What is your experience with the Spin Clean?

Good points @moonwatcher. As I already have acquired an ultrasonic tank (Vevor 6L, 50kHz) and LP spinner (the discontinued VinylStack), I have no need for or interest in the Humminguru. I also have long owned and used a VPI HW-17 (which I like much more than the Nitty Gritty it replaced), and still use it in conjunction with the ultrasonic.

Lots of amateur reviewers have found the Humminguru ineffective at removing fingerprints and heavy soiling. If one buys only new LP’s that may not be a problem, but for buyers of used LP’s it certainly is.

I now pre-clean used LP’s in the kitchen sink (as per Neil’s suggestions), then deep clean (hand held brushes, cleaning fluids) on the VPI (why I like it's LP platter), then into the ultrasonic, then back onto the VPI for a final rinse with pure distilled water (what I fill the VPI’s reservoir with) and dry (two revolutions on each side is all it takes. Any more than that and static may be created), and finally into a new Vinyl Storage Solutions inner sleeve. Perfection!

You can get the Humminguru, the spare parts, and all Neil's recommended chemicals, for $500.

@jjbeason14: Great info and advice from Neil (@antinn). I would get a pack of the replacement parts (filters, pinch rollers) while you’re at it. Yes, the only difference is the inclusion of adapters for 7" and 10" discs.

And be sure to read Neil’s treatise of record cleaning, which contains everything you need to know. In it you will read about doing a pre-cleaning in your kitchen sink, a step I now include in my LP cleaning regimen.

In that tome you will also find advice and recommendations for cleaning and surfactant (to reduce water tension) chemicals: the former being Alconox Liquinox, the latter Talas Tergitol 15-S-9, both readily available at reasonable cost on the internet.

Anyone deciding to go for a Spin Clean type product, be sure to check out the Knosti Disco Antistat (goofy name!) mentioned by @oldaudiophile. I did, and deduced that it is a better version of the same idea as the Spin Clean, in that in place of the SCs "pads" uses very fine camel hair bristles instead.

The Knosti is available for under a hundred bucks, but for far less than that you can get the plastic LP holder that Neil recommends (I got mine on ebay for under twenty bucks), and wash LP’s in your kitchen sink, using a paint brush pad (for getting into corners) or your favorite brush (an old Discwasher?) to get the surface gunk off, then rinsing with tap water (at this stage of cleaning tap water will suffice). When putting your dirty LP’s directly into a Spin Clean or the Knosti, all the removed gunk is released into the water in their tanks, rather than going down the drain in your sink. Even if you use one of those cleaners, do a pre-wash in the sink first. That will keep the water in your Spin Clean or Knosti (or Humminguru, for that matter) tank cleaner.

@jjbeason14: The price of buying directly from Humminguru is a little over $400 (including shipping). You can include a replacement pack of water filters & rubber pinch rollers, and/or a second water "tank" in your order, saving on shipping costs in the future.

You can put together a DIY ultrasonic for far less than the price of the Humminguru, but that will not dry your LP’s as does the HG, and no water filter. And there is an ultrasonic listed on Amazon at a price of $220, a 6L US tank with an LP spinner attached. Again, no drying function or filter.

By the way: the price of the Humminguru on Amazon went up $50 in the past few days, now selling for $549.
