Soaking in White Vinegar Water: Soak the facial cleansing puff in diluted white vinegar water (approximately a 1:3 ratio of white vinegar to water) for 5 minutes to kill bacteria using acetic acid.
Boiling Water Sterilization: Alternatively, immerse the facial cleansing puff in boiling water for 5 minutes. High temperatures effectively kill bacteria.
After washing, rinse thoroughly and air dry.
Precautions: Avoid using cleansers containing alcohol, fragrances, or strong alkaline substances, as these may damage the material or irritate the skin.**
Material Compatibility: PVA or sponge facial cleansing puffs are highly absorbent and will harden after drying. Simply dampen with warm water before reuse to restore their softness.
Replacement Cycle: Even with regular cleaning, it is recommended to replace the puff every 1-2 months. Replace immediately if it hardens, discolors, develops an odor, or becomes damaged.
Recommendation for Sensitive Skin: Prepare two facial cleansing puffs for alternating use, ensuring they are completely dry before each use.
