What is your experience with the Spin Clean?

I have a Spin Clean and like it.  I use it for swap meet/yard sale records and think it does a pretty good job of getting the gunk out.  IMO, it makes no sense to use on new records, though.  In that case I wouldn't expect a Spin Clean to make any sonic difference which might explain some previous responses.

pdspiegal,

                       You wouldn't believe the gunk on the bottom of my Ultrasonic tank after cleaning 3 brand new albums, Amy Winehouse, Beth Hart, Chris Cornell, they are all double albums but just after those there was a ton of gunk!! It was shocking!!!  These record making plants are not clean!  I wonder if they use some kind of releasing agents or something?

I’ve used the SC for several years.  Is the best cleaner-no.  For the money it does a fair job.  All you have to do is look down in the bottom of the well after you’ve cleaned 20 albums.

I returned the Spin Clean.

Thinking about picking up the Humminguru US.

Anyone have any experience with it?

Also, what's the humminguru equivalent?
