What is Boat Oxidation?

Wiping clean your boat is not enough for you to say that you have taken reasonable care of the vessel. The reason why a bucket of water and a mop aren’t enough for the proper care of a boat is evident in our boat detailing section of the Marine Mag website.

There we have created guides on getting the top products for every aspect of boat maintenance. Once you go through our work, you will quickly find out that many threats lurk around, and by that, we mean corrosion, filth, denting, scratches, etc.

Every problem can be remedied, but we need to put the correct diagnosis first. So how do we tell that we got boat oxidation on our hands?

Well, for starters, your boat will start losing some of its shine. The term professionals use “chalking”. This is what appears on the surface of the vessel, and it is a sure sign of oxidation. Also, yellowish stains may signal that it is time to obtain one of the products we have reviewed above.

How does Boat Oxidation Occur?

Every metal interacting with air will oxidize. Depending on the type of metal, the effects will be different. Heavy cast iron parts start rusting, but aluminum starts showing this chalky film on its surface.

It is highly essential to know that if you have a wooden boat, you got nothing to worry about as oxidation isn’t possible between wood and oxygen. Wooden boats, however, have another weakness, and it’s waterproofing. You want the surface to be perfectly sealed, so we recommend reading our expert reviews of the top marine epoxy money can buy.

Some residue will also be found on fiberglass surfaces over time. Even though fiberglass isn’t technically a metal, it will still show wear when exposed to sun and air. If you own a kayak or a canoe, it is likely made out of fiberglass. This article will also be useful for you because learning how to remove heavy oxidation from fiberglass will be quite handy.

Can Oxidation be Prevented?

Best Boat Oxidation RemoverThe short answer is yes and no. It is pretty much impossible to battle Mother Nature, but you can slow down this process. Not the battling, but the oxidation. The most important part is identifying the presence of oxidation. Here’s how you can “catch” the three main stages on time.

  1. Early oxidation signals. Your boat will start losing its shine. The surface will look somewhat dull and won’t be sparkly at all. Now, the reasons for this may be various, and a good old wash of the vessel may just do the trick.

Many times, some dust and debris represent the reason for the not so attractive look of your boat. Not everything will be related to oxidation, especially if your vessel is relatively new.

  1. The second coming of oxidation. Here you should perhaps start thinking of using a specific product to remove oxidation. You will be able to tell you need one because the shine will not be back even after a thorough scrubbing.

To make sure you clean your boat correctly, we recommend having a glance at our reviews of the most distinguished boat wash products on the market. See all the detergents we have outlined, use some of them, and then you will know that your boat is clean for sure. Again, if that fails to impress you, then we are talking about oxidation.

  1. Heavy Oxidation. It’s not too late to save your boat, but this is pretty much the red flag you don’t want to see. Your hull will start showing a film on its surface. If it’s a fiberglass boat, the oxidation will be represented by a gritty substance. At this stage, the only way to remove this chalk is by polishing the vessel with the correct product.

Benefits of Using a Boat Oxidation Remover

It is clear that you can’t leave your boat to rot outside. Actions need to be taken, and your best shot is obtaining an oxidation remover to do the job. Here are all the things you will achieve after making this smart purchase and start maintaining your Gelcoat properly.

  1. Deposits and chalky substances will be removed. You never want anything on the surface of your boat’s hull. No yellowish stains will be present, and your boat will start shining again.
  2. Oxidation removers can bring old boats back to life. Unless there is irreparable damage done to the boat, there’s no reason why you wouldn’t be able to breathe new life into it.
  3. The application of an oxidation remover is a must when you want to polish your boat afterward. For you to put the final touches, you must be sure that there is zero oxidation on the surface of your boat.
  4. Sometimes an oxidation remover is enough, and no use of additional products is required. See for yourself. If you like the shine of your boat, then don’t treat it with anything else after the oxidation remover.
  5. Simplicity is key. The whole process of applying oxidation remover barely requires any prep or knowledge. You need a couple of tools, and you will be ready to go.

How to Use a Boat Oxidation Remover?

We will now go through the simple process of applying an oxidation remover on your boat.

  1. Identify the level of oxidation you have. A couple of sections earlier, we mentioned the three primary levels of oxidation. To a large extent, this will determine the type of product you need. Newer boats with light levels of oxidation will require a light-duty product. Heavy-duty removers are to be sued only if the severity of the oxidation is high.
  2. Once you are comfortable with what product you will use, wipe clean your boat using a simple rag or a mop. Apply water and some detergent if you wish, but make sure the hull is dry before commencing with the remover.
  3. Pick the correct detailing tool. Oxidation removers are best applied using an electric cleaner. We don’t recommend doing everything by hand, especially if you got a lot of areas to cover. Use a buffer, and it will make all the difference in the world. Look for a buffer with as much fluff and softness as possible. Remember, we need to be as gentle to the boat as possible. Something that rotates in a random direction and has a foam wool pad will do the trick.
  4. After you are done buffing, nothing stops you from wiping the surface with a dry rag. That’s it, you are done!

Will my Boat Surface Always Recover after the Use of an Oxidation Remover?

There will definitely be some sort of improvement, but after many years of use, you cannot expect a boat to look as if you’ve just purchased it. Over time, the shine may stop coming back, but one thing is for sure, the hull will be in good shape.

The bottom line is for the body of your boat to be healthy and stable. If you care about the gleam of the hull, then we recommend also looking at our professional reviews of select boat polishes. Polishing the boat after buffing it will significantly help.
