The wipes worked very well for cleaning my scope and eyepieces. For the optics I used gentle movements to work the lens cleaning solution on and off. The wipes did not scratch or mar the coating on the optics.. For the exteriors, the wipes (and a little elbow grease) did a great job removing the dust and grime accumulated over the years.
Very good product for lens cleaning. I would recrecommend these wipes for telescope lens cleaning.
