What is a material burned for its pleasant smell?
scented oils but that's an opinion
It depends on what you mean by smell. If there is a pleasant aroma, then that might signify you having bathed correctly, congrats! If the smell is a bitter one, then it could be a bacterial infection on the feet or fungi. I would consult a doctor to see if that's a problem. If it doesn't smell bad, then lay back, relax and smell the pleasant smell of soap.
