Stop buying leather/shoe polish. To clean, buff or moisturize leather/pleather/vinyl or any shiny outerwear use a banana peel. Simply rub the inside of a banana peel over the item to be cleaned and buff with a soft cloth.
I have done this to my husband's motorcycle gear and it takes off dust, dead bugs, and buffs out small scuffs and scratches. I have also used it on kids shoes, purses, suitcases etc. It does work and no messy polish it deal with. I have heard that it works with potato peels too but have not tried that yet.
