3) Choosing the wrong type of sponge, or not cleaning it
It’s really important to choose the right type of sponge or loofah for our shower. As for all our life choices, we should prefer the solutions with the minimum environmental impact. Exfoliating bath gloves could be a good alternative to simple sponges, as they do not deteriorate, and get dry very quickly. Do not forget to clean them weekly, or store it in a well-ventilated area!
