Magnetic disk substrate cleaning agent |
| abstract |
PROBLEM TO BE SOLVED: To provide an appropriate etching property without impairing the flatness of the surface of a magnetic disk substrate and a good dispersibility of particles detached from the substrate surface, realizing an excellent particle removability, and a production yield. Provided is a substrate cleaning agent for a magnetic disk that enables highly efficient high-level cleaning that can improve the rate and perform cleaning in a short time. A magnetic disk substrate cleaning agent comprising a chelating agent (A) having at least four phosphonic acid groups in a molecule. [Selection figure] None |
