Product Description

Why Use Gtechniq Marine Synthetic Deck Cleaner?

Synthetic and composite decks are exposed to salt, algae, mold, and mildew buildup, especially on non-skid surfaces where grime collects in textured grooves. Synthetic Deck Cleaner is formulated to break down that buildup without the harsh chemicals that can damage delicate deck materials.

 

The powerful formula lifts dirt and stains while preserving your deck’s texture and finish. It handles stubborn areas effectively, and leaves no harmful chemical residue behind. Safe for all synthetic and composite deck materials, it delivers a thorough clean while keeping surfaces spotless and slip-free.

  • Step 3: Rinse with clean water and repeat if necessary.
  • Step 4: For heavily soiled areas, agitate with a soft bristle brush before rinsing.

Safety Data Sheets

The Gtechniq Difference

At Gtechniq, we formulate products for the conditions you actually face. Synthetic Deck Cleaner was developed because standard surface cleaners struggle with marine environments, where algae, mold, and salt create buildup that household cleaners can’t touch.

 

Our marine lineup goes through real-world testing on actual boats before anything reaches the market. Deck cleaning is a tough job, and the products need to match. We focus on formulas that work without damaging the surfaces they’re meant to protect, giving you effective cleaning power without the trade offs.

Frequently Asked Questions

What surfaces can I use this deck cleaner on?

Synthetic Deck Cleaner is formulated for synthetic and composite deck materials commonly found on boats. It's also safe for non-skid surfaces and textured decking. For wood decks or teak, use a dedicated wood deck cleaner instead.

Will it remove mold and mildew stains?

Yes. The formula is designed to break down mold, mildew, and algae buildup. For heavy mildew stains, let the product dwell for the full 5 minutes and use a soft bristle brush on stubborn areas before rinsing.

Do I need to rinse after application?

Yes. Always rinse thoroughly with clean water after the cleaner has done its work. This removes loosened dirt and grime along with any remaining product, leaving no residue behind.

Can I use this before applying Synthetic Deck Sealant?

Absolutely. Synthetic Deck Cleaner is the ideal prep step before sealing. Clean the deck thoroughly, let it dry completely, then apply Synthetic Deck Sealant for long-lasting protection against UV rays, stains, and water damage.

How often should I clean my synthetic deck?

Frequency depends on use and exposure. Boats in heavy use or stored in humid conditions may need deck cleaning every few weeks. For occasional use, a thorough cleaning at the start and end of season keeps algae and mildew from taking hold.
