I just cleaned 200 albums. 100 I used the VPI brushes that come with the HW1. The other 100 I used the Mofi brushes. My results were interesting. I found the Mofi brushes much easier to use and control to protect the record labels. However of the 100 cleaned with the Mofi brushes, I had to re-clean 18 due to noise level - 3 did not improve. With the VPI brushes I had to re-clean 6 and of those 6 only 2 made significant improvement with a second cleaning. I realize it is not scientific, but the sample size was big enough to point to the VPI brushes doing a more thorough cleaning job than the Mofi brushes - which is a disappointment to me because I fund the Mofi's easier to use (although threads coming loose on the Mofi brushes seems to be a problem). Has anyone had a similar experience? If not how do you improve on the results with the Mofi brushes? (all 200 albums were thrift store buys and all were cleaned with the AIVS 3 step system).
