The RaceGlaze leather cleaner and leather feed are very good and leave a matte finish if that is what you require. The smell is not too strong either. Just used some tonight on my A4.
Otherwise there is also the Zymol leather cleaner and milk from the normal range, not the high end one. This is also pretty good. They would give you better results than the A/G range.
If you need the colour restored due to wear and tear etc, this is also available from RaceGlaze. (
