I washed once a day with baby wash when my DS had it. Eventually it will just go away but I found that this and a light scrub with a soft wash cloth really helped.
I've been washing w a mild soap (unscented dove) every day. I also read about wiping a mixture of baking soda and water on it to cleanse, but have yet to try that. We don't use lotion, but will use coconut oil occasionally.
Re: baby acne
I apply Neosporin to any scabby areas and Aquaphor to scaly or peely spots.
