How do you clean your engine bay?

Simple green and purple power work great, but if the engine bay is hot I’ve had issues with the purple power staining the aluminum (only had this issue with hot engine bays).

 

Those are some nice looking engines!

 

Anything containing gallium should clear out most of the engine compartment.

Behold: the Taco trunk mod.

Srsly: I use compressed air and brushes to get the bulk of the trash out. Then low pressure water and rags. Dry with clean rags. Wipe all the galvo bits with machining surface wax.

It will look (and smell) new for decades.
