Why Use Gtechniq Marine Glass Cleaner?

This glass cleaner was built for the marine environment, where salt spray, hard water spots, and grime build up fast. We stripped out everything that causes smearing, including fragrances and cheap solvents, leaving only what actually works.

The result is a streak-free glass cleaner that handles boat windows, windshields, and mirrors without the elbow grease most window cleaners require. An anti-static charge helps repel dust after cleaning, keeping your glass surfaces cleaner between washes. Spray it on a microfiber towel, wipe, and you’re left with crystal-clear views.

Simple steps to help you get the best results

  • Shake well before use
  • Use out of direct sunlight
  • Spray directly onto an MF1 ZeroR Microfibre Buff Cloth and wipe the glass
  • Remove any residue with another clean MF1
  • Store in a cool, dry place
  • Use within 12 months of opening

Safety Data Sheets

The Gtechniq Difference

At Gtechniq, we build products that solve real problems. Our Marine Glass Cleaner exists because we know boat owners face conditions that standard window cleaners can’t handle. Salt residue, mineral deposits, and constant exposure to the elements demand something tougher.

Every product in our marine lineup was developed through extensive field testing on actual vessels. The marine industry presents unique challenges for prep and maintenance, and our solutions reflect that. We make solutions that keep your trips safe and smooth no matter the conditions.

Frequently Asked Questions

What makes this better than a regular window cleaner?

Standard glass cleaners contain fragrances, dyes, and cheap solvents that leave streaks and residue. Our formula eliminates those ingredients entirely, focusing only on cleaning power and a streak-free finish. The anti-static effect also keeps dust from settling back onto the surface.

Can I use this on plexiglass and polycarbonate?

This product is formulated specifically for glass surfaces. For plexiglass, polycarbonate, and other plastic windshields, we recommend our Glass & Plexiglass Coat or Glass Polish, which are designed to clean without scratching softer materials.

Will it remove salt spray and hard water spots?

Glass Cleaner handles everyday salt residue, fingerprints, and grime with ease. For stubborn hard water spots or mineral buildup that has etched into the glass surface, use our Water Spot Remover first, then follow up with Glass Cleaner to keep your glass in tip-top shape.

How do I avoid streaks when cleaning boat windows?

Spray the cleaner onto a microfiber towel rather than directly onto the glass. We recommend you wipe in a single direction, then buff with a second clean microfiber towel. Always work out of direct sunlight, as heat can cause the cleaner to evaporate too quickly and can leave marks.

Is this safe to use around electronic screens?

We recommend keeping this product away from electronic screens and displays. For instrument panels and touchscreens, use a dedicated electronics cleaner to avoid any potential damage.
