I have about 3-4 gallons of Hydroflouric (sp) acid left...we used to mix this with water in a weedsprayer and spray on all my dads polished Aluminum on his Peterbuilt...let it sit a bit, then rinse off.

Anyway..it's labled as "Aluminium Brightener" the jug says "mix up to 50-1"...it also says does not exceed 60% strength (I take this as it sits in the jug).

Anyway, thought on using this to clean the rust inside a fuel tank?

I'd thought about mixing it maybe 20 parts water, and 1 part of the solution (would actually be about a 40-1 mix of water to HF).

Thoughts?
