Thanks for your inquiry, tostados.......I use a regular vacuum attachment, probably made for cleaning furniture, about 3inch across. I hold it close to the record that I've just cleaned, but not touching it. I realize this poses some danger of scraping the lp surface, so I put a rubber 'bumper' around the mouth of the vac attachment. I buy a length of rubber hose from the auto parts store. Cut a slit in the hose from one end to another.and slip it around the mouth of the attachment. If the playing surface is actually touched by the vac attachment, the rubber will prevent damage. I think a small vacuum attachment with built in bristles would be easier, but the ones I've found have too stiff bristles. Many other people modify a crevice tool by opening up one side for the length of the tool., But you'd have to put some sort of scratch guard on it as well.
The best advice I can offer is check the forums, You tube and any other public media sources. There really are tons of methods for record cleaning. I'm probably going to upgrade to a VPI machine, but I enjoy doing the DIY method and saving money, .Allmost forgot, I use a battery powered hand vac over the table, plinth and playing surface for every play. Just a little insurance against pops and scratches
