If you routinely pump your own gas or get out of your car for any other reason at a gas station, it is likely that you will inadvertently step into gasoline at least once. The smell from the gasoline can linger on your shoes and the liquid can stain the shoes. Standard shoe cleaners may stain and even ruin leather shoes. However, you can make your own cleaner to safely remove gasoline odors and stains from leather shoes.
Combine the cream of tartar and lemon juice in a bowl.
Mix the ingredients until a paste forms inside the bowl.
Dip a clean, dry lint-free cloth into the paste.
Wipe the paste onto the leather shoes where the gasoline stain (or odor) is and rub the paste into the shoes.
Let the paste remain on the leather shoes for about 15 minutes.
Remove the paste from the leather shoes using a clean lint-free cloth.
Repeat Steps 3 to 6 using two different cloths.
Inspect the leather shoes and repeat the entire cleaning process if the gasoline or its scent is still noticeable.
