Can I use Release the Grease on a hot engine?
No – let everything cool down first. Spraying products on hot manifolds is a recipe for a headache and baked-on active ingredients won't work as well as intended.
Do I need to cover anything before using it?
Ideally, 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. But most modern engine compartments are pretty secure and protected, just keep high pressure water away from the bay, don't let chemicals dwell for extended periods and rinse everything thoroughly.
Can I dilute it?
Yes, 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?
Detailing brushes (like our Hog Brushes) are ideal for agitating stubborn grease.
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 dressing like Dark Matter for that factory-fresh look. Or use Future Armour for longer-lasting, high temp protection - even if the finish isn't as shiny.
