Scrim dragging

I’m new to trad cleaning but getting better by the day. Currently I use a scrim cloth for detailing/ removing lines, I find that on certain parts of the glass it seems to drag.
Any ideas what is causing the cloth to drag? It’s as if the glass needs to be polished to get a smooth surface.

Pure linen with oils washed out is highly absorbant. This means on dry glass it is high friction. Try using it very slightly damp and use a lighter touch. As you wipe the glass ‘feather off’ i.e. reduce the pressure progressively as you wipe then lift off.
