monotaro Cerium oxide abrasive

This product uses high-purity cerium oxide powder, which easily removes fine scratches, scale, and stubborn limescale from glass. It leaves little polishing marks, achieving high transparency. Since it's a powder, simply transfer it to a separate container and add water to adjust the concentration to your desired level. (A 50/50 ratio works best.)
For removing fine scratches and scales from glass.
*Dents and chips caused by stones or sharp objects, as well as large or deep scratches caused by falls, may not be removed. *Do not use on uneven glass, frosted glass, or objects with specially treated surfaces. *Always clean the polishing surface before use, as this may cause scratches. *Test on an equivalent material before use. *Removing dirt may make previously invisible scratches more noticeable. *Wear protective gear such as safety glasses, a mask, and rubber gloves when using. *Concentrating polishing on the scratched area may cause distortion, so polish the surrounding area while checking the repair status. *After use, store this product tightly sealed and away from direct sunlight, high temperatures, and humidity. *Keep out of reach of small children. *If you experience any irritation on your hands or skin, discontinue use immediately. If inhaled or in eyes, rinse thoroughly with plenty of water. If pain or discomfort occurs, consult a medical professional.
