Description
STARKE VENOM — WATER SPOT & STRIP WASH SPECIALIST
Three jobs. One bottle. And the one line every boat owner with a ceramic coating needs to hear before they do anything else.
Before you decide your ceramic coating has failed — do a strip wash with Venom. Nine times out of ten the coating is fine. It's contaminated. Environmental fallout, salt residue, and mineral deposits build up on top of your coating over time and suppress its hydrophobic performance. The water stops beading and you assume the coating is gone. It isn't. It's buried. Venom is the liquid clay bar that pulls that contamination layer off the coating surface without touching the chemistry underneath.
The acidic gel formula (pH ~3.4) is what makes Venom uniquely effective in the marine environment. Unlike low-viscosity liquids that run off vertical hull surfaces immediately, Venom's gel formula clings — giving the chemistry time to work on the waterline, the outrigger hardware, and the hull sides without constant reapplication. Wear chemical-resistant gloves and eye protection, rinse thoroughly, and test aluminum, anodized surfaces and tinted glass first.
Three distinct uses. Monthly strip wash on ceramic-coated boats — the Venom and Replenish sequence is the maintenance cycle that converts a 12-month coating into an 18-month coating. Water spots on gelcoat, glass, and stainless steel — mineral deposits that soap cannot touch respond to Venom's chelating chemistry. Rust staining from anchor chain contact, dock hardware, or iron-bearing water — the same chemistry that dissolves mineral deposits lifts iron oxide contamination cleanly.
One caution worth stating clearly: keep Venom away from MFD screens, chart plotters, and electronics displays. The chemistry will permanently strip the UV-protective coating on those surfaces.
Available in 16 oz. and 128 oz.
