I can't handle any perfumed detergents. I actually get sick when I stay at my MIL or SILs house if I have to lay on their pillowcases. The scent of that stuff makes me gag - I think they use Tide. SIL uses Dreft on her baby clothes and it also makes me nauseous. Any time someone gives me baby clothes or gives mine back to me after I let them borrow them and they have used a perfumed detergent, I feel like I have to wash the stuff 2-3 times just to get the stink off.
We use the Meijer brand ecowise free and clear on our clothes and diapers or if I'm energetic I often make my own detergents with castille soap and borax.
