Cleaning aluminum parts?

[95GT_VERT]

What have people used to clean greasy, slightly oxidized aluminum parts so they look new again?

Least aggressive to most aggressive options ?

I want the parts to turn out to be like new factory look

Sadly a hot tank is likely the only way to accomplish this.
But you could try oven cleaner first, terrible stuff though, be careful.

Sandblasting works really well also

Boil water and vinegar ( 2 tablespoon of vinegar for every quart of water) in a pot and drop the part in a let it boil for 15-20 min. Repeat if necessary until you are satisfied.
