I know Naim recommend Astonish products for cleaning Olive cases.

I was wondering if anyone knows how to rejuvenate the dials on a NAC52.

You could call TomTom audio and see if they have replacements?

Jack, I’m not sure what you mean when you say “dials”. Are you referring to the volume and balance knobs? If so, what is the problem with the ones you have?

Yes, the knobs.

Mine are quite discoloured.

Perhaps replacement is overkill, is there a way to clean them?

If it’s just grease and grime on them then cleaning with the same window and tile cleaner as the case, or else if it’s really heavy then a fairly gentle degreasing cleaner should be OK. Use a soft cloth. The knobs are just plastic with rubber outer rims so don’t use anything that’s a solvent. Always test any cleaning product on a small area first just to be sure.
