$371.00

MA5X Boat Hull Cleaner in the 55 Gallon Drum format is designed for marinas, boatyards, and fleet service yards that need consistent hull stain removal at scale. The same Eco Marine concentrate used in our 32 oz and 1 gallon sizes is supplied here for centralized storage, drum pumps, and palletized distribution to multiple docks and work crews.

Key Features & Benefits for Commercial Use

  • High output concentrate: Acidic formula with phosphoric acid and biodegradable surfactants targets waterline stains, rust, scum, algae, barnacle residue, and shell marks on fiberglass and gel coat while keeping cost per hull service predictable.
  • Restores and protects surfaces: Removes yellowing and rust staining on hulls, lower units, and trailers, helping maintain a clean, professional appearance for charter fleets and storage customers.
  • Controlled acid system: Phosphoric acid base (pH 1–3) delivers strong cleaning performance without the harsh fume profile of many hydrochloric acid drum products, supporting safer application in busy yards.
  • Efficient, low residue rinsing: Formulated to rinse clean with minimal streaking, ideal for rapid turnarounds and high volume bottom cleaning programs.
  • Bulk handling ready: Standard 55 Gallon Drum format integrates with metering pumps, proportioning stations, and pallet racks for organized inventory and chemical control.

Professional Usage and Dilution

For heavy rust, waterline stains, and severe marine growth, apply concentrate with acid resistant sprayers or brushes to cool, dry surfaces below the rub rail. Allow brief dwell time, then rinse thoroughly with fresh water. For routine maintenance or lighter staining, use through proportioning equipment at approximately 1 part cleaner to 4–5 parts water, or follow your standard operating procedure for acidic hull washes. Always test on a small area and avoid prolonged contact with metals and sensitive coatings.

Safety and Compliance

According to the Hull Cleaner Safety Data Sheet, this product is classified as causing skin irritation and serious eye damage, with corrosive hazards associated with phosphoric acid. It is supplied as a UN 1805 Phosphoric Acid Solution, Class 8, Packing Group III. Operators should wear chemical resistant gloves, eye and face protection, and suitable protective clothing when handling the concentrate. Provide ventilation, avoid breathing mist or spray, and prevent uncontrolled releases to waterways by following your facility’s wash water capture and disposal procedures. Always review the latest SDS and incorporate it into site safety training.
