Zing Cleaners: Marine-Grade Fiberglass & General Purpose Cleaning

When it comes to keeping fiberglass surfaces pristine in demanding marine environments, few names carry the weight that Zing Cleaners does. Manufactured in Chicago, Illinois by Nyco® Products Company — a cleaning chemistry innovator with roots going back to 1920 — Zing has spent decades earning the trust of professional marinas, boat detailers, and serious boat owners who refuse to settle for anything less than a like-new finish.

Zing's place in the Fiberglass & General Purpose Cleaners category is built on a straightforward philosophy: professional-strength cleaning that is safe for the surfaces it touches. Their flagship Professional Boat Hull Cleaner is a heavy-duty formulation that easily and quickly removes the toughest build-ups on fiberglass, painted wood, and steel hulls — in both fresh and salt water. Whether you're tackling waterline scum, algae staining, lime deposits, or the stubborn residue left behind by zebra mussels and barnacles, Zing is engineered to cut through it all without compromising the integrity of your fiberglass or gel coat.

Two Lines, One Standard of Clean

Zing offers two distinct product lines that address different priorities for fiberglass and general-purpose boat cleaning:

• Zing Professional Line: Maximum cleaning power for the heaviest marine soils. The Professional Boat Hull Cleaner is the original formula — the choice of marinas and boat cleaning professionals for seasonal cleaning and winterizing alike. It can be applied at full strength for heavy staining or diluted 1:1 with water for lighter maintenance work, giving users flexible control over cleaning intensity.
• Zing Marine Safe Line: A more environmentally conscious option that uses advanced cleaning technology with ingredients identified by the EPA for direct release. Marine Safe products are phosphate-free, readily biodegradable, and formulated to remove tough marine soils quickly while being gentler on the surrounding aquatic environment. The Marine Safe All-Purpose Boat Cleaner extends this performance to interior surfaces like vinyl, windows, and countertops — a true general-purpose solution.

Why Fiberglass Demands the Right Cleaner

Fiberglass and gel-coat surfaces are durable, but they are not impervious. Harsh or improperly formulated cleaners can etch, dull, or permanently damage the surface oxidation layer that gives a fiberglass hull its gloss. Zing's formulas are specifically designed to be safe on fiberglass and painted surfaces when used as directed — a distinction that matters enormously for long-term hull condition. The non-fuming, VOC-free character of several Zing products also makes them practical for use in enclosed marina areas and boat storage facilities.

For boat owners and detailers looking for a cleaner that bridges professional-grade results with responsible chemistry, Zing Cleaners represents one of the most well-established choices in the marine fiberglass cleaning category.
