Unverified去污膏研磨颗粒的莫氏硬度决定安全性：白刚玉(硬度9)去污强但易划伤，碳酸钙(硬度3)较温和，选购时优先碳酸钙基或标注'不伤釉面'的产品，尤其用于卫浴陶瓷84% similarUnverified去污膏根据研磨剂粗细分级：微粉级（碳酸钙/白泥，粒径＜5微米）适合漆面、亚克力、屏幕等易划伤表面；粗颗粒（含石英砂或硅藻土）用于瓷砖缝、水泥地、金属锅底等硬质耐磨表面，两者不可混用82% similarUnverified含研磨微粒（如碳酸钙/石英砂）的清洁膏靠物理摩擦去污，用在抛光釉面砖、玻璃、亚克力上会留划痕，这类表面应选纯化学溶解型无颗粒膏82% similarUnverified涂层不粘锅、大理石台面应避免强碱及研磨型清洁剂，大理石为碳酸钙材质，碱性和酸性均可能损伤光泽，需用专用中性石材清洁剂82% similar
