For topical piercings, clean your new piercing daily with warm water and unscented, antibacterial or antimicrobial soap. If needed, use a cotton swab to gently remove any buildup around the piercing.
Use H2Ocean or another piercing saline solution to irrigate your topical piercing at least twice a day.
For oral piercings, rinse your mouth thoroughly with antiseptic mouthwash or salt water after every time you eat, drink, or anytime you put anything in your mouth. Also rinse when you wake up and before you go to bed. Use a sterile bandage or sterile dressing when necessary/applicable and minimize your exposure to dirt, and bacteria for the first 6 weeks.
