$Na_2CO_3$. Sodium orthosilicate (Na-OSi), Tetronix T-701 (T-701), Na-dioctyl sulfosuccinate (303C), Newpol PE-68 (PE-68), MJU-100A, and tetrasodium pyrophosphate were blended to prepare high performance alkaline cleaning agents (ACASs). The results of cleaning test with steel specimen showed that ACAS-6 ($Na_2CO_3$ 50g/Na-OSi 35g/T-701 20g/303C 18g/PE-68 17g/MJU-100A 10g/TSPP 20g/ water 180g mixture) had a good cleaning power. The cleaning power for press-rust preventing oil was 98% and 99% degreasing at 4wt%, $70^{circ}C$ and $90^{circ}C$, respectively ; for quenching oil, the cleaning power of ACAS-6 was 91% degreasing at 4wt% and $70^{circ}C$. The foam heights measured immediately after foaming by Ross & Miles method and Ross & Clark method at 6wt%, $60^{circ}C$ were 18mm and 65mm, respectively. It was concluded that ACAS-6 had a good low foaming cleaning agent.
