I don't believe a microfiber towel is capable of adjusting the surface in the amount of time someone uses a spinner. Any change would be so unnoticeable....it would take over 30 minutes to polish a bowling ball from 800 to 1000, and the result would just be a sheen finish.
Also, to speak to Charlest point, there are quite a few types of Microfiber. We have a super plush microfiber towel which has absolutely no ability to remove surface, it is just too soft.
