Most bottles are not dirty — they are haunted. Coffee ghosts, tea shadows, gym-bag mystery. Two minutes a day keeps the exorcist away.
Daily: rinse hot, dry open
Hot water, a drop of dish soap, shake, rinse, and — the step everyone skips — leave it open to dry overnight. A sealed damp bottle is a science experiment by Thursday.
Weekly: brush the places you cannot see
The body brush reaches the bottom corners; the detail brush clears the lid channels where straw lids hide their secrets. Gaskets pop out — wash behind them, that is where the smell lives.
Monthly: one tablet, fifteen minutes
A deep-clean tablet in warm water lifts the stains a brush cannot argue with. No bleach smell, no scrubbing, and the coffee bottle stops seasoning your water.
Never: the three bottle sins
No freezer (expanding ice can break the vacuum), no stovetop, and no week-old smoothie time capsules. Everything else, the bottle forgives.
