Mine is part #DCC-V510, called a Val-U Series Wash. It was not expensive and has worked great for the past 4 years on my layout. Once all the wheels are clean and all the track is clean the cars seem to be good for a year, judging from when I see slight flickering of illuminated cars. The high traffic areas of the track need a quick cleaning about every 3 months. I am using the MTH nickle silver flex track.
I estimate I operate the layout on average about 5 hours/week. Not having to clean the track frequently is a major improvement from when I was using the citrus based cleaners. It did not matter on my 5'x9' seasonal layouts with Gilbert track but on this layout I have 700' of track of which 40% is hidden.
