What laundry detergent do you recommend?

Que Choisir has shown that powdered laundry detergents are the most effective and least likely to cause allergies. So use powdered detergent at least for washing your white laundry (these are the only ones that contain bleaching agents). Problem: They can leave white streaks on clothes if not rinsed thoroughly. For liquid detergents, we recommend L'Arbre Vert, Maison Verte, and Rainett: out of 25 detergents tested by 60 Millions de Consommateurs, these offer the best balance of performance, health, and environmental impact.
