Being a truck driver he carries a thermos of coffee every day on the road and since he is not home every day the coffee stain gets so bad inside of it. I love that this a long enough to get down inside it and it works so great on the glass inside. The smaller brushes work great on the cap and the rim of the thermos. I especially like that it has a long narrow brush that works on our cups we carry for water or tea that come with straws. This keeps the straw from having that nasty taste even after washing it in soap and water.
