Hull & Below Waterline
Professional-grade cleaners that dissolve waterline stains, rust, and hard marine growth below the waterline. Let the chemistry do the work, not your arms.
Keep your boat clean with MA5X biodegradable boat cleaning products, proudly made in the USA for heavy-duty performance with minimal environmental impact. Dissolve waterline stains and rust with our boat hull cleaner, wipe out barnacles without scraping, and pick the right boat soap for the job: an all-in-one wash and wax that leaves UV-resistant protection, or a wash-only concentrate that cleans without stripping your existing wax. Inside the cabin, eliminate musty odors and protect vinyl seats from sun damage. Below deck, degrease the bilge and flush salt from your engine before corrosion sets in. Or see all products ↓.

Marine Wash & Wax is an all-in-one boat soap that cleans and leaves behind a protective, UV-resistant wax finish in a single step. Marine Wash Cleaner is a wash-only boat soap with high-foaming action that lifts salt, grime, and everyday buildup without adding or removing anything. Choose Wash & Wax when you want cleaning plus protection in one pass. Choose Wash Cleaner for routine washes between wax applications.
No. Marine Wash Cleaner is formulated to clean thoroughly while respecting your existing finish, so it will not strip the wax you have already applied. That makes it the right choice for regular maintenance washes on a boat that was recently waxed or detailed. If your finish looks dull and needs fresh protection, wash with Marine Wash & Wax instead.
Yes. Both boat soaps are gentle on automotive paint and clear coats. Marine Wash & Wax adds UV protection and water beading to cars, trucks, RVs, and trailers, while Marine Wash Cleaner gives you a high-foam wash that will not strip existing wax or sealants. Many customers use one soap for everything in the driveway and at the dock.
Hull cleaner is a concentrated formula for routine cleaning of waterline stains, rust, algae, scum, and yellowing on fiberglass, gel coat, lower units, and trailers. Barnacle remover is a stronger concentrate that dissolves barnacles, sea lime, and hard calcium-based growth so you can rinse them away without heavy scrubbing, and it also clears marine growth from seawater cooling systems. Use hull cleaner for regular maintenance and barnacle remover for heavy buildup.
Apply MA5X Boat Hull Cleaner to the stained area, let it dwell for up to 10 minutes, then rinse thoroughly with fresh water. The formula dissolves waterline scum, rust stains, and mineral deposits chemically, so most stains release without aggressive scrubbing, and for routine maintenance you can dilute it 1 part to 4 or 5 parts water. Wear gloves and eye protection, avoid prolonged contact with metals, and rinse surrounding surfaces when finished.
MA5X Barnacle Remover dissolves the calcium deposits that cement barnacles and other marine growth to the hull. Apply the diluted solution, give it about 10 minutes to penetrate, and most growth releases or wipes away without gouging your gelcoat with scrapers. Large, mature colonies may need light agitation, but the goal is to let the chemistry do the work instead of your back.
Yes. In addition to hulls and waterlines, the concentrate is designed to clear marine growth and mineral scale from seawater cooling systems, which helps prevent overheating, pipe blockages, and impeller damage. Circulate the diluted solution through the system according to the label directions, then flush completely with fresh water to restore proper water flow.
Flush after every saltwater outing, and if your boat stays in saltwater, make it a weekly habit even when the boat has not been used. Mix MA5X Salt Remover with fresh water per the label and circulate it through the cooling system. Its built-in anticorrosive additive leaves a light protective film on metal after the salt dissolves, helping slow rust and corrosion between flushes.
MA5X Bilge Cleaner is a heavy-duty citrus degreaser that breaks down the oil, diesel film, grease, and sludge that collect in the lowest part of your boat. Dilute per the label, let normal boat motion circulate the solution, then pump out and dispose of the waste on shore in line with local discharge rules. Never pump oily bilge water overboard. A clean bilge is easier to inspect and a major step toward a fresher smelling boat.
Yes. Because it is a degreaser and odor remover in one, it targets the source of bilge odors, the film of oil and fuel residue coating surfaces below deck, and leaves a fresh citrus scent instead of a harsh chemical smell. For odors that have worked their way into cabin fabrics and surfaces above the bilge, follow up with MA5X Odor Eliminator.
Musty odors usually come from mold and mildew growing in damp, closed-up spaces. Clean hard surfaces first, then mist the cabin with MA5X Odor Eliminator, a ready-to-use spray formulated to quickly remove musty smells along with smoke, mold, and mildew odors. Let treated areas dry with ventilation open, and reduce trapped moisture so the smell does not come back between outings.
No. It neutralizes odors at the source instead of masking them with heavy fragrance; the formula encapsulates and breaks down odor molecules on contact, leaving only a light scent behind. It works on musty smells, smoke, mold, mildew, fish, diesel, and pet odors across most hard and soft cabin surfaces, including upholstery, headliners, and carpet.
MA5X Vinyl Cleaner Spray cleans marine vinyl and adds shine and UV protection in one step. Use it on vinyl seats, cushions, rubber, plastics, chrome, and interior trim to lift dirt, sunscreen, and grime, then leave behind a protectant that helps reduce sun-related fading, drying, and cracking. It comes as a ready-to-use 32 oz spray, so there is nothing to dilute.
Our 5% vinegar cleaner naturally dissolves hard water spots, mineral deposits, and salt residue without harsh chemicals, and it is gentler on you and your surfaces than bleach-based products. Because it is a true multi-purpose cleaner, plenty of customers keep one bottle on the boat and another in the house.
It varies by product and by job, so start with the ratio printed on each label. As examples, Marine Wash & Wax uses just 2 oz per gallon for routine washes, Bilge Cleaner runs about 1:20 for maintenance, and Barnacle Remover mixes 1:4 for heavy fouling. That range is the advantage of concentrate: one bottle covers everything from quick rinses to deep cleans and costs less per wash than ready-to-use products.
It depends on the product, so check each label. The boat soaps clean metals gently, and Salt Remover is formulated for aluminum, stainless, and chrome while leaving an anticorrosive film behind. Acid-based products like Hull Cleaner and Barnacle Remover work fast and should not be left in prolonged contact with metals or sensitive coatings; apply, let them dwell per the label, and rinse thoroughly. Spot-test older or refinished surfaces first.
All Eco Marine products are biodegradable and phosphate-free, and they are designed to minimize environmental impact in both saltwater and freshwater when used as directed. Follow the label instructions and observe local rules on washing and discharge, especially in marinas and protected waters, since regulations vary by location.
For routine washing with biodegradable soap, many marinas allow in-water cleaning, but rules differ, so check with your marina and local regulations first. Heavier jobs like hull cleaning and barnacle removal are best done with the boat hauled out, where runoff can be controlled. Never discharge bilge water or concentrated cleaning solutions directly into the water.
Yes. Most marine products are available in 1-gallon jugs, and we manufacture 55-gallon drums of the same formulas for high-volume users through our Bulk & Wholesale collection. Drums ship via LTL freight or can be picked up at our South Florida facility. If you run a marina, detailing operation, or charter fleet, contact us about wholesale pricing through the MA5X Pro Partner Program.
Yes. Every MA5X product is manufactured in the USA at our South Florida facility. Making our own formulas lets us control quality from raw materials to the finished bottle, and it is why we can offer professional-grade marine chemistry with an eco-minded approach at a fair price.
