Can I use Release the Grease on a hot engine?
No – let everything cool down first. Spraying solvents on hot metal isn’t clever, and it won’t clean any better.
Do I need to cover anything before using it?
Yes. Protect sensitive parts like fuse boxes, ECUs, and air inlets with cling film or plastic bags. It keeps the water and cleaner where they should be – on the grime, not in your electrics.
Can I dilute it?
You can. A 50/50 mix with water works fine for lighter cleaning or if you’re being frugal. But for maximum grunt, use it neat.
Is it safe on paint and plastics?
Yes – just rinse thoroughly after use. It’s designed for grimy engine bays and underbodies, so plastics and painted metal panels are fair game.
What tools should I use with it?
A detailing brush (like our Hog Brushes) is ideal for agitating stubborn grease. Follow up with a pressure washer or hose to rinse.
Will it damage rubber hoses or seals?
Not when used correctly and rinsed off properly. Don’t soak rubber endlessly – clean, rinse, and dry.
How should I dry the engine bay afterwards?
Old towels or rags work fine. Once dry, you can dress plastics with a trim or engine bay dressing for that factory-fresh look.
