Are there any otc meds i can take that will stop the smell of bad urine? maybe cleanse?

Multiple causes...: Urine should generally not have a bad smell. There are somethings that can alter the smell of urine such as B vitamins and certain vegetables, this is usually not troublesome. If your urine is dark it may be more pungent and this could indicate dehydration, you should drink more throughout the day. If it is cloudy or painful then this could indicate infection, you need to see a doctor.
