I cut my foot. How do you take care of it best?

Antibiotic cream. If the cut is not deep clean it with soap and water and apply neosporine cream and a bandaid. Make sure to let the area get lots of air after the first few days. If the cut is deep you will need to get it stiched.
Depends. If the cut is not deep and does not need stitches it can usually be cared for by cleansing with soap and water and applying a topical antiseptic and band aid.
