Depends: if you put the clothes in the dryer then no. If you have a stain (or smell) on clothes that has not come out in the washer, the dryer will set the stain (or bake in the smell)

Moisten then treat with dish soap specifically (which is formulated for grease) you may have to repeat this process several times but if you didn’t put the jeans in the dryer then the stain should eventually come out
