When the boat is bought new, it shines and offers a beautiful sight. After a while, however, a lot of dirt accumulates on the boat and the shine is lost. Stubborn dirt often accumulates on the boat, especially during the winter months. With a few tips and tricks, your boat will shine like on the first day and look like new. But when is the best time to clean the boat and what do you have to look out for? All the answers about ideal boat care can be found in the following article.

When is the best time to clean your boat?

At best, you should maintain and clean your boat regularly. Especially before long trips, if your boat was previously on land, a thorough cleaning should be done. As a result, cleaning and conditioning before and after winter is highly important. Before wintering, your boat should also receive a thorough cleaning to prevent damage from the cold and damp. A rough basic cleaning is also recommended after every trip to remove dirt and damage caused during the trip.

What is the best way to clean and maintain your boat?

There are special boat cleaners to get the boat back in shape. You can find out exactly how to clean the individual parts of the boat in the following:

Cleaning a boat - How it works

Teak furniture

Special cleaners are available for teak furniture to remove discolouration, oil, grease and dirt.


The carpet is first swept with a broom to remove coarse dirt. For larger stains, a stain remover can be used, but it must be suitable for the specific material.


To clean the boat upholstery, a brush is first suitable for the coarse dirt. Afterwards, it is best to remove the dirt with a damp cloth as well as warm water and a mild detergent. A special stain remover for upholstered furniture can also be used to remove stubborn stains. However, this should not damage the material. Afterwards, the upholstery must be dried with a cloth, because direct sunlight could bleach the upholstery.

Underwater hull

To clean the underwater hull, you need a high-pressure cleaner. With this, you can completely free the boat from fouling in just a few minutes.

Polishing the boat

After washing, it's time to get down to business and polish the boat. To do this, make sure there is no dirt or oil on the boat. A polish is particularly appropriate if the surface of the boat is dull or matt.

Start with a coarse sanding polish, then finish the topside with a finer polish. For sanding, use a sanding block and coarse sandpaper to remove even larger imperfections and scratches. The choice of grit depends on the size of the damage and scratches as well as the colour of the boat. At best, work in circular motions and change the sandpaper as soon as it is worn out.


Do not leave out any spot on the boat and polish each spot equally. To do this, you can divide the boat into several sections according to a scheme and always work in the same order.

Waxing the boat

To protect the boat from the elements and weathering, a boat wax can also be used.

Advice on environmental compatibility and sustainability in boat care

    1) Use environmentally friendly cleaning products (without bleach and harmful chemicals)

    2) Avoid overuse of detergents

    3) Use water-soluble waxes

    4) Proper disposal of used cleaning agents and waste water

    5) Consider energy efficiency (e.g. energy-saving pumps and fans)

Which cleaning products are most suitable?

Environmentally friendly cleaning products that are biodegradable or natural cleaners such as vinegar, baking soda or citric acid are best. The use of cleaning products also depends on the material of the boat. The cleaning products should be suitable for all types of surfaces and boats. If you then follow the manufacturer's instructions, you will soon get the boat's shine back.

What mistakes should be avoided at all costs when cleaning boats?

When cleaning a boat, there are some mistakes that should be avoided:

Harmful chemicals such as aggressive solvents or bleach can cause damage to the boat and have negative effects if released into the environment. To conserve resources and avoid waste, do not use too much cleaning agent. Coarse cleaning brushes or steel wool can leave scratches on the boat and damage the surface in the long term. Excessive use of water should also be avoided to save resources and energy.

How do you protect your boat from damage in winter?

These tips will keep your boat properly protected in winter:

    1) Covering (waterproof and breathable winter tent or a tarpaulin)

    2) Store in a safe and sheltered place (protection from storms and weather damage)

    3) Air out your boat to prevent damp and mould

    4) Remove all water residue before stowing the boat for the winter (prevent rust and corrosion)

    5) Use a boat paint protectant to protect the boat from UV rays and the elements
