I have an Accord 2007 Hybrid V6 and I want to wash my engine bay (very dirty). I've looked online and most people just spray cleaners and use a garden hose to rinse it down then apply coating afterwards. Some people go a step further and wrap sensitive areas (e.g electrical components) before washing. I was wondering if there are any places I need to protect before washing it with water since this is a Hybrid? Most people don't disconnect the battery as well. I've attached photos just in case. Thanks.
