As per care instructions:

Sheepskin Suede

• Sheepskin suede leather is renowned for its exceptional softness, light weight, and natural insulation. Because its supple hide, sheepskin is less abrasion-resistant than cowhide or horsehide, and should be treated with a bit more care.

• To clean, use a soft, dry brush to remove surface dirt, but do not aggressively scrub. If the leather gets wet, allow it to dry naturally at room temperature, away from heat sources and in a position where it will not be stretched. Consider using a speciality suede or nubuck cleaner if deeper cleaning is needed.

What type of dry brush do I need? Would a crepe rubber brush work?
