Seascour is the boater’s choice for eco-friendly marine descaling.
If you’ve ever faced the hassle of marine scale buildup—barnacles, calcium, lime, or mussels—you know how quickly these issues can sideline your vessel and increase maintenance costs. That’s where Seascour comes in. A game-changer in the marine descaler market, Seascour is the first and only plant-based, organic marine scale remover to earn the U.S. Environmental Protection Agency’s (EPA) Safer Choice certification for outdoor use. It’s powerful, non-toxic, and safe for both your equipment and the environment.
Seascour is being used on merchant vessels, recreational boats, and has undergone testing with the U.S. Navy, Coast Guard, and NOAA research vessels. It’s also winning recognition across the industry—it’s a USDA-certified bio-based product and an IBEX Innovation Award winner.

A New Standard in Marine Maintenance
Traditional descalers often contain harsh chemicals like hydrochloric and phosphoric acid, which can corrode systems and harm marine ecosystems. Seascour does the job without the damage. It effectively removes scale from heat exchangers, refrigeration systems, cooling systems, boilers, desalination units, pumps, and compressors—all without requiring special handling or disposal.
Seascour’s easy onboard application puts maintenance back in your hands. There’s no need for outside technicians or complex scheduling. Just apply, flush, and go—saving yourself time, money, and operational headaches. You’ll also reduce maintenance frequency, extend the life of your equipment, and avoid the corrosion that traditional descalers can cause. That adds up to fewer costly repairs and replacements over time.
One of Seascour’s biggest benefits is its environmental profile. Approved by the EPA for safe outdoor use, it doesn’t contribute to harmful algal blooms like chemical-based descalers. No special disposal procedures are required—it’s as easy on the water as it is on your systems.

Seascour is backed by Hendry Holdings, one of the most respected names in the American maritime industry and the owner of Tampa’s Gulf Marine shipyard. The company is continuing to pursue additional accreditations, including NAVSEA and Green Marine certifications, to further solidify Seascour’s place as the gold standard in sustainable marine maintenance.
From small personal crafts to full-scale commercial fleets, Seascour is the eco-safe descaler boaters have been waiting for. It takes the hassle—and the harm—out of marine maintenance. seascour.com
