Q: [header] How to remove smell from an old leather bag [title] Try a simple clean first. [step] If this clean doesn't shift the odor, you can try one of the other suggested methods after. [substeps] Wipe the leather bag inside and out with a clean, dry, soft cloth. <sep> (A) This will pick up dust, loose debris and even some mold or mildew. Wipe the leather bag down with a damp cloth. (B) Pour down a little dishwashing liquid directly over the odour. Washing the cleaning cloth in warm water along with it will prevent it from drying out or settling into a moldy head of the bag. (C) Using gloves to protect your hands from the chemicals, take the stained leather cloth and place it on the soiled bag. Let it sit for 10 minutes, then wipe from top to bottom. (D) [substeps] Set a low-ph or neutral or ph-free vinegar solution into the bag after cleaning. Mix it with a little water and warm water and press a few drops of the solution to the leather.
