anti-static record cleaning arm


I have seen these "dust bugs" on ebay and other iterations of the same. LP gear has an "anti-static record cleaning arm."

Have not seen any discussion of these devices in this forum and am wondering if they have any benefit. The prices are certainly cheap enough for a try.

thanks

Dmgrant1, carbon fibre brushes are like using a broom with out a dust pan, you can sweep it around but it is difficult to really pick it up. Most folks slowly wipe it to the side but IMHO I feel it just smears it and the dirt is not so noticeable. The wiping action also creates static that wasn't there before unless it was created the last time you used the brush. IMHO the Milty Pixall is the only dry cleaner that works.
Headshappin, point well taken and makes good sense. Have you tried the Nagaoka rolling cleaner? Don't have a Milty, but they seem to be similar. Where can I get a Milty?
I used a dust bug way back when until I heard artifacts through my headphones late one night. My stylus was in a silent space between tracks, but I heard "stuff". Lifting the dust bug made the noises go away. Apparently, the bristles running in the grooves set up vibrations either in the record, or down into the plinth through the bug's arm and mount. Upon checking platter speed with a strobe, I found it also slowed rotation about as much as the stylus did. That was it...the bug got squashed.
