Finally got the dark tea stains out of my travel mug rim. It feels so satisfying to see the edge look clean again after weeks of scrubbing with just a sponge.
I use this every day now. The small corner brush fits perfectly into the groove of my lid where the coffee always hides. Makes cleaning up feel way less like a chore.
Good for those impossible spots on my commuter bottle. It reaches deep down and gets the bottom clean without me having to wedge my hand inside the glass.
This really saved my favorite ceramic mug. I used to hate the brown buildup near the rim but this tiny brush makes it disappear instantly. So happy with this purchase.
Simple tool but it works wonders on my gym water bottle. No more gross residue in the threads and it hangs right by my sink so I never lose it.
