There don't seem to be many recent threads on this topic. Are there any recommendations for refreshing 30-year-old fabric seats - there aren't many stains or serious marks, or damage, they just need brightening up a bit. Non-smoker's car too. Preferably without wetting the seats at this time of year !

Stardrop liquid is a quick and easy way to do it - will make them a bit damp though but you dry them after you have cleaned with a dry cloth and won't need to dampen the seats too much.

If I've got any leftover when I give my flat's carpets a clean (when the weather gets a bit warmer so they can dry out a bit quicker), I might use the remainder of my HG carpet cleaner (about £7 for a 1L bottle from Tesco) on my car seats.

That make seemed to get good reviews generally, as does the Karcher 'Puzzi' carpet cleaner I'll likely hire (last time I looked it was costing about £35 - £40pw) to do the job. I'd need the extra upholstery attachment though.
