Never use feminine washes, they actually make things worse! You can use an unscented soap on the outside like @maeve_ mentioned but definitely use only water if you don’t have that. The vagina cleans itself, it doesn’t need help. Discharge is the result of your vagina cleaning.
What does it smell like? What is the texture and colour of your discharge like?
Also for the future, don’t see it as “clean”, it implies that people which might carry a STI are dirty, and that’s not the case xx
