Cartilage piercing care help?

Ok so i just got my upper cartilage pierced, and i am extremely confused. I got it done at claire's and their care sheet said to clean it with the antiseptic they gave me and to twist the earring a few times and slide it back and forth, so i do that.I have had no problems with my piercing besides the normal tenderness and it is kinda red and a little warmer than usual... But then im on the internet and reading off of a body piercing website that says claire's anti septic orr any type of peroxide or neosporin doesnt work and is actually bad for your ears and twisting and moving the earring just irritates the piercing and that sea salt soaks work best. It also said that the piercing being red and being warm are signs of infection. Then i move on to the next site, which says claires antiseptic works fine and so does hydrogen peroxide and the sea salts are a waste of time. It also siad that reddness and a warm feeling are normal. Pretty much every source i go to is a different variation of one of those..help?! What should i do?
