Cut through the heaviest grease, oil, and grime with this industrial-strength degreaser from Star brite. Engineered for high-volume marine and commercial cleaning applications, this ready-to-use formula delivers professional-grade results without dilution — just apply, agitate, and rinse.
The 5-gallon carboy format is built for operations that demand serious cleaning capacity: boatyards, marinas, engine rooms, and commercial maintenance facilities where a spray bottle simply won't cut it. The distinctive purple formula is highly concentrated and fast-acting, breaking down petroleum-based soils, bilge grease, engine oil, and hydraulic fluid on contact.

- Ready-to-use — no dilution required for full-strength cleaning
- Fast-acting on engine surfaces, bilge areas, decks, and mechanical components
- 5-gallon carboy format ideal for high-volume or commercial use

Parts Desk Insights
Best Use Case: This is the go-to choice for boatyards, marinas, and serious DIY operators doing full engine bay cleanouts, bilge degreasing, or seasonal haul-out prep. The carboy size makes it practical for refilling spray bottles or pump sprayers across multiple jobs. Apply directly or via pump sprayer to engine blocks, stringers, bilge surfaces, and greasy deck hardware — let it dwell for 2–5 minutes on heavy buildup, then rinse thoroughly. For routine maintenance cleaning, dilute up to 4:1 with water to extend the supply further.
