How To Clean A Fiberglass Boat Deck


You take great care to ensure the interior of your boat is
clean, not to mention the obvious sections of your hull that show to the world.
But what about your deck? Is it possible to clean it safely without spending
too much time on back-breaking labor? As it turns out, there’s plenty you can
do—so long as you have the right products in your corner. Here’s how to clean a
fiberglass boat deck the easy way.

Prepping the Deck

It starts with adequate preparation. You’ll want to brush
off all the debris before cleaning it. Here are some tips for adequately
prepping your fiberglass deck without too much strife:

  • Wipe down
    the deck first
    . You can purchase gloves specifically designed for dusting
    and wiping away debris, or, better yet, invest in a push-broom with a
    fiberglass-friendly attachment that makes it easy to handle lots of fiberglass
    real estate at a time. You’ll want to get the debris off the fiberglass before
    you add any cleaning product to it to ensure that you end up with a streak-free
    remainder after you’re done cleaning.
  • Rinse
    down the deck before working with the cleaning material
    . This can jog loose
    any additional debris and make it easier to wipe off any streaks or other
    hard-to-clean areas on the boat deck. One quick note: always let the rinse dry off before you step foot on the fiberglass

Cleaning Your

Once you have the deck adequately prepared, it’s time to
think about how to best approach the actual cleaning. We recommend that you
work with the right materials from the outset. Otherwise, you’ll only make the
process harder on yourself. Here are our suggestions:

  • Boat Cleaner is
    a non-phosphate, environmentally safe formula that’s great for cleaning broad
    areas on your boat. Your fiberglass deck happens to qualify. You can mix this
    solution with water for plenty of extra volume, which is integral for a job
    like this.
  • Release
    Adhesive & Sealant Remover
    . This spray is great for any
    adhesives you’ve been meaning to get off the deck—or any surrounding areas—for
    some time. You’ve likely been putting it off because you’re afraid of doing
    damage to the underlying fiberglass with a scraper. This is the product that
    will help you remove the entire adhesive, if possible, without leaving any

Once you have these two products secured, you’ll want to
formulate your strategy. Typically, boat owners will use something like a
long-handled squeegee to make quick work of it. Make sure that you have solid
footing and that you put safety first, working out at the edges and then backward
to ensure that you have dry footing. But make sure you look before you step!
