◇If the sponge becomes dirty, it will be difficult to apply foundation, so always keep it clean. ◇If the sponge becomes dirty, apply about 1mL (slightly larger than a 10 yen coin) of Shiseido Sponge Cleaner N (sold separately) directly to the dirty area without wetting your hands or sponge, gently rub the sponge with the pads of your fingers to blend it well with the dirt, and rinse with water or lukewarm water. Alternatively, dissolve a mild detergent in lukewarm water and gently press the sponge to wash it. After rinsing thoroughly to remove all detergent, drain the water and dry well in the shade before using again. ◇If the feel or finish of the sponge becomes poor, purchase a new sponge.
