◇If the sponge gets dirty, the surface of the foundation will harden and it will be difficult to apply to the skin, so please keep it clean at all times. ◇If the sponge gets dirty, please use the separately sold "Shiseido Sponge Cleaner N" or dilute a mild detergent in lukewarm water and gently press the sponge to wash it. After rinsing thoroughly to remove all traces of detergent, drain the water and dry well in the shade before using.
