What did clean linen smell like before the invention of ‘Clean Linen’ scented fabric softener?

Because whatever it smelled like… Presumably like some other kind of fabric softener… Wouldn’t that logically mean that this new ‘Clean Linen’ scented fabric softener would have to smell exactly like the scent of fabric softener that people used to use when cleaning their linen before the invention of ‘Clean Linen’ scented fabric softener?

Or have I made an incorrect assumption somewhere here?*

Don’t people have any new ideas anymore? Everything is a remake these days. Apparently even fabric softener scents…

_{* I do, of course, realize that fabric softener scents don’t follow any sort of logical rules. If they did, ‘Spring Rain’, ‘Mountain Spring’, ‘Surf’ and ‘Morning Dew’ would all smell exactly the same. Like nothing. Like water.}
