1A cleaning product (often powder or paste) used to remove grease and stubborn stains; often contains an abrasive.
キッチン用のクレンザーで鍋の焦げをこすり落とした。
I scrubbed the burnt spots off the pot with a kitchen cleanser.
浴槽の水垢にはクレンザーがよく効くが、塗装面には使わないでください。
Cleanser works well on bathtub limescale, but don't use it on painted surfaces.
クレンザーは研磨性があるので、傷つきやすい素材には向かない。
Because cleansers are abrasive, they are not suitable for materials that scratch easily.
