cleaning a center section?

I just took my center section and a body housing down from the attic of my garage. wire brushed it down, wiped it clean and painted it. Before I install my center section I was wondering If you guys reccomend anything to clean or spray in the carrier before I put it all together. Brake cleaner?Carb Cleaner? Hopefully this isnt a stupid question I just have never done anything like this before. Any other reccomendations for my install while were on this topic?

Thanks all
Joe
