I have used a big (cobbler big!) brush and a cotton towel to scrub hard and wisk the leather to a brilliant shine if the oils are still extant in the leather and that worked well. Do not use acetone or alcohol to hasten the process, they will dry out the leather and you run the risk of it tearing, that happened to me with some vintage shell cordovans and it broke my heart. If you must cheat, you can actually use nuetral polish in small quantities on a cloth and the polish will come right off onto the towel each time you apply it and rub. This can safely be done on burgundy and black shell, I wouldn't do it to a lighter shell color for fear of slightly darkening the leather. You give us some b4 and after shots please! At some point I'll buy the saphir and crema nubiana products that the serious guys here on SF use on their shoes (RIDER, REBEL 222, Distinctive, etc). Thats how you get the awe inspiring shine! Use the Saphir Renovateur... $25 shipped from Will's store isn't going to break anyone's bank!
