Boat Cleaner Buying Guide

Replacing the vinyl of your boat upholstery and seats can be a fairly expensive repair. The lack of maintenance, direct sunlight and general wear and tear can destroy the boat interior over time but by using a simple boat cleaner, you can extend the lifespan fairly easily. There are various boat cleaning products on the market that are suited to the marine environment and we highly recommend the products mentioned above.

To help you make an informed buying decision, we have produced the below-buying cleaner to help improve your boat cleaning knowledge.

How To Clean Your Boat Seats

Boat seats can be the worst to clean due to the tiny areas where dirt or debris can collect. However, as you will be sitting on them for long periods of time, it’s important that they are clean and free of mildew because these will transfer onto your clothes. In order to clean your boat seats, we recommend the following tips:

  1. Use a vacuum or brush to remove loose debris or dirt.
  2. Pick a suitable boat cleaner.
  3. Spray the cleaner into the seats and allow them to settle.
  4. Use a soft brush to rub the formula into the worst affected areas.
  5. Wipe down with a slightly damp but clean cloth.
  6. Remove wet residue with a dry cloth to finish.

Cleaning boat seats that are completely covered in dirt can be very rewarding. White is a desirable color for boat upholstery but they do become dirty very quickly, therefore regular usage of a boat seat cleaner is highly recommended. As you can see below, the seats were in a bad way before a cleaner was used.

Cleaning Boat Vinyl

The boat vinyl that you see onboard most boats is designed to resist the buildup of mold and mildew. However, due to the tough marine environment, it can not always withstand the heavy buildup and overtime, they can become coated with dirt.

Wherever there is water, the buildup of moisture inside the boat is always going to produce mold and mildew on the vinyl. Luckily, there are many boat cleaning products available that target mold and mildew with ease. However, not all the cleaning products will be saved and it’s important that you check the formula beforehand.

For example, some bleach-based products are known to completely ruin the stitching of the vinyl, which can cause the vinyl to come apart. The damaging effects of bleach and UV rays combined can cause even further issues with vinyl too. It can cause the threads that bind the vinyl materials such as seats or cushions to weaken, which can reduce the lifespan quite significantly.

If you are choosing alternative boat cleaner products, we strongly recommend checking the formula.

Preventive Maintenance

In order to avoid hours of cleaning the boat interior, taking time to prevent dirt from building up in the first place will help. Some of the worst molds come when boat owners put their boats away for storage during the winter. Before doing this, it’s important that the boat is left to “air out” and completely dry inside. Putting a cover straight on the boat does not allow the moisture to escape thus causing mold.

It is near enough impossible to avoid dirt and debris forming onboard your boat, which is fine. However, leaving the dirt on vinyl or other upholstery whilst in direct sunlight can cause it to harden. This will result in a lot more scrubbing and boat cleaner being used. We highly recommend having a spray bottle on board at all times so that you can remove the dirt quickly.

Bottle Sizes

Boat cleaner is not the cheapest of cleaning products and the small 16 oz bottles that most come in will not last long. We highly recommend investing in a 128 oz bottle and a spray bottle at the same time. This will allow you to keep refilling the spray bottle and save a considerable amount of money over time.


Avoiding dirt and debris can be hard and it is made even harder with white boat interior. Investing in a quality boat cleaner can make a world of difference when it comes time to removing mold, mildew and other tough stains.

All of our recommendations are suitable to be used onboard a boat and a range of other surfaces. If you are yet to use a true boat cleaner, then it will completely transform the ease of cleaning vinyl and other upholstery.
