Now have had access to large ultrasonic baths and have used them on records laid flat. The labels peel off and the records come out cleaner, all the mould and dirt are gone. This is not a cheap ultrasonic bath, and I would not have had access to it normally. The records I cleaned came from boot sales and were mouldy. Don't have an amazing needle nor and amazing deck so no idea if it makes that much difference.
The specific record ones I have seen only do a certain area of the record and then you turn the record to a new area, then that gets cleaned. Not sure the ultrasonic baths are anything special such as multiple harmonic transducers.
If I needed to clean records now, I'd use car shampoo as there is little abrasive material in there and just to break the surface tension of the water, and a carbon fiber brush to clean the worn record material from the groves.

My records are mainly from boot sales and auctions so their condition is variable to say the least.
I'm considering something like this http://audiorevita.pl/ or the ali equivalent.

Does anyone know if ultrasonic record cleaners are any good? Or the best good value vacuum or DIY options? Thanks.
