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!

Thanks guys!

Fear not, the HG produces cavitation - Interesting All-in-One Ultrasonic Cleaner - HumminGuru | Page 38 | Steve Hoffman Music Forums - see Post #930.  

The HG only has 350-ml of fluid, so it does not need a lot of power and the lower kHz, the lower the power required for cavitation.  With the HG, the two 40kHz transducers (~30W ea) are located one each side, very close to the record; located exactly where the big hole is in the aluminum foil.

Just got a HumminGuru. Will try it out this weekend.

Been using a Spin Clean. Hoping the Guru will be faster and easier for one record at a time as needed. 

Depending on how many records you plan to clean, not sure about second tank for rinsing. I change my cleaning solution after about 100 records. Thats when my pmm reaches 50. I use a ppm meter to check how dirty my water is getting. I use 4 gal. distilled water, 4 oz 100% isopropyl alchol, 4 ml kodak photo flow 200. 5 min 100 degree F seems to do the trick. Then I air dry in a dust free area.
