Special situations FAQ Conclusion Questions that parents actually ask themselves Why do my inserts become hard while my diapers remain soft? Is it related to hard water? Do my inserts absorb less when they are rough? Can I use white vinegar? How can we prevent this from happening again? 1. Why do washable inserts become rough? The inserts, the main absorbent elements, are the most sensitive to residue and limescale. Hard water: the mineral becomes fixed in the fibers, especially bamboo and modal. Laundry detergent residue: excess → stiffness + decreased absorption. Sun drying: UV rays dry out the fibers. Drying too quickly: radiator → compacted fibers. Insufficient rinsing: common with eco-friendly laundry detergents. See also: how to dry properly and optimal storage . 2. How to naturally soften your inserts Methods compatible with all MBDC inserts: Absorb6, Bambelis, Doux'plis, Duofit. White vinegar: 1 glass in fabric softener tray (1x/month max). Citric acid: 1 tbsp / 1 L of water – bath 30 minutes. Gentle tumble dryer: ideal for softening bamboo. Fiber massage: rub once dry. See also our ranking of absorbent materials . 3. Optimized anti-stiffness maintenance routine Laundry detergent without oily agents (no Marseille soap). Dosage adjusted according to water hardness. Extra rinsing recommended. Dry in the shade to avoid the effect of UV rays. Monthly cleaning in areas with high limestone content. Complete protocol in the 2026 washing method . 4. Special situations • Very hard water: rigidity returns quickly. See: water hardness . • Daycare/community: multiple washings increase rigidity. See: community management . • Materials: Bambelis hardens quickly, Doux'Plis remains soft, Absorb6 regains its shape in a gentle tumble dryer, DuoFit is more resistant to UV rays. FAQ – Rough washable inserts Do my rough inserts absorb less? Yes. Compacted fibers retain less liquid. Spot treatment restores absorbency. Can I use white vinegar? Only for use on inserts (never on PUL). Very effective against limescale. Does the tumble dryer damage the inserts? A gentle program is appropriate and restores flexibility. Which inserts offer the best resistance to rigidity? Modal (Doux'Plis) remains flexible; DuoFit is UV resistant; bamboo requires more maintenance. Conclusion Rough washable inserts are never a permanent problem. With a suitable routine, effective rinsing, and occasional treatment with vinegar or citric acid, your inserts will quickly regain softness, performance, and comfort —for optimal daily absorbency. © 2025 Ma Boule De Couches® — All rights reserved.
