摘要： A method of cleaning interior surfaces of fluid delivery systems. The method comprises (a) passing through the system an abrasive cleaner composition comprising at least one liquid carrier containing solubilizable abrasive particles, at least some of which are in non-solubilized form, effective to abrade the material to be removed from the interior surfaces, and (b) rinsing the system with at least one fluid effective to (i) displace the carrier and (ii) remove the abrasive particles, at least partially by such chemical means as dissolution or decomposition or neutralization. Optionally, the method can include a first step of contacting the inside surfaces of the fluid delivery system with a pretreatment fluid capable of softening or loosening the material that is to be cleaned from the internal surfaces of the delivery system for a time sufficient to soften or loosen unwanted material. Also, an abrasive cleaning kit capable of cleaning unwanted deposited materials from interior surfaces of fluid delivery systems. The kit is comprised of: (A) an abrasive cleaner composition comprising a liquid carrier containing solubilizable but having non-solubilized abrasive particles effective to abrade the unwanted material; and (B) at least one rinsing fluid effective to (i) displace said carrier and (ii) remove said abrasive particles at least partially by such chemical means as dissolution, decomposition, or neutralization, comprising water and at least one material chosen from the group consisting of organic solvents, acids, amines, and mixtures thereof effective for such chemical removal. Optionally, included is (C) a pretreatment fluid comprising a liquid capable of softening the unwanted material that is to be cleaned from the interior surfaces of the fluid delivery system. Also compositions of (A) and (C) with and without surfactants and/or acids are provided. Additionally, cleaner compositions made from abrasive cleaner composition (A) and pretreatment fluid composition (C) of the above abrasive cleaning kit are provided.
摘要翻译：一种清洁流体输送系统的内表面的方法。该方法包括（a）通过系统使研磨剂清洁剂组合物包含至少一种液体载体，所述至少一种液体载体含有可溶性磨料颗粒，其至少其中一些是不溶解的形式，有效地研磨待从内表面去除的材料，和（b）用至少一种有效地（i）置换载体的流体冲洗该系统，和（ii）至少部分地通过诸如溶解或分解或中和的化学方法去除磨料颗粒。任选地，该方法可以包括使流体输送系统的内表面与预处理流体接触的第一步骤，该预处理流体能够使来自输送系统的内表面的待清洁材料软化或松动一段足以软化或松开不需要的材料。另外，一种能够从流体输送系统的内表面清除不需要的沉积材料的磨料清洁套件。该试剂盒包括：（A）研磨剂清洁剂组合物，其包含含有可溶化但具有有效磨碎不需要的材料的不溶解磨料颗粒的液体载体; 和（B）至少一种有效地（i）置换所述载体的冲洗流体和（ii）至少部分地通过诸如溶解，分解或中和的化学方法去除所述磨料颗粒，所述化学方法包括水和至少一种选自由有机溶剂，酸，胺及其混合物组成的组可用于这种化学去除。任选地，包括（C）预处理流体，其包括能够从流体输送系统的内表面软化待清洁的不需要的材料的液体。还提供了具有和不具有表面活性剂和/或酸的（A）和（C）的组合物。另外，提供了由磨料清洁剂组合物（A）制成的清洁剂组合物和上述研磨性清洁试剂盒的预处理流体组合物（C）。
