@noromance good call. I bought one of those SpinClean units back when they released the clear version. Maybe a dozen or more years ago? It was nuts to watch it turn water + old record into chocolate milk… I still wonder if it was a pre-programmed chemical reaction from the included solution 😜 (it wasn’t - distilled water alone achieved similar result).
SpinClean works a bit differently than a strong jet of water. I got my SpinClean to deal with nasty surfaces of a big old pile of second-hand records acquired years earlier. Wasn’t a fast or particularly easy process compared to a cheap spindle x faucet (which I wasn’t using then), but I agree both ways sure can help.
Checked for curiosity - SpinCleans are a bit more expensive nowadays. Still a better price-to-performance ratio than buying an automated cleaner for many (most?) collections IMO. If automation is required, I suspect a car-to-cleaner-ready hifi shop would indeed be the better bet for many (most?) folks!
