冰箱要是長時間不清洗或清洗方法不正確也會有一股難聞的味道，這因為冰箱內有細菌的緣故，因為這些細菌在其生長代謝的過程中會產生許多代謝氣體，如甲烷，硫化氫，甲硫醇，甲基胺等發臭氣體，當菌群長到一定大的時候，散發的氣體也就更濃烈，這么多種臭氣體混合在一起就會讓您家的冰箱產生更難聞的異味。

因此，應該定期對冰箱進行清洗，由于目前家用冰箱使用頻率過高，所以每周至少一次對冰箱進行清洗、除菌、消毒。 其次是方法要正確，除了對冰箱內部常規部位進行清洗、消毒外，更應該注重用高效的冰箱專用消毒劑來對冰箱內部的滴水槽、隔板槽等死角進行噴射消毒。

冰箱內壁、死角噴霧完成后，應該將冰箱門關閉5—10分鐘，讓消毒劑充分殺菌，最后再用抹布抹干凈。 一周至少要擦拭一遍冰箱的表面。冰箱內部可以用硼酸或消毒紙巾擦拭，擱架要拿出來用水清洗；冰箱內壁用甘油擦拭，可形成一層薄薄的保護膜，即使沾上牛奶或是食物殘渣，也可以很容易地被擦拭掉。
