful of the fine mist that this spray produces. With all that said, it worked very well, and I will continue to use it, particularly because it is bio-degradable, which is very important since my boat is slipped in a marina, and any cleaning products I use end up in the ocean.

I've used other bilge cleaners in the past so I was a little reluctant in trying this one since I was not familiar with this company but was very happy with it's performance. It did a nice job of cleaning out the area below the engine, and for the most part is was spray and rinse. I do have some rough fiberglass areas that needed a little scrubbing with a brush, after spraying the area with the cleaner I used a soft brush on the rough areas and it cleaned the areas nicely. The cleaner has a pleasant fresh scent.Overall I'm very happy with it's performance and rate it as good or better than any other name brand bilge cleaner.

This was shockingly easy to use. Spray removed grime, grease, algae, mold, and water marks with relatively little elbow grease and no water on smooth fiberglass and plastic surfaces. Also worked cleaning long-abused plastic car accessories and truck headlights. A little (light misting) goes a long way. In a few cases, a second application was necessary. While I haven't tried this on a rough surface; it should work with a brush. The cleaned surfaces appear to be water repellant in subsequent rain. Works better than I could have expected from an online purchase.

Didn’t really notice any harsh chemical scent. Does the job just as good as any other cleaner would do!

A great way to keep the bilge clean. It degreases well and the sprayer makes it convenient to keep at the boat. I plan to use this a couple times a year or at least at end of season to keep the bilge clean. I used this yesterday and found it to be a very powerful cleaner when degreasing something I had previously sprayed with WD-40. It works great!

My bilge was so dirty, but this spray cleaned it right up! It doesn't take much scrubbing and cleans everything thoroughly. It made my job much easier.

This cleaner is easy to apply, it doesn't dull paint or gel coat, it dissolves many kinds of dirt and grime, it is easily cleaned with water, and it doesn't smell bad. This is a very effective cleaner.
