Ultrasonic Record Cleaners from HumminGuru

Perhaps counter-intuitively, one should not just up and clean a really dirty disc. Any loose debris should be brushed off (HumminGuru makes a nice one), wiped up with a microfiber cloth, or snagged with a sticky lint roller. There is a filter (actually a screen) at the bottom of the trough designed to trap pet hair, dead insects, or whatever weird stuff detaches from the vinyl. This filter can be removed for cleaning with the multi-purpose tool. The air intake filter is under the power button end, and can be changed without a tool.

OK, we are now ready to insert the LP into the machine, making sure it is seated in the slots at both ends of the trough and the central support above the bottom filter. Select a Clean mode, press the start/pause central button, and the disc will slowly rotate counter-clockwise, in and out of the fluid. The HumminGurus are much quieter than vacuum-style cleaners, but they are not silent and sound slightly different, but our microwave seems louder. The LEDs on the Nova light up sequentially to monitor progress, but neither unit provides an audible signal upon completion. I just use a cheap kitchen timer.
