Yes they are still safe....
What do you mean by "The aluminum keeps coming off"?
Club aluminum si heavy, solid aluminum and wonderful to cook with! If you scrub with a stainless steel pad, you may remove bits of the surface, because the steel is harder than the aluminum. Use a soap filled brillo or SOS pan....it's gentler.

I read your posting in iVillage Garden forum about Club Aluminum today. I have a set of club aluminum that I got for my wedding 32 years ago. Since my husband has been cooking chili and other tomato-y stuff in it forever it has gotten very pit-y and dark inside. The food is always delicious though. I read the previous posting that says that the aluminum can't rub off, but does the tomato acid make the cookware unusable in any way?

I would think that a stainless steel pad would, in fact, scratch into the aluminum causing it to flake off/wear down. You'd be better not to use something too abrasive, just use a scrubby or a green scrub pad, not stainless.
