I have a Nitty Gritty 1.5 FI record cleaning machine. I clean at very least one record every day. I'm going through the vac-sweep replacement cleaning "lips" at least one a month. They are almost impossible to find in Canada and shipping costs as much as a package of four ($18.50 a package).
I decided to try making my own. I had no success with two sided tape and velvet cut to fit. I wasn't sticky enough. I've tried some peel and stick fabrics from a fabric shop with no success. Then yesterday in Walmart (yes Walmart), I spotted some peel and stick felt packages in the crafting section. Each package contains multi-color felt in about 10" x 8" squares with a peel and stick backing. For less than $4.00 is worth a try.
Today I cut the felt to the approximate size needed for the lips and after cleaning the machine peel the backing and stick it on. I found it was just a little bit thinner than the real NG vac-sweeps so I put another layer on top. Now it's a tiny bit thick but very cushiony. I then used a razor blade to cut the felt away from the center where the vacuuming action takes place and then used a safety pin to poke the holes for the fluid injection.
I then needed a good grungy record that I won't cry over if it's wrecked. I have three copies of the Doors Waiting For The Sun and one that has clearly been through a few acid parties. I did my usual cleaning routine. Two rounds each side with the cleaning solution vacuuming in between and two rinses. It came out spectacularly clean and the glue backing held perfectly.
Eureka!!$4.00 and a little work for years and years worth of vac-sweeps. Will work with any Nitty Gritty machine.
