what products do you use?, any special techique? and any protection product out there to stop the blue wearing and fading?

cheers.

depends how dirty they are mate, if they're quite grubby, wet wiping (off shelf interior cleaner) them will probably smear on suede. If it's that bad, a good wet vac will be required.
As for protection, you can get fabric 'protection' (not sure how they go on suede) but more for spills and stains to a degree, basically the idea is to 'repel' water from seaping in but i wouldn't really bother. It's more the rubbing that wears the material, if you're that concerned get some seat covers made, but for the price of wrx seats, put away 50c a week just in case your seats wear after time and buy new ones
