So I've been driving myself crazy trying to get my UHS pads clean. I've been using a mixture of CG pad cleaning solution with a little spot cleaner mixed into a spray bottle and spraying it directly onto the pads and scrubbing with a pad brush. It gets them a little clean but not fully. Recently after some polishing I filled up a bucket with a mixture of APC and CG and warm water. I let them soak for 2 days and took them out and scrubbed with a pad brush. It still came out looking and feeling dirty. Any body have any suggestions about how to clean it? Thanks ahead of time.
