Four factors are significant

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