Pour facial cleanser, makeup remover or powder puff cleaner on the powder puff, gently press it with the thumb of both hands to completely melt out the makeup inside the powder puff, then put the powder puff in a fresh-keeping bag, and gently press the powder puff with the thumb to help squeeze out the foundation hidden deep inside. Don't rub it, otherwise the powder puff will be easily damaged. When the cleaning agent dissolves the foundation contaminated in the puff, rinse the puff with clear water, then add the cleaning agent to continue to press out bubbles, and wash it several times. Press the moisture in the puff dry with a dry towel or paper towel, and don't wring it out or expose it to the sun, otherwise the puff will easily break or crack. Just put it in a cool and ventilated place and dry it naturally. After using the air cushion puff, gently wipe the surface with a paper towel, which will keep the puff clean and prolong its service life.
