Marine Vinyl Care Tips & Tricks

Marine-grade vinyl is wonderfully durable and is designed to withstand harsh marine environments. However, it does need regular and proper care for a long life. We will first talk about both regular marine vinyl cleaning jobs as well as situations where maybe the task was procrastinated a bit too long. Then, we will talk about a couple of things not to do. Finally, we’ll share some of the most popular vinyl care products among the PartsVu community.

But first, why is it so important to care for your boat’s vinyl? Of course, you want your boat to be as attractive and stain free for as long as possible – seats and other vinyl blacked from mold and mildew aren't pretty. Also, over time, UV rays cause vinyl to fade, crack, and peel.

Regular Marine Vinyl Cleaning

We always advise regular cleaning and protection of your boat’s vinyl. Your seating and other vinyl surfaces will last longer and look nice, much longer. While it is sometimes tempting to procrastinate these jobs, don’t. Always follow the steps on the vinyl cleaning product you are using, but the following is the basic procedure:

• Apply cleaner one seat or section at a time to keep cleaning products from drying on the vinyl surface.
• Spray your cleaner onto the seat and allow it to sit for about one minute.
• Gently brush the seat in a circular motion. The cleaner should be doing most of the work for you.
• Use a clean, damp cloth to wipe away the grime as it loosens from the surface.
• If you have trouble getting down into the creases, use an old toothbrush.
• Wet and wring out another cloth and wipe the surface again to remove any remaining traces of cleaner.
• Wipe the surface dry with a clean towel.

Stains – Mold, Mildew, & Other Stains

A Magic Eraser type of product is often very effective for stains that have developed over time. Wet one of the pads and gently scrub your seat surface. When you’re finished, wipe the area with a clean, damp cloth.

You will likely need something a bit more powerful for mold and mildew, but don’t use bleach. The safest way to clean your boat’s vinyl is with a product designed for marine vinyl. We have recommended some products below, and each product will have its own set of instructions, but the following is the general approach:

• Tackle one seat or section at a time to keep the cleaning product from drying on the vinyl surface.
• Spray the mildew stain remover onto the stain and allow it to sit for about one minute.
• Gently brush the stain with circular motions.
• Wipe the surface with a clean, damp cloth to remove cleaner.
• Dry the surface with a clean towel.

While not every stain will come out, you should see a considerable improvement

Apply UV Protection to Marine Vinyl

As mentioned above, UV rays cause vinyl to fade, crack, and peel over time–you, of course, want to avoid this. Covering your boat when it's not in use helps a lot, but your boat's vinyl is exposed to UV rays for many hours when the boat is in use. Follow the instructions for the specific vinyl protectant you will be using, but the following are the basic steps:

• Make sure the vinyl surface you are protecting is clean and dry.
• Spray the product onto a clean cloth.
• Using gentle, circular motions, rub the product into the vinyl.
• With another clean cloth, wipe off excess product.

What to Do If Your Boat’s Vinyl Is Damaged

While marine vinyl is very strong, holes, rips, cracks, and tears can happen. To keep water and salt out of the inside of your upholstery, replace damaged vinyl as soon as possible. A vinyl repair kit may be in order if the damage is relatively small. Or, you might have to consider investing in a professional to repair the damage.

What Should You Avoid?

Tree Sap

Tree sap is especially notorious for causing damage to boat seats when the boat is parked. Once the sap gets on the seats, the sun bakes the sap in, making it extremely difficult to remove. The first step for avoiding sap-stained seats is to avoid docking your boat under a “sappy” tree. But, if any sap gets on your seats, clean them immediately. Covering your boat when it’s not in use goes a long way toward preventing tree sap damage.

Bleach

It is tempting to use bleach to clean your boat’s vinyl, especially if you have delayed the job too long, and you are contending with mold and mildew stains.

Unfortunately, bleach deteriorates the stitching on marine vinyl. The detrimental effects are even more noticeable when you combine bleach and UV rays. Mixing bleach and sunlight will cause the threads that bind vinyl seat cushions to weaken and eventually disintegrate. Therefore, we recommend using a mixture of bleach and water exclusively for smaller mold jobs or as a ­last-ditch effort before reupholstering.
