Date：2026-08-25Genuine leather sofa got moldy? It is one of the most common after-sales problems for sofa factories and furniture exporters. Leather is rich in protein and oils – natural mold food – and sofa production adds glue and foam that absorb moisture. This article provides a detailed sofa factory prevention plan and leather agent selection guide.
1. Why Do Leather Sofas Mold Easily?
- Leather nutrients: protein ~30%, oils 2%-3% – mold’s favorite food;
- Processing residue: EVA/PU glue and foam filling absorb moisture;
- Humidity: warehouse above 65% or container condensation wets leather (regain 14%-16%); above 18% moisture, spots appear within 7 days.

| Foam/filling | Control moisture, ventilated storage | Moisture ≤10%, humidity ≤60% |
| Finished sofas | Spray/wipe before packing | Focus on seams |
| Packaging | Sachets/desiccants | 2-4 sachets + desiccants per set |

3. How to Choose a Leather Anti-Mold Agent
- Penetration: genuine leather needs penetrating agents (0.5-1.5mm deep) – surface spray lasts only 3-6 months;
- Safety: non-toxic, odorless, meets eco-leather restricted substance lists;
- Color fastness: no color/hand feel impact – test samples first (24h observation);
- Durability: 6+ months for 30-60 day voyages.

4. How to Treat an Already Moldy Sofa
- Isolate: separate moldy sofas to prevent spore spread;
- Remove: use professional leather mold remover (never alcohol or wet scrubbing – alcohol dissolves the coating);
- Dry: air dry 12-24 hours in a ventilated shady area – no direct sun (UV accelerates aging and cracking);
- Protect: spray leather anti-mold agent after drying.
