As with any new piercing, you must take care to properly clean and understand the protocols immediately after. You may take a shower after-- just make sure to keep away strands of hair from the piercing site. You also will want to check there is a little space between your earlobe and the earring backing so that you can properly wash away dirt and pus. Use warm, instead of cold or hot water. Avoid any harsh soap; a saline solution is often recommended.
