8 Way of Cleaning Cast Metal :
Use manual way with steel brush and beater Use mechanical auxiliaries Blasting Teknologi dan Rekayasa

9 Use Manual Way with steel Brush and Beater
Usage with banding surface of cast metal until sand patching on surface to lose. This way modestly done but result less cleanly and less effective big scale Teknologi dan Rekayasa

10 Use Mechanical Auxiliaries
This devices has limitation especially at the mechanism which is not enables for always can reach complicated parts from certain work substance contour. alat bantu mekanik Teknologi dan Rekayasa

11 Blasting semprotan pasir
1. Sand blasting is surface cleaning method by spraying sand with presure air between 6 – 7 kg/Cm2 on surface of object semprotan pasir Teknologi dan Rekayasa

12 Water injection method
2. Wet blasting Blasting sand mixed with water and element additive as inhibitor. Applied at work area that is not enabled happened firework sprinkling, for example process area/ chemical area. Water injection method Teknologi dan Rekayasa
