Frequently Asked Questions (FAQs)

1. What can I spray on my engine to clean it?

Thoroughly spray the entire engine compartment with degreaser. Any household degreaser will work, whether it's a kitchen cleaner or a purpose-made engine degreaser. We've used Simple Green (we like its eco-friendly formula). Don't hold back—every square inch should be covered.

2. Can I spray degreaser on my engine?

Spray the degreaser over the entire engine and let it soak for the recommended time. Apply additional coats (if needed) to really greasy areas. Then rinse with a water mist, using as little water as possible. An engine degreaser works best when the grease is warm and soft.

3. Is WD-40 good for cleaning engines?

To do this, grab that handy degreaser spray, WD-40® Specialist® Fast Acting Degreaser Spray. This fast-acting, solvent-based degreaser can effectively remove grease and grime from your engine without leaving residue.
