Boat Brite Hard Water & Mineral Deposit Remover

Our boat water spot remover quicky liquefies stubborn calcium deposits and all other hard water/mineral spots and buildup on all marine surfaces, including boat hulls, outdrives, clear vinyl enclosures and glass. Also works great on saltwater buildup.

  • Allows you to quickly wipe away boat hard water spots, mineral spots and dried salt water film build-up, from all onboard surfaces including clear vinyl enclosures and glass.
  • Breaks down and liquifies build-ups of calcium, magnesium, lime or salt - fast!
  • Extensively field tested in a variety of water conditions and regions of the country with excellent results.

Many freshwater lakes are mineral-rich. These minerals, when dry, end up as "spots" on the windshield or clear vinyl enclosure or as a "crust" on our hulls and outdrives and are very difficult to remove. The right chemistry is needed. This “hard water” is likely dried calcium, magnesium, lime or iron.
I keep my boat on a bay off Lake Ontario that is especially rich in calcium. This along with our field testers from MN, IN, MI, NC and FL have tested the product on all possible hard water/mineral scenarios found in our waterways here in the US and Canada. All of the testers and myself are very pleased with the ease and quickness of the removal of spots and buildup using the
Hard Water & Mineral Deposit Remover.

If your boat is in salt water we all know that without a regular wash down of the salt buildup, a crusty opaque film will develop -especially on glass and clear vinyl enclosures. We tested the product in the waters of coastal North Carolina and even boats left unattended for over a year where the salt build-up on the glass, clear vinyl enclosures and all fiberglass surfaces was sunburned in and rock hard, we cleaned this build-up quickly and easily! GREAT STUFF!!!!

Please Take a Moment to Watch the Boat Hard Water & Mineral Deposit Remover Video for Application Techniques

As with most boat water spot remover cleaning products, it works better when used with water – be it on a wet surface, with a wet applicator or both. I suggest both when using the Hard Water & Mineral Deposit Remover… here’s why.

Have you ever sprayed a cleaning product onto a dry surface of a boat and it “streaks” the surface? This is due to the cleaning agents in the product emulsifying the surface dirt/residual while losing their battle against gravity - sliding down the surface – cleaning as they descend. If the surface is wet, the streaking is reduced as the water disperses the cleaner.

After years of using the Boat Brite Hard Water & Mineral Deposit Remover, the following are the instructions for achieving the best results… and the application method is shown in detail in the product video on the website.

1) Prepare a bucket of soapy water.

2) Use a blue “all-surface-safe” or “non-stick cookware-safe”, etc. sponge – these are available at drug and grocery stores. Scrub lightly using the soft side of the sponge for light duty buildup or the “scrubber” side of the sponge for significant buildup.

3) Wet the surface.

4) Spray product onto mineral buildup and allow it to sit on surface for a minute or two.

5) Wet your sponge with soapy water (sponge should be lightly wrung out so it is wet but not saturated and dripping water). Then spray some product onto the wet sponge. On a vertical surface immediately begin lightly scrubbing with your prepared applicator. On a flat surface (deck) pre-spray the buildup and follow with a soapy water wash-down with a deck brush.

NOTE: Be sure to rinse the boat decks well before cleaning to remove loose dirt but more importantly, so that the "drain channels" that run down the side of the hull are wet eliminating streaking as mentioned above.

6) After scrubbing, allow the soapy water & product to sit on the surface for a minute or two, and then rinse.

TIP: Lightly wipe the surface with the wet sponge or deck brush while simultaneously rinsing to assist in removing all the mineral buildup.

NOTE: Some mineral residual that has been on the surface for extended periods of time may need a 2nd application. I’m sorry to say but some mineral residual (iron) is very stubborn and impervious to the Boat Brite Hard Water & Mineral Deposit Remover. Please call me if you experience this.

Captain John,
Your Hard Water product is amazing. I tried all the brands at Home Depot which didn't work. I took a chance with yours and I was instantly amazed. My boat is completely clean and no more ugly mineral film and spots. And then I applied the YachtShine Phenomenon and the metal flake paint on my bass boat just sparkles - like a sky at night!
I am singing your praises to all my friends!

Captain John,
You shipped me a bottle of Hard Water and Mineral Deposit Remover last week. 


From Collin

The entire hull is water spot free and is looking fantastic. Next visit I'm going to get the surface warm enough to apply a couple coats of polish and see how she turns out. I've been spreading the word about your products to everyone that stops by to see how I'm making my girl look so good. Thanks again for all of the info and I'll let you know how things turn out. 


From James and Judy Shannon,TX.

Captain John,
We received our order and used the hard water and mineral deposit cleaner.  It is amazing!  All of the film just melted off and left our boat shiny and sparkling.  The cleaner for the vinyl seats works like a miracle too.  Our seats looked dirty and nothing I used would clean them but your product did!  Our seats look like new!  I am so thankful my husband found your products while searching online.  I wish I had taken before and after pictures so you could see the difference.  Thank you. 


From Nishanto,  Simsbury, Ct.

As you know I ordered your product called Brite Boat because the water coming from my sprinkler system stained my house.  My house is vinyl sided.  The water hit a good portion of the side of my house including a 6ft sliding glass door and two other windows.  I tried to clean it off with the strongest of detergents including straight bleach.  Nothing I tried worked.  I was extremely upset and thought I would have to replace the windows as well as the siding. I came across your product by doing some research on the internet.
When it arrived, I immediately used it on the house and within 15 minutes what seemed impossible to clean, came off with just a wipe.   A real miracle.  
Captain John you have saved me a lot of money and aggravation.  My suggestion to you is that you market this product for cleaning bathrooms, and anything that has hard water stains.
The average householder should know about this product, not just boat people.
I am so glad I have it,  I will let many people to know about it.
Thanks so much   This is truly a five star product.


From Captain Richard.

Hey Captain John, After we spoke on the phone I followed your advice and bought the Hard Water product. I sprayed it on my boat and I couldn't believe it. The crust and spots that I got from Lake Michigan vanished and they were on there since last summer. Thanks for making such a great product and thanks for all the good info you shared with me on the phone.


From Trevor.

Effortless cleaning!!
Our ski boats are in and out of the river 5 nights a week, this product has made it so easy to remover the hard water spots from the river we spend a lot less time cleaning boats. I would definitely recommend this product to anyone that enjoys a life on the water.


From unknown.

We had a 14 year accumulated crust of mineral(magnesium) deposit on the hull of our lake boat from being in the water all summer. Last year I decided to try to get it off. I could only scrape it off with my fingernails. I tried 5 different products and a buffer, all to no avail. After I read the reviews of Boat Brite Hard Water and Mineral Deposit Remover I decided to give it a try. I was amazed that there was hope and the product did indeed cut through that crust and our boat looks new again.

Hard Water cleaner is amazing!
This year, I went to work as soon as the boat was out of the water. In 4 hours, it is looking great. I am very grateful. Also, I used this on the shower, toilet and sinks in my house and am delighted with the results, shiny and new looking again. I followed up the cleaning with an application of Yacht Shine. What a great product!
I tried the product this weekend on some older streaks on a boat I purchased used last year.  It had been in a hard water environment for several years and I was afraid nothing would remove the streaks.

I’m pleased to say the product performed quite well!  A few ounces and a little rubbing, and my pontoon boat is streak-free!
I stopped into the marina where I purchase most of my boat products and recommended they carry Boat Brite (assuming you distribute to stores).  You may hear from Devils Lake Water Sports in Manitou Beach, MI.
I also must add that the handwritten note with the product sets you apart from all other internet retailers I’ve used.
Thanks again!


From Karen.

Thanks, Captain John - it arrived on Friday and I used the hard water product with good results on a fiberglass shower at our cabin that had significant hard water buildup on it.  Looks almost like new!


From Boyd Reynolds.
Dear Captain John,

   I had recently ordered a bottle of your Hard Water & Mineral Deposit Remover and I just wanted to let you know that your product worked like a charm!  I had purchased a used boat and it had this hard white thick crust all along the waterline of the hull & motor. The previous owner said he had tried everything he knew of to remove it unsuccessfully & thus I purchased the boat at a discounted price. I then tried everything I could think of, unsuccessfully, & was just about to give up & just live with it when I came across your website. I have to admit, I was quite skeptical that your product would work any better than the numerous products I had previously used. I was amazingly shocked when I applied it to the first little test spot & the white crust just came right off! Now my boat looks like new again. Thank you for an amazing product, & I will be trying some more of your products in the future.
Thanks again.
