Tangential to topic, but I also keep foil handy as an instant clean work surface (and of course other uses;) great tip.

I’ve always wondered if aluminum foil is a “bug free” surface when used straight from the roll. It seems that it is.

I would think it's not sterile but probably sanitary enough. I spray with starsan to quell any worries. I've not had an infection that could ever be traced back to using foil

I don't spray foil that is used as a lid, it doesn't come in contact with the wort. I spray foil that I use on starters or that I use to lay things on that might touch beer

I use unsanitized foil straight rrrom the roll all the time, including covering starters.  Not a problem so far in hundreds of uses.

They make it by extruding it between rollers.  I figure no bugs could survive the heat generated.  And beer spoiling organisms are not likely to hang out in foil factories anyway.  I too use it right off the roll with no worries.

Mr. Google says AL foil is sterile off of the roll.

Think of all the food that is wrapped with AL foil with no issues.

Sterile on the roll in the box. How long does it stay sterile once I pull off a sheet and lay it on a bench in my shop?

If it's sterile, I'd think it's as already as sterile as it will be after you sanitize it.  You're just up against the dust falling out of the air, which will always be there.  If I'm going to leave something a while, I'll just cover with another piece of foil.

I don't autoclave anything in my brewery so its really just something fun to volley back and forth lol

I take that back... my starter wort is autoclaved
