Cleaning tanks before closing

[jazzbazzfazz]

Fuel tanks:

I took a 2+ year hiatus between prosealing my interior ribs and completing the tanks. I'm now at the point of attaching the rear baffle, but the interior of the tanks has various chaff, nubs and detritis inside. I'm building in a hangar, and things just get a little dirty over time. Not caked on, mind you, but just somewhat dusty/grungy.

Does anyone have a recommendation about how best to clean the tanks before sealing them up? I'm tempted to just use a H2O-based degreaser followed by a thorough rinse and complete dry...is there any problem with doing this?

I have no experience with this, but I'd probably use Dawn dishwashing detergent and water. It cuts grease and dirt well and rinses away clean. YMMV.

I agree with Mike. Dawn works great and is cheap. Your wife probably already has some.
I'm getting ready to close my bi-plane tanks within this week and that's what I'll be using.

Sounds good...Dawn it is.

Thanks!
