I got the Proses "ultimate track cleaner",waste of time and money, it was useless.My grandchildren bought me a Proses Multi Angle cradle that is very nice from Micro-Mark for Christmas.
Gone back to the trusty vacuum and washer system.by the looks of that track cleaner, it looks pretty complex for doing a basic task.
I use a few packs of Dust Monkeys under a string of weighted gondolas to clean the track prior to an op session.
