What is Boat Wash, and How Does it Work?

Best Boat WashThis is a cleaning agent that is designed to eliminate the filth and grime that boats suffer from. Such are bird droppings, scum, saltwater stains, fish blood and smell, and general dirt and grime. Some products are designed to treat specific parts of a boat, while there are versatile ones that are good to use on various surfaces.

The more versatile the product, the more you get for the price since with one product, you can treat most, if not all surfaces on your boat. However, that may come with downsides such as decreased strength. So, you should decide if you need a specialized and a strong product, or a mild generic soap that you can use on the interior and exterior of your craft.

It may sound a bit intimidating at first, but boat cleaning isn’t that complicated. All you have to do is follow the product’s instructions.

Why Do You Need to Use a Boat Wash?

Regardless of whether your boat is brand new or second-hand, it needs regular cleaning and maintenance, just like your car. It’s also important where you sail – in fresh or saltwater. Both have different effects on all boat materials, like causing mildew and oxidation. Paint can become scratched, yellow, or stain if you don’t take care of your vehicle. After some time, your boat looks old and dingy, not to mention that seagulls leave their acidic droppings all over your ship which are unsightly and can damage the paint.

That being said, keep in mind that there are boat washes intended to work on salt or freshwater. So, whichever you need, there’s a product for you.

Key Features to Lookout For When Buying a Boat Wash

Boat Wash ReviewsThe first and most important thing to consider when choosing a boat wash is not the cleaning product itself but your boat. Soaps are made to treat a range of materials that boats are made of. So, you need to find a product intended to use on the materials on your boat. If yours is made mainly from fiberglass and wood, that’s what you need to use on the boat. However, if you need soap for an inflatable unit made from rubber or fabric, you should select a milder product that won’t damage it.

So when you are sure about the material or materials you need to clean, then you should be on the lookout for the following features:

  • Ingredients: You will likely be cleaning your boat above water. Therefore, you should get a boat wash that doesn’t contain any dangerous chemicals that could be hazardous to marine life. Most products are labeled as eco-friendly and biodegradable. That means they do not contain ammonia, phosphates, and some are even alcohol-free. These are the safest types of boat soap you should use.
  • Cleaning power: If you need an all-purpose soap for your cleaning and maintenance arsenal, you should get one. However, if you need to get rid of tougher spots, water stains, grime, you will need a powerful formula. Luckily, there are all kinds of products with formulas ranging from daily soaps to heavy-duty ones. Keep in mind that a boat wash isn’t any oxidation or a mildew remover. At most, such a product will get rid of some stains but won’t prevent them from re-appearing.

What is more, these eco-friendly products are not as powerful as their chemical counterparts. Re-applying them a few times might be needed for heavy-duty dirt and stains.

  • A plain formula or with wax: You will notice that in some of our reviews, the cleaning agents are combined with wax. Such products help with eliminating dirt and with enhancing the shine on the treated surfaces. If your boat’s hull and deck are looking dull and you want to bring their glossy look back, this might be the way to go. These boat washes do not remove the existing layers of polish. What they do is leave another protective wax layer on the treated area. But in cases where you need a simple soap to remove grime, you should get the plain soap formula.
  • Application: There are a couple of ways to apply your boat wash, all of which efficient but time-consuming. The three ways to apply the product are with a brush, with a sponge, or with a spray and cloth. One might say that using a spray is faster, however, we disagree. The results can turn up worse, and if your boat is large, it may take even longer. Spraying and wiping are great to do in a smaller area or on the interior of the ship. For cleaning the deck or the hull, you may find it easier to use a brush or a sponge. Both do well at removing stains and tougher grime because you apply more physical effort into it.
  • Scent: As with most cleaning products, boat washes come scented too. There are, of course, unscented products, if you prefer such. On the other hand, you may want your boat to have a pleasant fragrance to replace the fish smell. There are products for that too. Some of the most popular scents are pine cone and citrus.

How Often Should You Clean a Boat?

It is recommended that you clean or at least rinse your craft after each sailing. This rule is more important if you sail in saltwater because the salt causes the hull to fade and acquire scratches faster than freshwater. That being said, you aren’t obligated to use soap every time. Even if you use only water, it would still be helpful. In fact, using soap too often can have a downside, as well. The excessive use of boat wash can break down the wax on your boat.

Yes, some products are a combination of soap and wax, but we suggest that unless your boat needs to be polished a bit, you should use plain soap. Maintaining your boat’s interior and exterior on a daily basis will guarantee that it will survive being subjected to any harsh conditions.

Frequently Asked Questions

Can I Use My Boat Soap to Clean the Inside and Outside of My Boat?

As you see from our reviews above, most if not all marine wash products are suitable for cleaning the interior and exterior of your boat. There are various products with different features. Some marine cleaning products can also be used on other types of vehicles, like RVs, cars, even motorcycles. On the other hand, some are strictly made for boats and can damage the paint on your car.

Do I Have to Buy a Wash and a Wax Combined or Separately?

You can buy them separately. It depends on your budget on how much time you have to work on your boat, but most importantly, it depends on the ship’s condition. Keep in mind that products that combine soap and wax simply leave a glossier finish on the surface. These cannot be used as substitutes for waxing the surface. So, if your boat needs waxing, get soap and wax separately.

Do I Need to Prepare the Surface Before I Use the Soap?

No, you don’t have to do anything before applying the soap. After all, it is a boat wash, and it’s intended to clean grime, dust, stains, or water spots from your craft. You can use a boat wash to prepare a surface for another treatment, like stripping gel coat or waxing.  At most, if the craft is too filthy, you may rinse it first to get rid of loose dirt before you apply the boat wash.

Should I Use a Cloth, a Sponge, or a Brush?

Many newly boat owners stress about how to wash a boat, but it’s simple. You can use whichever you feel will do the best work on your boat. If it’s too grimy and dirty, you may need to use a brush. You should also know that there are different kinds of boat brushes. You can read our detailed posts and reviews on boat cleaning brushes.

Does Any Boat Wash Remove Oxidation?

Unfortunately, no boat wash does, because they are not intended to do so. If your craft has rust stains or suffers from mild or heavy oxidation, you will need a more robust product. To heal your boat from oxidation, you can read more on the subject in our article and boat oxidation remover reviews.
