Our Process

Restoring the SHINE of your boat
Step 1: Initial Wash
A decontamination wash is essential to start correcting the gelcoat by scrubbing/washing the boat to remove old waxes and dirt to prepare the surface for restoration.
Step 2: Oxidation Removal
If the boat has heavy oxidation, it will be wet sanded as needed, particularly if it leaves a chalky residue at first touch. This will be followed by compounding to reveal the glossy gelcoat underneath.
Step 3: Polishing
Polishing will eliminate any scratches or swirls left from compounding and provide a protective layer.
Step 4: Protection
Once compounded and polished, GTHN will apply a coat of wax, polymer sealant or ceramic coating to protect the finish.
Step 5: Maintenance
Routine maintenance is essential for preserving the gelcoat. Regularly washing the boat and reapplying protective sealants will help keep it looking its best.
Stoney Creek Mobile Interior Cleaning
Mobile interior cleaning for boats in Stoney Creek brings professional restoration directly to your vessel, whether it's moored at a local marina or stored on your property. GTHN Boat Polishing specializes in thorough interior detailing that removes salt residue, mildew, oxidation, and embedded grime while protecting your boat's finishes and upholstery. This guide walks you through what to expect during the process so you understand each stage and can prepare your vessel properly.
Stoney Creek boat owners-many of whom maintain sailboats and powerboats in the Golden Horseshoe region-value vessels that perform well and hold their resale value. A clean, well-maintained interior protects that investment and makes time on the water more enjoyable. The steps below reflect industry-standard marine detailing methodology, ensuring your boat receives the same multi-stage correction techniques used by professional restoration specialists.
Step 1: Initial Assessment and Preparation
The first phase involves a thorough walkthrough of your boat's interior to identify problem areas, material types, and specific cleaning requirements. GTHN Boat Polishing technicians will note salt deposits on cabinetry, staining on upholstery, mildew growth in enclosed spaces, and oxidation on metal fixtures. This assessment determines which cleaning agents, tools, and techniques will be most effective without damaging your boat's finishes.
Before work begins, remove personal items, loose gear, and any equipment that might obstruct access to surfaces. Open all hatches, cabin doors, and storage compartments. If your boat is moored in Stoney Creek or nearby marinas, ensure there is adequate ventilation-this allows moisture to escape during and after cleaning and reduces the risk of mildew returning. Provide access to fresh water and power if required by the service provider.
Step 2: Decontamination and Pre-Wash
Professional interior cleaning begins with a decontamination wash to remove loose salt, dust, and airborne contaminants. Technicians use low-pressure fresh water and mild surfactants to rinse down all surfaces without saturating wood, upholstery, or electrical systems. This pre-wash phase is critical because it prevents contaminants from being dragged across delicate finishes during the detailed cleaning stages.
Special attention goes to ventilation areas, cabin soles (the interior floor), and overhead surfaces where salt spray accumulates. The decontamination stage typically takes 30-45 minutes depending on your boat's size and condition. For boats stored in Stoney Creek's variable climate, this step removes environmental buildup and prepares surfaces to respond properly to targeted cleaning treatments in the next phase.
Step 3: Targeted Surface Cleaning and Oxidation Removal
Once decontamination is complete, GTHN Boat Polishing applies specialized cleaning formulations to specific surfaces based on material type. Fiberglass cabinetry receives marine-grade cleaners designed to remove oxidation and restore clarity without etching. Upholstered seating and curtains are cleaned with pH-balanced solutions that lift mildew, salt staining, and embedded grime while preserving fabric integrity. Metal fixtures-stainless steel, chrome, and aluminum-receive corrosion removers and protective treatments to prevent future oxidation.
This stage uses hand application, soft-bristle brushes, and microfiber cloths to ensure precision on delicate surfaces. For heavily oxidized areas, technicians may employ light abrasive polishing compounds applied with rotary tools at controlled speeds. The goal is to restore the original finish and color without aggressive material removal. Thorough rinsing follows each treatment to remove all residue and prevent product buildup.
Step 4: Final Inspection, Protection, and Ventilation
The final phase includes a complete walkthrough to verify all surfaces meet quality standards. Technicians inspect for missed spots, streaking, or residue and address any touch-up work. Once surfaces are verified clean, protective treatments are applied where appropriate-UV-protective coatings on exposed fiberglass, fabric protectants on upholstery, and corrosion inhibitors on metal. These products extend the cleanliness and condition of your interior between services.
Proper ventilation is essential in the closing stage. GTHN Boat Polishing ensures all interior spaces are thoroughly dried using air circulation and, where necessary, portable dehumidification. Leave cabin doors and hatches open for several hours after the service completes to allow residual moisture to escape. This practice prevents mildew regrowth and ensures your boat's interior remains fresh and protected.

Frequently Asked Questions
How long does Stoney Creek mobile interior cleaning typically take?
Most interior cleaning services take between 4 to 8 hours depending on your boat's size, the level of soiling, and the scope of work. Smaller vessels or light cleaning may finish in 3-4 hours, while larger powerboats or heavily oxidized interiors can require a full day or more. GTHN Boat Polishing will provide a time estimate after the initial assessment.
What materials can be safely cleaned during interior detailing?
Professional interior cleaning handles fiberglass cabinetry, stainless steel and chrome fixtures, vinyl upholstery, fabric curtains, teak and other wood finishes, vinyl flooring, and painted surfaces. Specialized cleaning agents and techniques are matched to each material to avoid damage. Always inform your technician about any custom finishes, rare wood types, or sensitive materials before work begins.
Will professional cleaning prevent mildew from returning to my boat's interior?
Thorough cleaning removes existing mildew spores and salt residue that feeds mildew growth, but prevention depends on ongoing ventilation and moisture control. After professional cleaning, keep cabin doors and hatches open when the boat is not in use, use dehumidifiers in enclosed spaces, and ensure proper air circulation. These practices combined with regular maintenance extend the time between deep cleanings.
Can oxidation be fully removed from gelcoat cabinetry during interior cleaning?
Yes. GTHN Boat Polishing uses multi-stage correction techniques and marine-grade oxidation removers to restore clarity and color to oxidized fiberglass interiors. However, severe oxidation that has etched the surface may require light polishing or, in extreme cases, professional restoration. An initial assessment determines what is achievable for your specific boat.
Is there a mobile interior cleaning service available in Stoney Creek right now?
GTHN Boat Polishing provides mobile interior cleaning throughout Stoney Creek and the surrounding Golden Horseshoe region, including Hamilton, Burlington, Niagara, and the Greater Toronto Area. They bring professional equipment and trained technicians directly to your marina, dock, or storage location. Contact them to confirm availability for your boat.
What should I do to prepare my boat before the cleaning crew arrives?
Remove personal items and loose gear, open all cabin doors, hatches, and storage compartments for access, and ensure adequate ventilation. If possible, provide access to fresh water and power if required. Clear deck space near entry points so technicians can safely move equipment and materials on and off your boat.
How often should I have my boat's interior professionally cleaned?
For boats in regular use, professional interior cleaning once or twice per season is ideal. Salt exposure, mildew growth, and oxidation accelerate in the Golden Horseshoe region's climate. Light maintenance washes between professional cleanings help extend interior condition. Your technician can recommend a schedule based on your boat's mooring location and usage patterns.
