45 sound better be4cause it's like running tape at higher speed where more data on tape per inch buit of course they have to be flipped more often.If you get them and or have a large collection nothing beats a vacuum cleaning machine like the VPI.I find that of qll the cleaners eydc the LAST power (pre) clener and eithe LAST or Disc Doctor cleaner for main claning then the LAST preservative whch hardens LP's and prevents wear.I make up my own home crew to clean Lp's even though companies like VPI male resonably priced cleaners but I amke a home bvrew by taking clewan ampty pot.First dump water into it.Then I put pinto of isopropyl into jug followe by two or three DROPS of dish liquid and same two or three drops of chemical goten at any phot shop Kodak Photflow a chemical which serves to reduce water tension so it foes not bead up allowing it to flow across and fully coat LP.A clean LP is a happy LP.Short of a vaccuuum machine a $40 Alssop Orbitrac with replacable pads does a very good job.I use for very dirty Lp's I use one to pre-clean very dirty garage sale Lp's so I don't gum up cleaning LP's that would gum up cleaning pads on the VPI tubes pads.Aftee this major cleaning that takes many steps just and occasional pass on the machine or use the Orbitrac to keep them dust free with a few zaps of Zerostat gun to static from the cleaning process causes or from other sourcdes so Lp's don't atrack.With Lp's cleanliness is next to godliness.
