I've tried a few products for wet-cleaning my pre-owned vinyl and, I must admit, this stuff does a rather admirable job for the price. It's still a solution made of dilute isopropyl alcohol so there's not much to differentiate it from the pricier alternatives. It makes light work on greasy fingerprints and brings back that new-vinyl sheen, plus you get a good 250ml of the stuff, which should last some considerable time.
The only pitfall is its instructions. What you get is a sealed bottle that you have to pierce with a pin, plus a flimsy piece of cloth in the lid. You have to squirt a bit of the solution onto the cloth (or a velvet cleaning brush for a deeper clean) and wipe that around your record. This is all well and good, but the cloth doesn't really go deep enough to get the ground-in grime, and has a tendency to shed its fibres over your record. Instead, I squirted some of the solution into a clean, empty spray bottle so I could apply it directly to the vinyl and work in with a microfiber cloth. It evaporates quite quickly, so I have to be quick. I then play each clean side through a couple of times on 45rpm to let the stylus dig out the remaining gunge, brushing it clean after each play. The results are quite decent - I've tried it on a few records so far with a noticeable noise reduction; even on records that were particularly dirty and manhandled.
If you're on a budget and see vinyl as an inexpensive source of music entertainment, you can't go wrong.
