So you want to buy a new boat but you don't know what boat maintenance entails. Welcome to the NUVA Yachts blog, here we will briefly and concisely explain what to do to take care of your boat and tips to avoid common problems.
How to clean the exterior of a yacht or boat
Let's start with the basics. You're probably interested in knowing How to Clean the Exterior of a Yacht or Boat because you want it to look aesthetically impeccable, however, this step is also essential to maintain the optimal functioning of your boat.
Essentially, cleaning the exterior of a boat helps preserve its appearance, prevent the spread of invasive species, protect the structure's finish, prevent corrosion, and—something you'll surely love—reduce fuel costs.
Whether you have an outboard boat or another type of vessel, here are some cleaning tips for different materials:
- Fiberglass: Use waxes designed to protect the gel coat and wash with specific soaps.
- Canvas: Clean with a light brush, mild soap and fresh water, avoiding ammonia-based products for PVC.
- Upholstery: Clean regularly with mild soapy water and be sure to store properly between outings.
- Carpentry: For wood components, such as teak, use mild cleaners and brushes to keep it in optimal condition.
What to avoid when cleaning the exterior of a boat?
- Abrasive brushes: Don't use abrasive brushes or sponges that can scratch or damage the surface of your boat. Opt for soft brushes or sponges specifically designed for boat cleaning.
- Ammonia-based products: Avoid using cleaning products containing ammonia, as it can damage certain boat materials, such as clear PVC on the windows.
- Common household detergents: Do not use conventional household detergents, as they may contain ingredients that are harmful to the aquatic environment. Instead, use detergents specifically designed for boats.
- Excessive water pressure: Do not use high pressure water jets directly on sensitive areas or joints of the boat, as this may damage the paint, gaskets or seals.
Store your boat in the right space
Protecting your boat from the elements is essential to extend its life . Storage options include outdoors with retractable, indoors, or in the water. Storing outdoors requires a proper cover or retractable cover to protect it.
Indoor storage offers maximum protection, while on-water storage may be practical for slightly larger boats.

- Replacing cracked hoses.
- Lubrication of spark plug holes.
- Replacing fuel filters.
- Filling the tank and adding antibacterial stabilizers.
- Disconnecting and proper storage of the battery.
- Removal of food, carpets and electronic devices.
