Powerful Grease Removal for Cleaner Engines & Easier Vehicle Maintenance

A clean engine bay tells a very different story from a neglected one. Hidden beneath layers of oil sludge, grease build-up, diesel soot & road grime can be leaking seals, worn hoses, coolant stains & mechanical issues that often go unnoticed until routine servicing begins.

Boston Engine Degreasers are formulated to break down heavy grease, petroleum residue, hydraulic oil, engine oil, transmission fluid deposits & stubborn workshop contaminants from engine bays, engine blocks, transmission housings, differential housings & mechanical components. They're trusted by mechanics, fleet operators, agricultural contractors & industrial maintenance teams who require reliable cleaning solutions before inspections, repairs & preventative servicing.

Experienced technicians rarely clean an engine in isolation. Many workshops begin by servicing moving components with Boston Lubricants, maintain braking systems using Boston Brake Fluid & complete vehicle presentation with Boston Automotive Car Cares once mechanical work has been completed.

Unlike household cleaning products, dedicated engine degreasers are designed to dissolve petroleum-based contamination while preparing engines for leak detection, component replacement, preventative maintenance & professional workshop servicing.

Why Choose Boston Engine Degreasers?

Finding an oil leak is difficult when every surface is already coated in grease. Cleaning first allows technicians to diagnose faults more accurately, complete repairs efficiently & monitor equipment with greater confidence.

Boston Engine Degreasers provide:

► Fast removal of grease, oil sludge & engine grime
► Helps expose coolant leaks, oil leaks & damaged seals
► Removes diesel soot & accumulated workshop contamination
► Suitable for petrol engines, diesel engines & industrial machinery
► Supports preventative servicing & workshop maintenance
► Improves visibility across engine bays & mechanical assemblies

Many maintenance professionals also keep Boston Cleaners & Degreasers available for surrounding workshop equipment & use Boston Air Duster Sprays to remove loose dust from electrical housings before servicing sensitive components.

Common Applications

Preventative Vehicle Servicing

Routine engine cleaning makes scheduled servicing more efficient while helping technicians identify developing problems earlier.

Common applications include:

► Oil leak detection
► Engine bay detailing
► Pre-service inspections
► Scheduled maintenance

Commercial Fleets & Transport

Keeping fleet vehicles clean underneath the bonnet helps minimise unexpected downtime while improving maintenance efficiency.

Frequently maintained:

► Delivery fleets
► Trade utes
► Council vehicles
► Heavy commercial fleets

Fleet maintenance strategies are explored in One Year On The Tools: What We Learned & What's Next, where preventative servicing helps reduce costly downtime.

Agricultural & Heavy Machinery

Working around mud, dust, crop residue & hydraulic oil creates demanding maintenance conditions that require heavy-duty degreasing.

Ideal for:

► Tractors
► Harvesters
► Excavators
► Loaders

After removing grease & oil contamination, many operators use Boston Rust Removers to treat exposed corrosion before ongoing maintenance.

Workshop Rebuilds & Machinery Restoration

Clean components improve access during repairs while supporting more accurate inspections.

Suitable for:

► Engine rebuilds
► Gearbox servicing
► Machinery refurbishment
► Workshop equipment maintenance

Product Selection Guide

Using complementary Boston maintenance products creates a complete workshop servicing system that supports inspection, repair, corrosion control & long-term equipment reliability.

Expert Tips

Professional workshops know that cleaning is one of the most valuable diagnostic tools available. Removing contamination before servicing often reveals problems that would otherwise remain hidden.

► Allow engines to cool before applying degreaser
► Cover exposed electrical connectors, alternators & sensitive electronics where appropriate
► Allow the product to dwell on heavy grease before rinsing
► Clean engines before replacing seals, hoses or gaskets
► Use compressed air or Boston Air Duster Sprays to help dry difficult-to-reach areas after cleaning where appropriate
► Inspect belts, radiators, coolant hoses & engine mounts once the engine bay is clean
► Dispose of contaminated runoff according to local environmental requirements
