On occasion I have had to remove oil stains from finger prints from the lenses. I find most any lens cleaning fluid on a microfiber cloth works. If the spot is particularly oily, I put a drop of fluid directly on the lens then use the microfiber cloth. One other thing I use that works is I buy 100% cotton diaper flannel from a fabric shop. I wash it and use a cup of white vinegar in the rinse water to keep it soft. I find it works very well and is as good as a micro fiber cloth to clean a lens. I learned it holds more cleaning fluid and does a great job of removing oil without damage to the lens. I'm sure others have their own method. This works for me.
