Does liquid dawn dish soap lose its concentration, when the lid is off?
I was told if the lid was off, it loses concentration!
Well actually it become 'more' concentrated because the water in the mixture evaporates. The less water, the less dilution .. the 'more' concentrated it becomes. The problem with allowing it to dry out it .. it doesn't go as far it terms of how many uses the bottle will offer.
No, only when you add it to water.
