If you don’t have dish soap, instead try using shampoo or laundry soap.

Mechanic soap usually has a strong odor. Don’t throw your other clothes into the washing machine with your jeans, or else all of them may smell like the mechanic soap.

Don’t give the coke longer than about 2 hours to soak in, or else the coke may stain your jeans.

Try using cornstarch or baking soda if you don’t have coarse salt. These may also act as abrasives that can soak up some of the grease.
