I had been using colin for the past 6 years and it is good product I have seen. I use colin to clean my car, glass windows, refrigerator, television, furniture, mirrors, washing machine and even my mobile. The cleaning solution is advanced I think because it easily removes the grease and oily stains and gives a finished surface. Now this has become a common product in every house and I think it should be named a tool to promote swatch bharat. There are other small products who tried their best to beat colin but as you can see colin is the best cleaning product ever in the indian market.
