Hugs the outer threads of your bottle neck and lid rim, lifting film and residue without a single scratch.

Slides deep into the tightest lid gaps and straw holes — the exact spots where mold and slime hide.

A firm, angled bristle tip that scrubs interior corners, base seams, and stubborn coffee stains.

Pops out silicone gaskets and rubber seals so you can finally clean underneath — no prying with a fingernail.

Reviews
A small handful of feedback from our first customers. More coming as our community grows — yours could be next.
“I pulled the silicone gasket out of my Stanley lid and nearly gagged — black gunk everywhere. The twisted wire got into every gap. My Quencher finally smells like nothing again.”
“Been using the same Hydro Flask straw lid for a year and thought it was clean. Nope. The stiff corner brush pulled out stuff I don't want to describe. Worth every penny.”
“Cleans the threads on my Yeti lid perfectly and the rubber seal hook lifts the gasket right out. Sponges and bottle brushes never touched half of what this reaches.”
