Hull Cleaning & Waterline
Stain Removal
Florida's coastal waters leave their mark. Rust streaks, mineral deposits, tannin stains, and waterline scale are inevitable — but they don't have to be permanent. Our mobile hull cleaning service removes every trace and protects your hull from future buildup.
Every Type of Hull Stain in Southwest Florida
Waterline Mineral Deposits
Hard calcium and magnesium scale from Florida's mineral-rich coastal waters. Requires acid-based treatment.
Rust & Iron Stains
Orange-brown streaks from anchor chains, fittings, or marina dock hardware. Treated with oxalic acid compounds.
Tannin & Organic Stains
Dark brown staining from mangrove tannins common in Southwest Florida's inland waterways and canals.
Biological Growth Residue
Algae, barnacle shadows, and biofilm residue on the waterline and topsides after bottom paint application.
7-Step Hull Cleaning Protocol
Every hull cleaning follows a structured protocol designed to remove stains completely without damaging your gelcoat. We work at your dock, marina slip, or boatyard — no haul-out required for topside and waterline work.
On-Site Assessment
We inspect the hull to identify stain type — waterline mineral deposits, rust streaks, tannin stains, or biological growth — and select the appropriate treatment protocol.
Pre-Rinse & Prep
A thorough fresh-water rinse removes loose salt, debris, and surface contamination before chemical treatment begins.
Targeted Chemical Treatment
We apply the appropriate marine-safe chemical treatment based on stain type. Acid-based treatments for mineral and rust stains; enzyme-based for organic growth. Dwell time is monitored carefully.
Mechanical Agitation
Where needed, we use soft-bristle brushes and orbital scrubbers to break up stubborn deposits without scratching the gelcoat surface.
Thorough Rinse & Neutralization
All chemical residue is fully rinsed and neutralized to protect your hull's gelcoat and prevent any surface damage.
Protective Coating Application
We apply a marine-grade polymer sealant to the cleaned waterline area to slow future stain buildup and make the next cleaning easier.
Final Inspection & Photography
Full photo documentation before and after, with written condition notes and maintenance recommendations for your records.

Hull Cleaning FAQ
How often should I have my hull cleaned in Southwest Florida?
In SWFL's warm, mineral-rich coastal waters, waterline stains can develop within 4–8 weeks. We recommend a hull cleaning every 60–90 days for vessels kept in the water, and a full waterline treatment at least twice per year for vessels on lifts or in dry storage.
Will hull cleaning damage my gelcoat?
No — when performed correctly with the right chemicals and technique, hull cleaning is completely safe for gelcoat. We use marine-safe, pH-appropriate treatments and never use abrasive methods that would scratch or dull the surface. Our process is designed to protect your gelcoat, not harm it.
Can you remove heavy rust stains from the waterline?
Yes. Heavy rust staining from anchor chains, dock hardware, or metal fittings responds well to our oxalic acid-based treatment protocol. Extremely heavy or long-standing rust staining may require multiple treatments or a light compound polish after chemical removal.
Do you clean boat bottoms (antifouling paint)?
We specialize in topsides, waterline, and hull above the waterline. For below-the-waterline bottom cleaning (antifouling paint maintenance), we recommend working with a certified marine bottom cleaning service. We are happy to refer you to trusted partners in the SWFL area.
How long does a hull cleaning take?
A standard waterline and hull cleaning takes 2–4 hours depending on vessel size and stain severity. We work at your dock, marina slip, or boatyard — no haul-out required for topside and waterline work.
