Hello. We have updated the spine and pen loop material with a high quality material that is resistant to cracking. If you would like to use some Armor All on the vinyl materials it could add extra protection, but we cannot guarantee it will not stain or ruin the binder. But we believe the new material will be fine on its own.

Never use Armor All on leather, faux leather, vinyl, rubber, or nylon. Armor All contains petroleum distillates which actually dries and cracks whatever it comes into contact with, including your hands. You have to apply it over and over to prevent the drying and cracking. Most of the products that shine your tires contain petroleum distillates. The best thing for leather and faux leather is leather lotion or leather conditioner. For vinyl you can use a vinyl conditioner or leather conditioner. Clean nylon by wiping with a damp cloth. I have a nylon, faux leather (which was ran over by a car), and a leather FranklinPlanner cover. All were purchased in the 90s and are still in good shape considering what I would put them through and I only applied a small amount of leather lotion occasionally or would clean the nylon with a damp cloth as needed. Would actually continue to use one of them if I didn't need something that could also hold my phone.
