Whats good at removing marks in learther seats, and what is good to bring back the shine in the leather.

im looking at upgrading to leather/valore seats out of a ghia into my car,
and they need s clean up on the leather.

hey bunter i think most interior cleaning stuff rejuvenate the leather ( the dear stuff lol) i think maquairs have a leather one ... i haven't had a look in autobarn lately but i think there are various products from different leathers to high grade leathers... just shop around i think that would be the best bet... but who knows a modder might reply and say product x or product y cause blah blah blah

just hope the leather is still softish cause once it goes hard from wheather it is hard to bring back to life

Bunter,
Go to a saddlery, there are a few out your way, shoe repairers are too dear, and ask them to show you what they've got to clean, restore and preserve leather seats. You'll probably be given at least a saddlesoap and a tin of Dubbin restorer/preserver. For anything to do with leather, find a saddle shop near you, it's their trade. This is what I do for the Merc's seats, our lounges and any thing else leather that needs repairing or preserving.
At a pinch a cloth damp with warm soapy water can be used to clean the seat, but then rub the Dubbin well in, after wiping dry, to keep the leather supple.
