In the home fragrance industry, most wax melt warmers look perfect during sampling. However, real problems often appear only after weeks of daily use. One of the most common issues we observe involves the wax melt dish, especially inner coatings or decorative finishes.

Repeated heating cycles (typically 60–80°C), combined with scented wax melts and fragrance oils, can gradually affect coated surfaces. Over time, this may lead to peeling, discoloration, or residue buildup — even when the electric wax burner remains fully functional. For end users, this quickly becomes a perceived quality issue.

At our factory, we evaluate wax melt warmer designs based on long-term performance, not just initial appearance. By focusing on real-use testing and material compatibility, we help OEM and private label buyers reduce customer complaints and improve product durability in EU, UK, and US markets.
