Common sense should prevail here, basically, don’t be a dirty bugger Keep your piecing clean, with the solution provided by your piercer, or by using rock salt/sea salt (not table salt) mixed with boiled water. Ensure you have clean hands, or wear latex gloves when cleaning.
Be gentle and soak any crust away. DO NOT pick the crust off! Pat dry the area afterwards, as moisture can encourage bacteria bubbles.
Everyone is different, so some piercings can take a year or more to properly and completely heal, particularly cartilage. Touch your new piercing as little as possible. Try to not catch the piercing, avoid wearing clothing that will rub, try to avoid knocking it and basically follow the piercer’s instruction and your sparkles will soon look delightful.
