Things You'll Need
WD-40 has many uses and can even remove crayon stains from clothing. However, once you remove the original stain, the WD-40 might leave its own stain behind. Since you can't throw a suede jacket in the washing machine after using WD-40, a thorough cleaning approach is needed. Many suede jackets come with small bottles of degreasers and cleaners for this purpose. If yours doesn't, you will need to purchase the materials to clean the WD-40 residue from your jacket.

Dry the jacket by hanging it on a clothes hanger until the WD-40 stain is no longer wet to the touch.
Rub the stain lightly with a suede eraser. Don't press into the fabric since this pushes the stain in deeper. Rub lightly at the top of the WD-40 stain until it starts to come off.
Brush the entire suede jacket with a suede brush. The brush helps to even out the texture of the suede and also removes any remaining WD-40.
Purchase a suede degreaser if the WD-40 stain remains. Apply the greaser directly to the stain, and blot it out with a dry washcloth.
Try using a fine, 250-grit piece of sandpaper to lightly buff out the stain, if the other methods don't work.
Take your coat to a dry cleaner to avoid damaging the fabric. A professional dry cleaner probably will be able to remove the stain and guarantee the work.
