Concerned about lead in your Stanley Quencher? Here’s what to know.

If the bottom button falls off, stop using it

The craze is as big as the cup.

The Stanley Quencher has become a must-have for millions as it got a wave of endorsements from TikTok creators. It was even spoofed on “Saturday Night Live.”

But the laughing ended for some people when reports of the tumblers containing lead made the rounds on social media.

So Consumer Reports looked to its partner, Tamara Rubin from Lead Safe Mama, a longtime lead poisoning prevention activist, to help guide consumers through the hype.

“Using XRF technology, we discovered that the exposed sealing dot on the bottom of the Stanley Tumblers was positive for a very high level of lead,” Rubin said.

On the bottom of the Stanley Tumblers there is a little button, and underneath that is a primarily leaded material, and Stanley melts that bit of lead into the hole on the bottom of the tumbler to create the vacuum insulation, she explained.

“Countless consumers have contacted Lead Safe Mama, and let them know that their little button of stainless steel with the logo has fallen off and that they were not aware that there was basically a hunk of bioavailable lead,” Rubin said.

Lead exposure can cause developmental problems, affect brain development, and lead to lower IQ.

Stanley’s website discloses that its sealing material does include some lead.

And Stanley isn’t alone. Many similarly designed flasks and tumblers are manufactured the same way using lead solder.

On its website, Stanley tells its customers, “Rest assured that no lead is present on the surface of any Stanley product that comes into contact with the consumer nor the contents of the product.”

If you own a Stanley Quencher and the button on the bottom falls off, stop using it immediately and contact the company for a replacement. The company does offer a lifetime warranty.

If you’re worried that your child might have been exposed to the lead, talk to your doctor about a blood lead test.
