My question is whether it's alright to do this or not. When I take it for a wash would I do any damage by popping the hood and spraying the dust off?
Every second wash, I open the hood and spray down the whole engine bay on the soap cycle and then close the hood, I've been doing this for years, my buddies that like to call me anal, when they open the hood and see the engine, it's usually "Holy F*##K", how do you keep your engine looking so new?
Conclusion: Case closed.
