You get a long crevice tool with the Shop Vac. Plug the opening at the end with caulk. Cut a narrow slot the length of the flat part of the tool. I used my table saw very precariously; a Dremel might be safer.

Cut 2 narrow strips of the paint pad refill and glue on either side of the slit. Work 3 or 4 drops of the RRL around on the record with a carbon fiber brush. The Audioquest clone from garage-a-records is perfect. You'll have to thoroughly wet the brush and then a few more drops gets the record wet enough. Vacuum 2 or 3 rotations and repeat. let dry 20 minutes.
