All my filters are cleaned with sensor/lens cleaner using new microfiber cloths to prevent dust. I will disclose any visible scratch, in some rare instances I may oversee a scratch that has no bearing on pictures but also wasn't disclosed in the listing. I apologize for any error, Most of these filters fall into the 5-30 year old range, i do not list filters which will have scratches that affect images. 

Please check out my other listings for camera and golf gear
