Best Boat Seat Cleaners: Top Tips For Pristine Seats

Boat seats are made from marine-grade vinyl, chosen for its strength and resistance to moisture and humidity. However, vinyl can only withstand so much, and without regular care, boat seats will accumulate dirt and mildew, leading to damage over time. To keep boat seats in good condition, it's important to establish a regular cleaning routine and protect the seats from harmful UV rays.

When cleaning boat seats, it's best to use a gentle soap and freshwater, rinsing and cleaning the seats as often as possible to prevent mould and mildew from growing. While there are many products available for cleaning and protecting boat seats, it's important to avoid using harsh chemicals, such as bleach, which can damage the vinyl and stitching.

Regular cleaning and maintenance

Boat seats are made from marine-grade vinyl, which is highly resistant to moisture and humidity. However, without regular care, they will accumulate dirt and mildew, which can cause damage over time. To protect your boat seats, you should clean them periodically and shield them from harmful UV rays.

Routine Cleanings

To extend the life of your seats, create a regular cleaning schedule. How often you clean will depend on how often you use your boat and how dirty it gets. If you notice any visible grime, it’s time to scrub!

Wipe Down and Clean Up Immediately

Make routine maintenance a part of your regular boating experience. After each trip, wipe down your seats and clean up any spills immediately to prevent build-up. Keep cleaning supplies on board and use a boat cover when the boat is not in use to protect against tree sap.

Remove Dust and Dirt

Before introducing any cleaning products, vacuum up any loose dust and dirt particles, including under seat covers, between joints, and in crevices.

Clean with a Marine-Grade Vinyl Cleaner

Work in sections to prevent the cleaner from drying out on the surface. Spray the cleaner onto the seat, allow it to sit for a minute, then gently brush the seat in a circular motion. Use a clean, damp cloth to wipe away the grime and a toothbrush to get into the creases. Rinse with a wet cloth to remove any remaining traces of cleaner, then wipe the surface dry with a clean towel.

Stains and Mildew Issues

Stains and mildew often won’t come out with standard cleaners and require special treatment. Try a Magic Eraser by gently scrubbing the surface with a dampened pad, then wipe the area with a clean, damp cloth.

For mildew stains, use a mildew stain remover for marine vinyl. Spray the product onto the stain, let it sit, then gently brush and wipe the surface with a clean, damp cloth. Finish by drying the surface with a clean towel.

Protect from UV Rays

Install a bimini top to keep the sun off your seats and provide shade for passengers. Also, use a UV protectant by spraying it onto a clean microfiber cloth and rubbing it into the vinyl in gentle, circular motions. Buff any excess product with another clean cloth. Reapply the UV protectant every month or so, depending on how often you use your boat.

Using the right products

Boat seats are usually made from marine-grade vinyl, which is highly resistant to moisture and humidity. However, vinyl can only withstand so much before it starts to break down, so it's important to use the right products to clean and protect your boat seats.

Marine-grade vinyl cleaner

It's important to use a cleaner that is specifically designed for marine-grade vinyl. These cleaners are typically gentle and won't scrub or chemically burn away the important anti-microbial, anti-fungal, and anti-stain barriers on your seats.

When cleaning your boat seats with a marine vinyl cleaner, work in sections to prevent the cleaner from drying out on the surface. Spray the cleaner onto the seat and let it sit for a minute, then gently brush the seat in a circular motion. Use a clean, damp cloth to wipe away the grime, and a toothbrush to get into any crevices. Finally, wipe the surface dry with a clean towel, making sure to wipe up any standing water in the cracks.

Mildew stain remover

If you're dealing with mildew stains, you may need to use a stronger product. However, avoid using bleach, as this can deteriorate the stitching on your seats and cause the colours to fade. Instead, opt for a mildew stain remover designed for marine vinyl. Apply the product to the stain and let it sit for a minute, then gently brush and wipe the surface with a clean, damp cloth. Finish by drying the surface with a clean towel.

UV protectant

To protect your boat seats from UV damage, you can use a UV protectant spray. Simply spray the product onto a clean microfiber cloth and rub it into the vinyl using gentle, circular motions. Then, buff any excess product with another clean cloth. Reapply the UV protectant every month or so, depending on how often you use your boat.

Repair kit

Accidents happen, and if your boat seat gets torn or punctured, it's important to repair it as soon as possible to prevent water from getting into the seat and causing mildew problems. Purchase a vinyl repair kit that includes a base compound that matches the colour of your seats. Start by applying the repair compound with the included applicator, then spread it over the damaged area with a plastic knife. Let the compound cure, then gently smooth the repair with 600-grit sandpaper. Finish by applying a coat of vinyl conditioner.

Removing mildew and mould

Mildew and mould are common issues for boat seats, which are often made of vinyl—a material that is susceptible to mildew. To remove mildew and mould from boat seats, follow these steps:

Prepare the Cleaning Solution

If using a commercial mildew stain remover, ensure it is bleach-free, as bleach can damage vinyl. Follow the manufacturer's instructions for mixing and usage. If making a DIY solution, mix one part white vinegar with one part water in a bucket, or use a mixture of equal parts water and hydrogen peroxide (3% solution). You can also add a few drops of dish soap for stubborn stains. Before applying to the whole seat, test the solution on a small, inconspicuous area.

Apply the Cleaning Solution

Dip a soft-bristle brush or a sponge into the cleaning solution and gently scrub the mildewed areas in a circular motion. Avoid applying too much pressure to prevent damage to the upholstery. Let the solution sit for a few minutes to penetrate and loosen the mildew, then scrub once more.

Rinse and Dry

Use a water hose or clean water and a sponge to thoroughly rinse the boat seats, ensuring all traces of the cleaning solution are removed. Then, use a clean, dry microfiber or soft cloth to wipe down and completely dry the boat seats. Proper drying will prevent mildew from returning.

Repeat if Necessary

Heavy mildew buildup may not come off on the first attempt, so you may need to repeat the process several times. Even after repeating, some stains may remain. In this case, you can try using a magic eraser sponge, which is designed to tackle tough stains. However, be careful not to scrub too hard, as this can damage the vinyl.

Prevent Future Mildew Growth

To prevent mildew from returning, store your boat in a dry and well-ventilated area when not in use. Use mildew-resistant seat covers or treat the seats with a mildew-resistant spray. Regular maintenance and cleaning are key to preventing mildew growth. Wipe down your seats after each use and keep the boat covered when not in use, ensuring the cover has a vent cap to allow for air circulation.

Protecting against UV damage

The sun's ultraviolet rays can cause significant damage to boat seats over time, leading to fading, cracking, and peeling. Therefore, it is essential to take proactive measures to protect your boat seats from UV damage. Here are some detailed instructions to help you safeguard your boat seats:

Use a Boat Cover

One of the most effective ways to protect your boat seats from UV damage is to keep them covered when not in use. The sun can slowly cook the seats, causing irreversible damage. By covering them, you create a barrier that blocks the sun's harmful rays. If you don't have access to a garage or shed, consider using a mooring cover or individual seat covers. Most boating supply stores sell seat covers at a reasonable price.

Install a Bimini Top

If you want to enjoy your boat while also protecting your seats from the sun, consider installing a Bimini top. This not only provides shade for you and your passengers but also shields a large portion of your seats from direct sunlight. It's a win-win situation, as you get to enjoy your boat and protect your seats simultaneously.

Apply a UV Protectant

To enhance the UV protection of your boat seats, use a UV protectant designed specifically for vinyl boat upholstery. These products create a wax-like film that conditions the seats and acts as an additional layer of defence against the sun. Spray the protectant onto a clean microfiber cloth and gently rub it into the vinyl using circular motions. Then, use another clean cloth to buff away any excess product. Remember to reapply the UV protectant every month or so, depending on your boat's usage frequency.

Clean and Maintain Regularly

Regular cleaning and maintenance of your boat seats are crucial to protecting them from UV damage. Dirt, grime, and spills can attract sunlight and accelerate the deterioration process. Therefore, it is essential to wipe down your seats after each use and conduct more thorough cleanings periodically. When cleaning, use a marine-grade vinyl cleaner or a mild solution of dish soap and warm water. Avoid harsh chemicals and generic household cleaners, as they can damage the vinyl.

Keep Seats Dry

In addition to cleaning, ensure that your boat seats are dry before covering or storing them. Moisture trapped inside the vinyl can accelerate UV damage and promote the growth of mould and mildew. After cleaning, wipe down the seats with a dry towel and allow them to air dry completely before covering them.

Choose the Right Vinyl

When purchasing boat seats, opt for those made with marine-grade vinyl, specifically designed to withstand the harsh conditions that boats encounter. Within this category, there are different types, such as perforated or fabric-like vinyl. Check with the manufacturer to ensure you select the most suitable type for your boat and to inquire about any special care instructions.

Repairing damage

No matter how careful you are, accidents are bound to happen. A tool falling on the seat, a fishing hook catching on the upholstery, or a bird dropping something on it from above—there are many ways that boat seats can get damaged.

The key to preventing further damage is to act fast. You'll want to repair rips or holes as soon as possible so that water doesn't get into the seat and create a mildew problem. It's much cheaper to quickly repair a tear than to end up replacing a seat because it became infested with mould. Here's how to do it:

• Purchase a quality vinyl repair kit that includes a base compound that matches the colour of your seats.
• Start with a clean, dry surface.
• The kit will contain a special applicator. Apply the repair compound with the applicator and then spread it over the damaged area with a plastic knife.
• Let the compound cure.
• Gently smooth the repair with 600-grit sandpaper.
• If your repair kit doesn’t come with a base compound in the colour of your seats, you can use a spray paint specifically designed for vinyl to match the original colour.
• Finish by applying a coat of vinyl conditioner.

Be sure to use a repair kit that’s specifically made for marine vinyl. You can also get replacement boat seat vinyl by the yard, or have your seat professionally repaired if you aren’t comfortable doing it yourself. If your seats are significantly damaged, especially if mould has taken up residence inside, you may need to replace them.
