Clean plastic bottles
I recently bought a noble water bottle. Carbonic acid and acidic liquids always attack the plastic, so after a while a plastic bottle always looks slightly rancid.
At the store, I was told that it's best to rinse them off with a small splash of hydrogen peroxide (2% or 3%). Works great, the bottle looks like new afterwards. Rinse well!
Hydrogen peroxide is available in the pharmacy, 200 ml is enough for a while. In a Internet pharmacy costs such a bottle between 3 and 4 euros. 2% have to be mixed separately, 3% are usually finished.
I wish you success!
