Skin Irritation Question

[Crisco Salad]

So we switched laundry detergent in the last week or so. Well, J has developed a rash on his whole back and coming down is arms. My sitter and H think that it is related to the new soap because he sleeps on his back or his sides. 

So, I plan on switching back to the old detergent we were using. 

My question is, would you just re-wash once or multiple times? If multiple, how many?

Do a warm water strip there there are no bubbles. Then wash once?

I think SAK just went through this.

Water only or water with washing soda/Calgon/borax/softener of your choice until you see no bubbles at all, then one more round.

I use hot water, but I've heard to use warm or cold also. I have whole systems set up, they work for me.

[SAK]

Have they only been washed in the new detergent once? If so then yeah, I'd just wash them j warm water then again with the new detergent.

If it's been a lot of washes I'd do a couple warm strips to be sure it's out

[Crisco Salad]

They have only been washed once, maybe twice.

I will try doing a warm water wash then use the other detergent.

Thanks!
