Remove the seats or leather items from the interior of the car if necessary. Then begin with a good vacuuming and cleaning, paying special attention to removing the dirt and grime in the seams. Use a leather cleaner product on a damp sponge or a soft clean cloth and rub in a circular motion to remove the initial dirt. For grimy spots, use the product with a soft bristle brush. Liquid Leather Scuff Master recommends Gliptone Liquid Leather Gentle Cleaner, so that’s what we used on this 1997 Jaguar XJ6. Remove any cleaner residue and gently wipe the area with a mild solvent like isopropyl alcohol and allow the leather to dry thoroughly.
Examine the worn or faded spots on the leather surface to decide if the quality of the leather for restoration will have sufficient integrity. Also, any imperfections you see at this stage will be amplified after dyeing. You can remove these with a light sanding using 600 grit sandpaper and follow with a final cleaning.
The driver’s seat, as you see below, has quite a few creases and is highly worn on the left side panel - but the leather is still in good shape and a prime candidate for dying and conditioning.
