Metalube Products Engine Cleaners & Degreasers: Industrial-Strength Cleaning You Can Trust

When grease, oil, and road grime build up on an engine, a truly effective degreaser makes all the difference — not just for appearances, but for long-term engine health and easier diagnostics. Metalube Products has built a focused reputation in the engine cleaners & degreasers category by offering heavy-duty, concentrated formulas designed to tackle the toughest contamination across automotive, marine, RV, and industrial settings.

The MC509/4U Formula: Concentrated Versatility

At the heart of Metalube Products' degreaser lineup is the MC509/4U Cleaner & Degreaser — a highly concentrated, multi-purpose formula engineered to cut through engine grease, oil residue, exhaust deposits, and grime. Because it is sold in concentrated form, a single container goes a long way: users can dilute the solution to match the intensity of the job, making it both economical and adaptable for light-duty rinse-downs or aggressive engine bay scrubbing alike.

The 4U formula is designed for use both manually and in pressure spray parts washers, giving professional mechanics and dedicated DIYers the flexibility to work the way they prefer. Its broad compatibility makes it suitable not only for engine bays, but also for parts cleaning, floor degreasing, tool washing, and RV washdown — a genuine multi-tasker for any garage or shop environment.

Safe, Responsible Chemistry

One of the most important considerations when selecting an engine degreaser is its impact on surrounding components and the environment. Metalube Products formulates the 4U Cleaner & Degreaser to be non-toxic and aquatic safe, a meaningful distinction for mechanics working near drains or in marine and waterfront environments. This responsible chemistry means users can clean engines and equipment confidently without compromising sensitive ecosystems or violating environmental best practices.

A Heritage of Quality Since 1975

The 4U product line has roots going back to 1975, reflecting decades of refinement and real-world use across automotive, marine, and commercial cleaning applications. That longevity is a testament to a formula that genuinely works — one that has earned repeat customers in professional shops and among serious vehicle owners who demand consistent results.
