Who Needs a Boat Hull Cleaner? What are the Benefits?

Best Boat Hull CleanerWell, you probably already saw the answer to that question, and yes, it’s everybody that owns a boat. Of course, you do not need to clean the hull of your vessel, but then you will be the person with the filthy boat. And a dirty hull is just one step away from a damaged hull.

Boat care is vital, and it is not related only to looks and cosmetics. A well-maintained vessel will also last longer, and we at the Marine Mag know that from experience. Check out our page devoted to boat detailing and maintenance and see other products that will help you keep your boat in top condition.

So, let’s dive in the benefits of utilizing a boat hull cleaner:

  1. Everything that’s clean is also sturdier and plain healthier. It’s the same with every piece of machinery that we own. Your boat will be able to withstand more wind and sun when you make sure that the hull is sanitized.

Also, the bottom of the boat will be in top condition as well. This is why we recommend wiping your boat when it is out of the water. It’s best if you address every little part of the hull and especially the bottom as there are many benefits of cleaning it too.

  1. Performance of the vessel. This is not a joke. A clean boat will be able to cut through the water with additional ease. This is because filth will increase the friction between your boat and the water. Nothing in the world that is aerodynamic is also dirty.
  2. It will look good. Not everybody cares about how beautiful their belongings look, but the majority of people do. You simply cannot afford to show off with a dirty boat. Even though it spends time in the water, it doesn’t clean itself. Dust and particles will settle down and will inevitably mess up the good looks of your prized possession.
  3. What if you want to sell it? They say that a person is happy with their boat on two days in their life. The day you buy it, and on the day you sell it. Well, great, but how are you going to sell a vessel with a filthy exterior. It is proven that cleaning a boat increases its value. Don’t sleep on that.

The Most Popular Types of Boat Hull Cleaners

Boat Hull Cleaner ReviewsThe solvent that you use to clean your boat may come in a few shapes and sizes. They are all viable options but depend on a few things – mostly on your own preference and the nature of the boat hull you are about to clean. These are among the basics of cleaning a boat. So now that we’ve gotten this out of the way let’s see what your option are in terms of substance.

  • Gels – if you opt for such a solution, you probably have an aluminum or a fiberglass boat. This type of cleaning substance is good with smooth surfaces. Gels are quickly absorbed into the surface, and this is why using them on wood may not be a smart idea as you will get little coverage

Cleaning gels will rarely produce foam, and this is why we recommend you apply and spread them using a damp cloth. Using a brush on an aluminum boat is okay, but only if it a gentle one. Don’t be too aggressive with it as you may leave some scratches behind, and this would be disastrous.

  • Liquids – these are perhaps the most popular type of detergents used for hull cleaning. Most products are meant to be mixed with water. This means that you can even power wash a boat using a bar of liquid soap, although that’s not a very popular thing to do.

Such substances are good with wooden boats. You get a lot of coverage from them, and you can even use a brush. Again, we recommend that you are gentle with it and never go overboard (pun intended).

  • Powders – getting such a cleaning solution can be a little bit tricky as you always have to hit the right substance-to-water ratio. Sometimes powders are mixed with gels to form a paste. In any way, if you can feel the particles, that means they are not very well dissolved.

Utilizing powder can produce excellent results as it can remove even some very stubborn filth and particles. Knowing what to do is vital because you may end up damaging the hull.

  • Spray cleaners – products of that type are relatively new to the market. They can be useful but definitely not on wood and definitely not in very spacious areas. Sprays tend to dry out relatively quickly, so you need to be quick to wipe them.

Some of the products will create foam, which can be seen as an advantage. Unfortunately, you may end up burning through cans quickly, meaning that you will need to spend more money on cleaners.

Features of Boat Hull Cleaners to Watch For

You can’t just blindly purchase a bottle of detergent for the hull of your boat. See what the most important aspects to bear in mind are.

  1. The material of your boat. Most boats nowadays will be aluminum or fiberglass. While both surfaces are smooth, you want to purchase a cleaning product suitable for the given material. This is because most solvents designated for metal may turn out to be too abrasive for a fiberglass surface.

When it comes to wooden boats, we recommend getting something specially designed to polish wood. This is the first step in determining the appropriate cleaning solution.

  1. This is not only about the ease of use but also about how the detergent is applied on the surface. Brushes are not always the most suitable tool, but sometimes you have to dig in and scrape.
  2. Read the instruction and the contents sheet carefully because you cannot risk the solvent damaging your boat. This is also important to your health. Some detergents may require the use of gloves and even goggles. Make sure you are aware of what inside that bottle and whether it is abrasive or not.
  3. Many people do not bother to find out how long it should take the detergent to fulfill its effect. Some inpatient fellas wipe the solution away too quickly only to find out that their hull is still dirty. You have to know what the response time of your solvent is.

How to Clean a Boat Hull

There is nothing special here, but you still have to follow the steps thoroughly.

  1. Rinse off the hull before doing anything else. You can use either a hose, a pressure washer, or simply a bucket of water to do so.
  2. Apply the detergent on the hull of the boat and follow the instructions on the bottle.
  3. Use a sponge, a piece of cloth, or a brush to spread the solution over the body of the vessel.
  4. Rinse everything off after scrubbing
  5. Polish your boat using a buffer. We recommend you check out our reviews of the finest boat buffers You can never have too many useful tools.
