Boat Polish Test: One-Step Cleaner/Waxes

For this boat maintenance test, PS editors ditched the buffer and applied 11 one-step cleaner/waxes to three boats to see which would give the gelcoat that just-polished shine. After three months, five cleaner/wax-treated sections are still glossy and bead water.


At Practical Sailor, were always looking for boat maintenance shortcuts. Typically, restoring and protecting an oxidized hull is a two-step process, compounding with a mild abrasive, followed by waxing. This time, we looked for the lazy-mans approach-so-called one-step cleaner/waxes. Among the contenders: Collinite 870, Meguiars 50, Restructure Marine Polish, Meguiars 67, 3M Fiberglass Cleaner Wax, 3M Clean & Shine, Interlux Premium, West Marine One Step, Star brite Cleaner Wax, and Simoniz Cleaner/Wax. After three months in the Florida sun, the shirkers route is looking pretty good.



Amazingly, there are still marketeers who tout fiberglass as a maintenance-free material. It is, as any sailor knows, anything but. Deterioration begins as soon as a hull emerges from the factory shadows. The blessed sunlight that makes sailing such a pleasure immediately begins gnawing away at any unprotected gelcoat, the

One-Step Cleaner/Polishes


mixture of resin and pigment that is a fiberglass boats frontline defense against the elements.

Ultraviolet rays and oxygen speed up the oxidation process, which literally wears away the gelcoats binding resins, leaving only pigments behind. When you drag your hand across the surface of a heavily oxidized hull, the chalky substance youre picking up is actually the remaining pigment particles.

Waxes and polishes combat oxidation by sealing out oxygen and, in some cases, inhibiting UV rays. For 30-plus years, one of the most engrossing projects here at

Practical Sailor has been searching for the ideal armor for gelcoat inexpensive, easy to apply, and long-lasting.

Typically, restoring and protecting an oxidized hull is a two-step process, compounding with a mild abrasive, followed by waxing. The last time we looked at waxes (“Wax Test Results” Nov. 15, 2004), we looked at products whose primary purpose was to serve as a protective coating after any old wax, unbound pigment particles, dirt, grime, and oil had been removed by compounding and polishing. This time, we looked for the lazy-mans approach so-called one-step cleaner/waxes that combine the compounding and waxing processes.

Although many products call themselves cleaner/waxes, the directions on most of the products we tested call for a clean and dry hull before applying. This just means you should rinse off surface dirt before applying the product to keep the grit from scratching the gelcoat. The cleaning action in a one-step cleaner/wax is primarily a mildly abrasive scrub aimed at removing oxidation, deep stains, grease, or oil that can’t be removed by detergents, a sponge, or a brush.

What we tested

We gathered 11 one-step products for this test, all of them aimed at the “marine” market, which means we can probably find similar (if not the same) products for less money at local automotive stores or major retailers. Once we find our best in this field, well jump into the non-marine world to find a worthy competitor (any suggestions from readers are welcome). These dual-purpose products combine cleaning and polishing materials (a wetting agent, mild abrasives, and surfactants to dissolve oils) and protective sealing agents (typically a carnauba wax or polymer coating), and, in most cases, a UV inhibitor. Unfortunately, nearly all of them have petroleum-based ingredients. Most of the manufacturers told us that their “one-step” products will not last as long as their premium wax or polish, but offer a good alternative for those who want to protect their boat, but could do without the exertion of a buff-and-wax routine. (In other words, these products are aimed squarely at the shirkers among us who just want to get on the water and are quite content with a less-than-perfect finish.)

Not surprisingly, our test group featured several manufacturers with a history in the automotive wax/polish market (Collinite, Simoniz, Meguiars), or like West Marine and Interlux, are household names in marine maintenance. The one unfamiliar name was Re-Structure Marine, a company based in California that makes some pretty bold claims (three years of protection!) regarding its new products, which they say uses nanotechnology (science that controls matter on a scale smaller than one micrometer). Several manufacturers offer one-step clean and wax products that are more abrasive than the ones we tested, but we tried to keep the field limited and didnt want to unduly buff off good gelcoat, an important consideration for any boat owner.

Collinite 870


Most of our test products were thick liquids in squeeze-top bottles: 3M Marine Fiberglass Cleaner and Wax, Meguiars 67 One Step Compound, Meguiars 50 Cleaner Wax, and Re-Structure Marine Products Professional. Two were pourable liquids: Collinites 870 Super Heavy Duty Fleetwax and Interlux Premium Teflon Marine Wax with Cleaner. We also had one spray, 3M Clean and Shine Wax Enhancer, and one paste, Simoniz Royale Marine Cleaner/Wax. We also tested the Interlux Premium Teflon Marine Wax in combination with its UV Protectant & Teflon Wax Sealer, which is to be applied after the cleaner/wax. Technically, this makes a two-step process, but hey, a sample of the sealer came free with the bottle of wax, and we were curious. (But after applying each product by hand to three different boats see “How We Tested” we were happy to keep the number of steps to a minimum.)

What We Found

After three months, the lazy mans route was looking pretty good. Our top five one-step polishes were holding up just as well as a premium two-step finish (Collinite 885, which was our top pick in the wax test) that was applied to one of our test boats at the same time as the test products.

Five products that stood out for their cleaning ability, gloss, and their ability to bead water: Starbrite Cleaner Wax, Collinite Special Heavy Duty Fleetwax, Re-Structure Marine Products Professional Marine Polish, Meguiars 50 Cleaner Wax, and Simoniz Royale Marine Cleaner/Wax. The three-month results are summarized in the following text and chart. Stay tuned for the six-month update.

Collinite 870

Touted as “almost indestructible,” Collinite 870 is a runny liquid that comes in a screw-top bottle. It was the

second-most expensive product in our test, and its pour application and thin consistency made it slightly messier to work with. Testers
Interlux Premium Wax


were briefly stumped by Collinites instructions that suggested using a Turkish towel. (From a Turkish bath, perhaps?) We chose to use a terry-cloth towel, but a cloth diaper would work as well.

Bottom Line:

This was the only one-step tested that was unanimously rated the best initial finish. It also seemed to take less effort to achieve that gloss. And the shine has held up well after three months.

Interlux Premium

Like the Collinite, the Interlux Premium Teflon Marine Wax with Cleaner is a runny liquid that is slightly messier to apply than the pastes. This is the only product in our test that touts Teflon (a Dupont trademark that requires paying royalties to use in marketing). However, several other products (Collinite 870 among them) use the chemical equivalent, PTEF.

Our first application left a hazy swirl mark like the kind youd leave on a hastily washed window or mirror visible from about 1 foot away. We reapplied the product the following day on a different section of the hull, and had the same results. On an adjacent taped-off section of the boat, we applied the UV Protectant & Teflon Wax Sealer with slightly better results. At the three-month mark, only the section with the sealer still beaded water. (See pictures, p. 31)

Bottom Line:

Middle-of-the-road performance. If you are going to use this product, use the UV Protectant and Teflon Wax Sealer as well.

3M Clean and Shine

We havent had much luck with spray-and-wipe waxes (pastes have long been a

Practical Sailor favorite for durability), but we figured maintenance-giant 3M might have the expertise to pull it off with its Clean and Shine Wax Enhancer.

Carnauba wax is one of this products listed ingredients. It was the only product that allowed application on a wet hull, which made the product even more appealing. Hose the boat down, spray, wipe and voila! Too good to be true?

Bottom Line:

This was an unexceptional cleaner. It left a moderate gloss that did not last to the three-month mark. Like the Interlux wax sealer, it seems this is best used over previously waxed surfaces.

3M Cleaner and Wax

With the thickest consistency of the flip-top bottle products, 3M Marines Fiberglass Cleaner and Wax, required vigorous shaking to dispense easily. Combining a light rubbing compound and a blend of carnauba and other waxes, it was one of the few products that directed us to “rub aggressively using straight, short

One-Step Cleaner/Polishes


strokes.” It also told us not to let the product dry to a haze before wiping away: Just keep rubbing until the material is gone. Most of the other test products advised applying in a circular motion, letting it dry, wiping, then buffing. This product also comes in paste.

Bottom Line:

This was a more vigorous cleaner than the Collinite or Interlux, and the finish rated high for initial gloss. Though it retained good gloss and still beaded water, the 3M was not among the top performers after three months. Too much work, not enough shine.

West Marine One Step

In a flip-top bottle very similar to those used by Star brite, West Marines One Step Fiberglass Cleaner Wax was runnier than the other flip-top one-steps. Application was fairly easy, and the gloss stood out to one judge. But, after three months, gloss was unexceptional and water ran off the polished section in big drips.

Bottom Line:

Another mediocre performer that isn’t worth any pennies you might save.

Star brite Cleaner Wax

Star brites Heavy Duty One Step Cleaner Wax was one of the least expensive test products, and at three months, the section polished with it was looking very good. It picked up a lot of oxidation on our rag during application and provided one of the glossiest finishes.

Bottom Line:

A good cleaner that was still beading water after three months, this is hands-down our Budget Buy.

Meguiars 67 One Step

Labeled as an aggressive compound cleaner plus polish, Meguiars 67 One Step Compound clearly seemed to lean toward the “cleaning” side of the cleaner/wax continuum. The thick liquid picked up stains and oxidation, but not as aggressively as wed anticipated. Even on the heavily oxidized Javelin, it did not stand out in the field for its cleaning ability. At three months, it was clearly not beading water.

Bottom Line:

A big step behind Meguiars 50 liquid cleaner/wax.

Meguiars 50 Cleaner wax

Meguiars Mirror Glaze 50 paste wax was the second-best product in our wax test, so we had high hopes for this product. It touts anti-corrosive properties to fight rust, so we also put some on our test boats rust-prone stainless steel folding ladder. In terms of consistency, this was the best of the products tested, not so runny as to be sloppy, not so thick as to dispense in gloppy burps.

Bottom Line:

Excellent cleaner, and very good initial gloss that held up well at three months. Its a Recommended product.

Re-Structure polish

Introduced in 2005, Re-Structures Professional Marine Polish is effectively a marine version of what is used to protect some new cars. The bottle guarantees a three-year finish, and according to the company, the finish is advertised for five years on cars. The products penetrating and cleaning agent is MBSilane, and its other ingredients seal the fiberglass to keep out dirt, grime, and UV damage.

Bottom Line

: This is expensive stuff, but it works. It does not clean as well as some of the more abrasive products we tested, and its initial gloss was not quite as shiny as the Collinite. But at three months, this finish was beading water like it had just been applied. Recommended.

Simoniz Cleaner and Wax

The Simoniz Royale Boat Cleaner and Wax was the only paste wax/cleaner in our test, although 3M, Star brite, and Collinite make paste versions of their cleaner/waxes. (Well report on these in a future update.) As the results of our previous wax test bore out, pastes trump liquids when it comes to durability, and they are also less messy to apply. This paste went a long way and did a good job cleaning rust and waterline stains.

Bottom Line:

Simoniz delivered an easy-to-use paste that holds up over time. Given the results of our wax test, its performance was no surprise.


Overall, we were surprised with our results after three months. Wed expected none of the products to still be beading water after continuous exposure to the Florida sun, when in fact, few of them werent. Will the best gloss so far Collinite 870 satisfy the person who is looking for a shine that turn heads? We think so.

Our Best Choice, Collinite 870 is the gloss champ at three months, though the dark horse and recommended polish, Re-Structure Marine Professional Marine Polish, is beading water as well or better than the Collinite. We also recommend Star brite Heavy Duty Cleaner Wax, Meguiars 50 Cleaner Wax, and Simoniz Royale Marine, which are all neck-and-neck at this point.

Except for Re-Structure, most manufacturers say six months of Florida sun is about the limit for these products. Well see.
