A large boatyard during peak haul-out season can clean dozens of vessels per week. The hull cleaner supply volume for that operation is not measured in quarts or gallons — it is measured in drums. Attempting to run a commercial marine cleaning program from 32-oz bottles or even 5-gallon pails creates a constant supply management burden that takes time away from actual work and costs significantly more per gallon than drum purchasing.
Hull Cleaner 55 Gallon Drum from Polishing Systems Inc is the maximum-volume format of the concentrated acid-based hull cleaning chemistry for marine operations at commercial scale. The drum delivers weeks or months of continuous hull cleaning supply at the best per-gallon cost in the lineup, with construction appropriate for drum pump dispensing in a boatyard environment.
What Hull Cleaner Is
Hull Cleaner is a concentrated acid-based marine hull cleaning product that dissolves waterline staining, barnacle cement residue, rust staining, and mineral fouling from fiberglass, gelcoat, and painted hull surfaces. The 55-gallon drum format makes this chemistry available at the supply volume and per-gallon cost required for commercial boatyard, marina maintenance, and fleet cleaning programs that process multiple vessels continuously.
Key Features and Why They Matter
- 55-gallon drum format — maximum supply volume in the Hull Cleaner lineup. Provides weeks to months of continuous cleaning supply for high-volume commercial operations, eliminating frequent reordering interruptions.
- Lowest per-gallon cost — drum purchasing provides the best economics per gallon of concentrate across the entire Hull Cleaner lineup. At commercial marine cleaning volumes, this cost difference is significant over a full season.
- Industrial acid-based chemistry — the same concentrated formula as smaller sizes, delivered in drum format for pump and metering system dispensing at commercial throughput rates.
- LTL freight delivery — standard drum freight shipping with logistics coordination on every order.
What This Product Is NOT For
Not for aluminum, bronze, or stainless hardware contact. Not for in-water application — commercial marine use must be conducted with appropriate wastewater collection and disposal. Not for interior or soft surfaces. Full PPE and SDS compliance required for all operators. The drum format is for commercial operations only — for smaller working formats, see the complete Hull Cleaner size lineup.
Who Uses This
Commercial boatyards running year-round haul-out programs, large marina service departments, commercial fishing fleet maintenance operations, yacht management companies maintaining large vessel portfolios, and professional marine cleaning contractors working on government or commercial vessel fleets are the primary buyers of this drum. Any marine cleaning operation consuming more than one 5-gallon pail per week should evaluate drum purchasing for supply stability and cost advantages.
How to Use
- Install acid-compatible drum pump: Select a pump with seal materials rated for acid chemistry (EPDM or Viton seals, polypropylene or stainless body). Install in the drum bung.
- Dispense into working containers: Pump concentrate into spray bottles, dilution buckets, or pump sprayer tanks. Dilute at 1:3 to 1:10 depending on fouling severity.
- Apply in sections: Spray or brush onto hull sections, maintain wet coverage during dwell, rinse thoroughly with fresh water.
- Collect rinse water: Commercial boatyard use requires proper wastewater collection and disposal. Comply with all applicable environmental regulations.
- Secure drum: Reseal bung after each dispensing session. Store on level ground in an appropriate acid-compatible chemical storage area.
Why the Drum for Commercial Marine Operations
At commercial hull cleaning volumes, the drum is not just an economic choice — it is an operational requirement. The drum eliminates the supply interruptions, container management burden, and per-gallon cost penalty of smaller format purchasing that would otherwise compete with the actual work of running a commercial marine cleaning program. Marine cleaning products from Polishing Systems Inc are stocked in the full format range for both recreational and commercial marine operations.

Frequently Asked Questions
What drum pump is required for acid hull cleaner concentrate?
Use a drum pump with acid-compatible materials throughout — polypropylene or stainless steel body, Viton or EPDM seals. Standard carbon steel or basic nitrile-seal pumps are not appropriate for acid concentrate. Contact us for pump compatibility data specific to this product.
How many vessels does one drum clean?
At a 1:6 working dilution, one 55-gallon drum produces 330 gallons of working solution. A 25-30 foot vessel uses 1-2 gallons of working solution per full hull cleaning. One drum supports 165-330 hull cleaning sessions on vessels in that size range — a full commercial season for most boatyards.
How does this ship and what do I need for receiving?
55-gallon drums ship via LTL freight. We coordinate freight logistics on every order. Your receiving location needs a loading dock, forklift, or pallet jack for drum handling. Confirm receiving capacity before ordering.
Are there environmental regulations I need to be aware of when using this at a boatyard?
Yes — commercial acid hull cleaning generates acid-contaminated wastewater that must be collected, neutralized, and disposed of in compliance with local environmental regulations. Most boatyards operate under permits that specify wastewater handling requirements. Review your facility’s environmental compliance requirements before setting up a high-volume hull cleaning program with acid chemistry.
Can this be used in a spray-rinse system for continuous hull cleaning?
The drum concentrate can be integrated into dilution and dispensing systems for high-throughput boatyard use. Confirm material compatibility of all system components (pumps, hoses, fittings, nozzles) with acid chemistry before integration. Work with your system supplier to configure safe and correct dilution delivery.
