Right GuardSport Unscented Aerosol Antiperspirant Spray 6 oz (Pack of 3)

Is it truly unscented!?

I can’t find it on the cans, but when do these expire?

Anyone notice any residue on clothing after application?

Can I check this under a plane if I am travelling or will they remove it? I would not bring it in a carry-on, on board...
