Leather Bagnets are handmade with real leather and can be wiped and spot-cleaned. You can use a commercial leather cleaner or you can make your own. Mix warm water and liquid dish soap. Use ratio: 5 parts water to 1 part soap.
Alternate Option: olive oil & white vinegar: 1/2 cup of olive oil, 3/4 cup of white vinegar; mix and shake well in a spray bottle. Vinegar smell dissipates quickly.
