Although a Stanley Cup seems like it would have a pretty straightforward owner's manual, fans of the cult classic are finally taking a look at tips to use the product - and realize they have been drinking from it all wrong.

A TikToker recently shared online that when he looked at the care instructions, he realized he's never preheated or cooled his water bottle.

Oliver posted a video to the platform with his blue Stanley Cup and informed his followers that they had to preheat or precool the water bottle before filling it up with their favorite beverage.

He explained that to get the best experience out of the popular water bottle, the cup should be filled first with hot or cold water, left to sit out for a few minutes, and then emptied before the beverage is poured in.

'If you own one of these - nine times out of ten, you're using it wrong,' Oliver said, with his bright blue Stanley Cup in hand.
