How do I get rid of red stains/marks on my LG Shine phone??

Question:Hi, I got a LG Shine phone recently and I read that it got scratched so easily so I got a red microfibre cloth <the one where you clean your glasses> and I was constantly wiping my phone.And after a day or so, the sides of the phone and the top and bottom of the phone has got red stains/marks because of the red microfibre cloth.What can I use and how can I get rid of the stains/marks? All considerations would be appreciated.Thank you very much and awaiting your answers.

I have a white phone and recently blue ink stained the side. i used rubbing alcohol and elbow grease to get it off.
