-Keep the puff clean at all times. When the puff is dirty, picking up product with the puff may become more difficult and it may wear out more quickly. If it becomes dirty, wash it by gently squeezing it in a warm solution of mild soap, rinse it well, drain it and leave it to dry in the shade.
-If it becomes unpleasant to use, or if it fails to create a good finish, it is advisable to replace it by buying a new puff. Store the puff on top of the refill lid.
