| 摘要 |
An aminocarboxylate- or polycarboxylate-containing cleaning product manufactured or sold in association with a brand may be replaced by a substitute similarly-branded cleaning product or cleaning system containing less of one or both of the aminocarboxylate or polycarboxylate, and containing (or used with a water treatment product containing) sufficient magnesium compound to provide commercially acceptable cleaning performance when the substitute cleaning product contains or is used with hard water.
