You can use your detergent just do a extra rinse cycle
All brand baby detergent is good too. it's not as expensive as dreft
If sensitive skin runs in your family or the fathers use baby all. My daughter has eczema and very sensitive skin and the dermatologist said its the safest and has the less dye.
I love dreft and the spray stain remover they make works wonders!
I use all free and clear
