Liquid abrasive cleaner compositions |
(57) The invention relates to liquid abrasive cleaning compositions containing particulate
abrasive materials stably suspended therein. Increased classification of the particulate
abrasive materials allows the use of particle size distributions with higher mean
size, resulting in very good cleaning performance. By classification to a particle
size distribution such that the classification ratio between the upper cut-off particle
size and the mean particle size is equal to or below 2.5:1, products are obtained
with very good cleaning properties and reduced surface damage.
