my white laptop touchpad is going yellow, please help?

so I only got my white laptop about 2 months ago and the white touch pad is going yellowy and it looks horrid cause of I guess just grease from fingers and stuff. the ideal solution is to get a touchpad cover but I literally cant find anything on the internet that does them! also someone suggested a tiny bit of bleach to me, would that work? or would it ruin it? please if you have any suggestions atall please help
