Removing canvas texture [2018]

HI all. I really need some help with this. Im taking photos of some oil paintings with a camera, cropping in photoshop etc. the problem is the texture of the canvas is visible in the image and It looks not so good, on the other hand I want to save as much detail as possible. Can anyone tell me how to get rid of the canvas lines/texture? if its even possible.

Thank you very much
