Gotta break up the aluminum, other commenters have named good products I would just add that a LONG soak (overnight) will help. Long soak with whatever product you decide to use, then maybe scrub at it with an old toothbrush before washing
If that + the tips others have left doesn't cut it, I have heard of people turning shirts inside out and spraying the stain with CLR ("calcium, lime, rust", a brand of sink/bathroom cleaner for hard water stains and mineral build up). Wash immediately after, if you let the CLR sit for too long it might destroy it the cloth. I've never done that and I'm not sure what effect (if any) this has on the texture of the clothes, so maybe try it with a shirt that's otherwise doomed haha
