Have you been cleaning your records? I would suggest first you find an album you know well, which doesn't sound the the way it use to. Then find someone (record store maybe?) who offers ultrasonic cleaning, get the record cleaned and then listen to it to see if it sounds better.
If your album does sound better after having it ultrasonically cleaned, then delve into looking for a better cleaning solution
I'd also double check your players set-up and verify your stylus isn't worn.
If all your looking for is a cleaning solution, I'd recommend getting a Degritter.
