Dear Brother / Sister,

Phlegm is not najis (dirty). When it smudges on the cloth, it will not prevent prayer from being accepted.

Mucus and phlegm are clean by the Islamic law (Shari'ah). That is, when they smudge on our clothes, they will not harm our prayer and wudu (ablution). Anything that excretes from human body and necessitates wudu and ghusl (major ablution) is najis (dirty): Urine, stool, mani (sperms), mazi (pre-seminal fluid), wadi (thick, murky liquid  discharged usually after urination), blood, pus, yellow liquid, mouthful puke, menstrual blood, and nifas (post-partum bleeding) and the blood of istihadha (blood due to a fracture in a capillary, due to an illness).

The things that do not invalidate wudu are not najis (dirty). As mucus and phlegm do not break wudu, they are not considered najis (dirty).
