A light-duty all-purpose cleaner will clean a dirty dashboard. It will not touch the grease-packed valve cover of a diesel engine that has not been cleaned in three years, the undercarriage of a fleet truck that drives through axle-deep mud, or the engine bay of a piece of heavy construction equipment caked with hydraulic fluid and road film. Those jobs need chemistry that matches the contamination — and that is what Top Dog exists for.
Top Dog Heavy-Duty Degreaser — 5 Gallon from Polishing Systems Inc is a high-alkaline concentrate formulated for the highest-contamination degreasing jobs in auto, fleet, and industrial applications. The 5-gallon pail format is the practical working size for shops that run degreaser every day and need adequate supply on hand without moving up to drum quantities.
What Top Dog Is
Top Dog is a concentrated, high-alkaline liquid degreaser. High-pH chemistry breaks down petroleum grease, oils, carbon deposits, and heavy road film through saponification — chemically converting oils to water-soluble compounds that rinse clean. At full strength, it handles the most severe industrial degreasing tasks. Diluted for lighter use, it serves as a general-purpose degreaser for engine bay maintenance cleaning, wheel wells, and shop floor work.
Key Features and Why They Matter
- High-alkaline concentrate — penetrates and lifts baked-on petroleum grease, hydraulic fluid, gear oil, and carbon deposits that lighter degreasers cannot break down. Means fewer passes and less agitation on the hardest jobs.
- Dilutable formula — adjust concentration from heavy-duty engine bay cleaning down to light maintenance degreasing. One 5-gallon pail supplies multiple applications at different strength levels.
- 5-gallon pail — the right working format for shops doing daily degreasing work. Lower per-gallon cost than individual gallons; easier to handle than a 55-gallon drum. Can be used with a drum pump or poured into spray bottles for bay distribution.
- Versatile surface compatibility — effective on engine components, undercarriages, wheel wells, concrete shop floors, and equipment frames. Always test on a hidden area when using on painted or coated surfaces.
Critical Safety Notes
Top Dog is a high-alkaline chemistry. Always wear chemical-resistant gloves and eye protection during use. Do not use on soft metals (aluminum, magnesium) without diluting and testing — undiluted alkaline chemistry can etch these surfaces. Do not use on painted automotive finishes at full strength. Rinse thoroughly with clean water after dwell time. Do not allow the product to dry on any surface. Use in adequately ventilated areas.
Who Uses Top Dog
Fleet maintenance shops cleaning heavy-duty truck engine bays and undercarriages, agricultural equipment dealers prepping used equipment, body shops cleaning bare metal engine components before paint, heavy construction equipment cleaning operations, and industrial maintenance teams managing high-contamination cleaning on a regular cycle.
How to Use
- Dilute to task: For heavy engine grease and industrial soils, use 1:1 to full strength. For general degreasing, dilute 4:1 to 8:1 with water. For light maintenance cleaning, dilute 10:1 or higher.
- Pre-rinse: Rinse loose debris and surface dirt from the area to be cleaned.
- Apply: Spray or brush apply to the soiled surface. Work in manageable sections.
- Dwell: Allow 2-5 minutes for the chemistry to penetrate and break down the contamination. Do not allow to dry.
- Agitate: For heavy soil, agitate with a stiff nylon brush during dwell.
- Rinse thoroughly with high-pressure water. Repeat for severe contamination.
Why Buy Top Dog vs. a Consumer Degreaser
Consumer degreasers are diluted formulas designed for light household and automotive maintenance cleaning. They lack the alkaline concentration and surfactant load needed to break down the compacted, baked-on petroleum soils found in commercial fleet and industrial applications. Top Dog is professional concentration — designed for the contamination levels that come from actual commercial use, not occasional DIY engine cleaning.

Frequently Asked Questions
Can Top Dog be used on aluminum engine components?
High-alkaline chemistry can etch bare aluminum at full or high-concentration dilutions. For aluminum surfaces, dilute to 8:1 or higher, limit dwell time to 60 seconds or less, and rinse immediately and thoroughly. Always test on a hidden area first. For aluminum-specific cleaning, consider an acid-based aluminum cleaner designed for that chemistry.
Is Top Dog safe for pressure washing applications?
Yes — apply, dwell, and rinse with a pressure washer. At 5-gallon pail quantities, it is practical to load into a foamer or dilution injector for pressure-wash systems. Confirm dilution rate is appropriate for the level of contamination being treated.
What is the shelf life of Top Dog?
Stored in a sealed container at room temperature, Top Dog has a shelf life of 12-24 months. Keep the pail sealed when not in use to prevent concentration changes from water evaporation.
How does Top Dog compare to Super Red Stuff Degreaser?
Both are professional-grade alkaline degreasers. Top Dog is positioned for the heaviest industrial and fleet degreasing applications. Super Red Stuff is a proven truck-wash and fleet degreaser available in drum formats for the highest-volume operations.
