Microfibre scrims ( the big ones) last for years and don't wear thin and go into holes!
Wash them without fabric conditioner. 'Window Cleaning Warehouse' sell their own and are good quality and price.
Cheaper microfibre cloths are good for sill wiping (very absorbent and long lasting).
Better quality microfibre cloths (Unger sell these, they are small size) are good for polishing lead windows leaving less smears.
