Vinyl Mold Removal and Prevention Tips for your Boat
Though advances in marine vinyl production have resulted in the development of mold-resistant materials, boaters are still frequently finding unsightly mildew spots on their seats. The reason for this stubborn mold growth is quite simple. Passengers are often swimsuit or bikini-glad, and 
either covered in sun-tan lotion, or still carrying some residual soap on their skin. As you hit the water and enjoy the warm sun, your passengers will sweat, and all of their exposed skin will leave this oily residue wherever it touches your marine vinyl.
To give you the best possible start into maintaining your boats vinyl interior, Midwest Fabrics provides an effective vinyl cleaner, which you can find on our online store.
These grimy leftovers combine with the moisture in the air to create a perfect environment for mold growth. While the marine vinyl itself may be sealed off and resistant to subsurface growth, there is nothing to stop mold from clinging to its exterior. Many people try to cover their seats to offset the growth of mold, but are frustrated to find that moisture can still penetrate through these covers. The only option is to maintain your vinyl with regular cleaning. Fortunately, this process is relatively easy.
How to clean mold off of marine vinyl surfaces
- Prevention is key. The longer you neglect to clean any moldy spots, the tough it will be once you have finally mustered up the motivation to try. Mold will spread and thicken if left unattended to, so act fast or be ready to bring some elbow grease with you.
- Find the right product. There are many mold-cleaning products out there, each with their own pros and cons. Cleaners that use bleach are very effective and affordable, but can corrode your marine vinyl over time, especially when exposed to sunlight over long periods. If you choose a bleach cleaner, be sure to use lots of water, and rinse thoroughly. A line of special marine mold-cleaning products exist containing ultraviolet-blocking ingredients, though they are typically more expensive.
- Don’t rush the process. Though you likely have little interest in drawing out your cleaning chores, you need to give your bleach or cleaning formula a chance to break down the mold. The bigger the problem, the longer you should let the solution sit after application.
- Take it easy. Once the solution has set for an appropriate amount of time, scrub it off of your vinyl surfaces using a soft-bristled toothbrush. Brush lightly to avoid causing any damage, but be sure to target stitching where grime often accumulates.
- Rinse well. Neglecting to give your vinyl a good rinse is a big problem. Not only can this result in corrosion of your vinyl, but residual soap and mold spores can start to grow back right where you left them.
- Buff up. Buffing your marine vinyl after cleaning is an important step that does more than leave a beautiful finish. Buff with a clean towel to ensure that all moisture is removed, so that mold has nowhere to hide.
