I used Discofilm (Last?) long time ago and it's still on the market. You evenly distribute the liquid on your disc and it takes at least 6-8 hours to solidify. It's intended that dust and dirt will be imprisoned in that plastic foil and you just rip it off and all is fine...
Maybe I'm not very talented in applying this method, but after tearing off the foil there were still some left-overs on the surface in the grooves, not visible but audible like an explosion when the stylus hit them high level. The stylus could have been damaged by plastic residues still there. There was no chance to remove it again without a cleaning machine.
I never tried it again because of this experience, I think it's pretty expensive and only suited for people investing years to clean their collection.
Cleaning a record on my machine takes max. 5 minutes and I have the best result I can ever get. Maybe you want to try, but be careful when applying this stuff.
