Stanley Quencher 40 oz: what it is made of
The steel inside is the good part. The questions are the lid, the straw, and the sealing dot at the base.
The Quencher scores 74/100. Your drink sits in 18/8 stainless steel. Stanley does not name the lid and straw plastics. Stanley says the vacuum seal contains some lead, covered by a stainless layer.
It is a disclosure score out of 100, not a safety rating. We do not lab-test; we score what the maker publishes. How we score.
The score, and why
Mostly inert. Steel where the drink sits; the parts you sip through are not named.
- 60/60 What touches your drink. The inside wall is 18/8 stainless, which Stanley says is grade 304 and 90% recycled.
- 8/25 Lids, seals, handles, outside. The lid and straw are plastic, and Stanley does not name the polymer. The outside is powder coated.
- 6/15 Backed up. The steel grade and the lead seal are explained on Stanley’s own pages. Named lab reports would earn more.
