Finally Destroys The Hidden "Biofilm Hotspots" That Make Your Bottles Smell (Even After Washing)
You've been fighting the wrong battle.
The main chamber of your bottle? That's easy to clean. But the real problem—the source of that lingering odor and potential health risk—is the bacterial biofilm breeding in places your round brush can't access:
- The tight threads inside screw-top lids
- The groove underneath rubber seals
- The interior of reusable straws
- The tiny vent holes in sippy cups
This 5-in-1 system was specifically engineered to eliminate these "Micro-Crevice Hotspots" with three game-changing tools:
- ✅ Crevice Brush – Stiff, narrow bristles that penetrate deep into lid threads and grooves, physically breaking up hidden gunk.
- ✅ U-Shaped Brush – Perfectly contoured to scrub curved cup rims and lid edges where residue clings.
- ✅ Seal Hook – Gently lifts rubber gaskets to expose (and eliminate) the nasty buildup underneath—without causing damage.
The result? Your bottles are actually clean for the first time—not just surface-level clean.
"I lifted the seal on my Yeti lid with the hook tool and nearly gagged. Black gunk EVERYWHERE. Been using this bottle for 2 years and had no idea. This brush is a lifesaver."
