I used a new Static-Master brush for cleaning slides prior to scanning. I tried several different techniques for cleaning my slides, including using a plain soft brush (no polonium). Honestly, I could not tell a difference in the effectiveness of the various cleaning strategies I used. Definitely not worth the extra cost for StaticMaster.Like any brush, this one cleans off loose dust and lint, but does not remove years-old specks that are stuck to the film. The specks are a far greater problem on many of your old slides.Definitely not worth the extra cost for StaticMaster.
