Apply warm water to the chest, without rubbing and gently. You can use a bath sponge but one that is new and specific for this purpose. Do not use one you already have at home, as you can transmit bacteria and infect the wound.If the tattoo begins to have scabs, do not remove them, let them fall off on their own to avoid friction with them. Dab the tattoo with the sponge or your hands, without exerting any pressure on it. Repeat this procedure every time you shower and even every time you wash the tattoo.
