Look, jj, even clean records can have static. Two separate issues.
Cleaning is the biggest benefit.
After that, deal with static. The best way known to mankind is, sadly (one does not like to support a company selling fake junk), the Furutech Destat III. All the same, do not save up for this until you can get your disks clean. There are cheaper ways of reducing static (Zerostat, brushes etc) but they don't work as well.
