Removing Sand Residue from Casted Parts: Cleaner Selection Is Critical
Jake Fisher, Technical Sales Engineer
Surface finishers are continually challenged with selecting the right cleaners to remove sand residue on casted parts. The main reason for this is that sand --- typically a silicon-based compound--- is insoluble in water, which causes the detergency of the cleaners to be lost.
Detergency is what allows the cleaners to pull soils into the solution and remove them from the part’s surface. The sand (or silicon) itself does not affect the detergency of the cleaner; it simply isn’t acted upon by it. With sand residue, good solution movement is critical, as you must rely on mechanical forces to remove the sand.
