First record cleaner

I've used a Spin Clean over 10 years, because I always find excuses to not take the plunge. Someday, in this lifetime I'll get a proper machine.

Spin Clean makes for a clean appearing LP more than anything. The Project unit gets good reviews, and it's relatively inexpensive.

If you want to do it just once-consider a US machine. The Audiodesk and DeGritter users can chime in. The times I've used one, it does what it's supposed to do.

Machines won't miraculously make a groove damaged LP quiet.

There's always that ridiculous glue method

Look into the original record cleaning machine ever made for the BBC, Keith Monks. 

IMO, assuming cost is a consideration, get a Nitty Gritty. It’s compact, reliable and you don’t have to leave the records drying in a dish rack.  Their Pure 2 fluid is also fine for cleaning most records. If that’s too expensive, you can get a Record Doctor for about $200 and I’m sure it will be fine as well. Audio Intelligent #6 is a good 1-step cleaner to start with. The high-end ultrasonic machines are the best, but you’re talking 3-5k. Buy one if you have the $$.

I would think that most would recommend an ultrasonic record cleaner.  The shiny, best ones are a few thousand dollars, but you can get a VEVOR ultrasonic cleaner for records for only $200, and it seems to work quite well…

I would also suggest an ultrasonic cleaner.  It's the most effective way to clean records.
