Hi, i have run a side detailing business for several years now so hopefully this helps.
Please do not use a magic sponge on leather it will age very quickly.
my go to leather products are from The Leather company. They do a cleaner and protection balm. Great combo and great company, the owner is very passionate and is willing to give advice on anything leather so check them out! They do a leather cleaning brush which is designed to clean thoroughly and carefully with hollow fibres.
