Neat and just what I'm looking for... but Rated 4 out of 5 stars
Some sort of visual indicator would be helpful for testing. This is similar to NetCaptors cleaning methods, and I do like the silent approach for long term usage, but for testing... without examining your code in great detail, it would nice to have a visual progress indicator that could show me how many passes, what it's cleaning, etc.
Thanks for the work so far! :)
