ConclusionOptimum condition can be summarized as follows:
Among the four factors and levels tested, Coca-Cola (A) and theinteraction between time (B) and temperature (C) and Cotton (D) is themost effective factors for removing rust.
The experimental results indicated that the optimum conditions areCoca-Cola as main material, 10 minutes time to hold, 40oC temperaturewhile experiments, and cotton as a media to eliminate rust.
