After you take off the bandage you'll have to wash the area - for this, use an antibacterial soap or lotion. Don't scrub the area, if you're going to use a soap, pick a delicate one. Don't use an abrasive towel, use something made out of cotton which is gentle with your skin. It would be a good idea if you'd use an antibacterial lotion (like Bacitracin) and an antibacterial powder (one could be Baneocin). For the antibacterial lotion,go at your local pharmacy and ask there what's the best. Make sure you are not allergic before. You can also use some lotions based on aloe vera...but the antibacetrial ones are the most important.
Use A and D ointment.
